Abstract:
The significant part of the hydrography is bathymetry, which is the empirical part of it. Bathymetry is the study of underwater depth of waterways and reservoirs, and graphic presentation of measured data in form of bathymetric maps, cross-sections and three-dimensional bottom models. The bathymetric measurements are based on using Global Positioning System and devices for hydrographic measurements – an echo sounder and a side sonar scanner. In this research authors focused on introducing the case of obtaining and processing the bathymetrical data, building numerical bottom models of two post-mining reclaimed water reservoirs: Dwudniaki Lake in Wierzchosławice and flooded quarry in Zabierzów. The report includes also analysing data from still operating mining water reservoirs located in Poland to depict how bathymetry can be used in mining industry. The significant issue is an integration of bathymetrical data and geodetic data from tachymetry, terrestrial laser scanning measurements.

Abstract:
Precise and accurate bathymetric measurements are conventionally acquired by means of ship-based acoustic equipment. Nevertheless, recent multispectral satellite imagery has been utilised as a substitute source to map the seabed topography which indicates new revolution in hydrographic surveying. This study assesses the satellite bathymetric depth’s accuracy based on the vertical uncertainty as stated in the Standards for Hydrographic Surveys issued by the International Hydrographic Organization. Two empirical algorithms, namely, Dierssen’s and Stumpf’s approaches have been adopted to model the seafloor topography over the coastal and shallow water at Tanjung Kupang, Malaysia. The outcomes demonstrate a decent correlation between the derived water depths and the sounding values acquired from a ship-based acoustic survey. For instance, a total of 1,215 out of the 1,367 generated water depths by Stumpf’s model have hit the minimum standard of survey in S-44. Similarly, out of the 1,367 samples from Diessen’s model, 1,211 samples have met the minimum requirement listed in the survey standard. The results demonstrate both imageries derived bathymetry models convey promising results which can be ultilised for bathymetric mapping application. Therefore, this imagery derived bathymetry can be considered as an alternative bathymetric surveying technique to supply cost-effective solution and survey data to support the Blue Economy and Sustainable Development Goals 14.

Abstract:
UTILIZATION OF LIDAR (LIGHT DETECTION AND RANGING) TO MEASURE SHALLOW WATER DEPTH. Understanding on seabed characteristics such as the topography, composition and habitat conditions was very important to provide information not only for shipping activities, conservation, management and planning activities, but also for research activities with accurate bathymetry data. Accurate bathymetric data can be obtained from hydrographic surveys and remote sensing technology analysis. The hydrographic survey is used to obtain bathymetry data by applying singlebeam echosounder (SBES) and multibeam echosounder (MBES). At a depth of <15m (shallow water) was difficult to carry out an acoustic survey. At present there is one remote sensing technology that can be used to support hydrographic surveys namely Bathymetric LIDAR (Light Detection and Ranging). LIDAR was able to detect objects on land and waters due to being flown by a vehicle. Wide LIDAR sweep makes data acquisition faster and more effective than acoustic noise. Therefore, LIDAR was an alternative to obtain depth data, especially in coastal areas with a depth of less than 50 m.

Abstract:
Periodic bathymetric surveys are carried out to define quantity of sedimented material in reservoirs, as well as to determine the areas most endangered by the silting process. Such surveys in the Republic of Macedonia were started as an obligatory and regular practice in the seventies of the last century, immediately after the formation of the larger artificial lakes. These were carried out for almost all reservoirs in the country and it can be said that there is already a sufficient amount of data on some of them that can serve as a basis for high quality analyses of the silting trend of the reservoirs and of the extent to which erosion is affecting the basin area. This paper provides a review of the results from the latest field surveys and analyses of changes in the configuration of the Shpilje reservoir bottom, carried out in the period 2014 to 2016.

Abstract:
One of the fundamental tasks in the maintenance of port operations is periodic dredging. These dredging operations facilitate the elimination of sediments that the coastal dynamics introduce. Dredging operations are increasingly restrictive and costly due to environmental requirements. Understanding the condition of the seabed before and after dredging is essential. In addition, determining how the seabed has behaved in recent years is important to consider when planning future dredging operations. In order to analyze the behavior of sediment transport and the changes to the seabed due to sedimentation, studies of littoral dynamics are conducted to model the deposition of sediments. Another methodology that could be used to analyze the real behavior of sediments would be to study and compare port bathymetries collected periodically. The problem with this methodology is that it requires numerous bathymetric surveys to produce a sufficiently significant analysis. This study provides an effective solution for obtaining a dense time series of bathymetry mapping using satellite data, and enables the past behavior of the seabed to be examined. The methodology proposed in this work uses Sentinel-2A (10 m resolution) satellite images to obtain historical bathymetric series by the development of a random forest algorithm. From these historical bathymetric series, it is possible to determine how the seabed has behaved and how the entry of sediments into the study area occurs. This methodology is applied in the Port of Luarca (Principality of Asturias), obtaining satellite images and extracting successive bathymetry mapping utilizing the random forest algorithm. This work reveals how once the dock was dredged, the sediments were redeposited and the seabed recovered its level prior to dredging in less than 2 months.

Abstract:
Abstract. High-quality bathymetric maps of inland water bodies are a common requirement for hydraulic engineering and hydrological science applications. Remote sensing methods, such as space-borne and airborne multispectral imaging or lidar, have been developed to estimate water depth, but are ineffective for most inland water bodies, because of the attenuation of electromagnetic radiation in water, especially under turbid conditions. Surveys conducted with boats equipped with sonars can retrieve accurate water depths, but are expensive, time-consuming, and unsuitable for unnavigable water bodies. We develop and assess a novel approach to retrieve accurate and high-resolution bathymetry maps. We measured accurate water depths using a tethered floating sonar controlled by an unmanned aerial vehicle (UAV) in a lake and in two different rivers located in Denmark. The developed technique combines the advantages of remote sensing with the potential of bathymetric sonars. UAV surveys can be conducted also in unnavigable, inaccessible, or remote water bodies. The tethered sonar can measure bathymetry with an accuracy of ∼2.1 % of the actual depth for observations up to 35 m, without being significantly affected by water turbidity, bed form, or bed material.

Abstract:
The determination of accurate bathymetric information is a key element for near offshore activities; hydrological studies, such as coastal engineering applications, sedimentary processes, hydrographic surveying, archaeological mapping and biological research. Through structure from motion (SfM) and multi-view-stereo (MVS) techniques, aerial imagery can provide a low-cost alternative compared to bathymetric LiDAR (Light Detection and Ranging) surveys, as it offers additional important visual information and higher spatial resolution. Nevertheless, water refraction poses significant challenges on depth determination. Till now, this problem has been addressed through customized image-based refraction correction algorithms or by modifying the collinearity equation. In this article, in order to overcome the water refraction errors in a massive and accurate way, we employ machine learning tools, which are able to learn the systematic underestimation of the estimated depths. In particular, an SVR (support vector regression) model was developed, based on known depth observations from bathymetric LiDAR surveys, which is able to accurately recover bathymetry from point clouds derived from SfM-MVS procedures. Experimental results and validation were based on datasets derived from different test-sites, and demonstrated the high potential of our approach. Moreover, we exploited the fusion of LiDAR and image-based point clouds towards addressing challenges of both modalities in problematic areas.

Abstract:
Accurate bathymetric modeling is required for safe maritime navigation in shallow waters as well as for other marine operations. Traditionally, bathymetric modeling is commonly carried out using linear models, such as the Stumpf method. Linear methods are developed to derive bathymetry using the strong linear correlation between the grey values of satellite imagery visible bands and the water depth where the energy of these visible bands, received at the satellite sensor, is inversely proportional to the depth of water. However, without satisfying homogeneity of the seafloor topography, this linear method fails. The current state-of-the-art is represented by artificial neural network (ANN) models, which were developed using a non-linear, static modeling function. However, more accurate modeling can be achieved using a highly non-linear, dynamic modeling function. This paper investigates a highly non-linear wavelet network model for accurate satellite-based bathymetric modeling with dynamic non-linear wavelet activation function that has been proven to be a valuable modeling method for many applications. Freely available Level-1C satellite imagery from the Sentinel-2A satellite was employed to develop and justify the proposed wavelet network model. The top-of-atmosphere spectral reflectance values for the multispectral bands were employed to establish the wavelet network model. It is shown that the root-mean-squared (RMS) error of the developed wavelet network model was about 1.82 m, and the correlation between the wavelet network model depth estimate and “truth” nautical chart depths was about 95%, on average. To further justify the proposed model, a comparison was made among the developed, highly non-linear wavelet network method, the Stumpf log-ratio method, and the ANN method. It is concluded that the developed, highly non-linear wavelet network model is superior to the Stumpf log-ratio method by about 37% and outperforms the ANN model by about 21%, on average, on the basis of the RMS errors. Also, the accuracy of the bathymetry-derived wavelet network model was evaluated on the basis of the International Hydrographic Organization (IHO)’s standards for all survey orders. It is shown that the accuracy of the bathymetry derived from the wavelet network model does not meet the IHO’s standards for all survey orders; however, the wavelet network model can still be employed as an accurate and powerful tool for survey planning when conducting hydrographic surveys for new, shallow water areas.

Abstract:
The Canadian Hydrographic Service (CHS) supports safe navigation within Canadian waters through approximately 1000 navigational charts as well as hundreds of publications. One of the greatest challenges faced by the CHS is removing gaps in bathymetric survey data, particularly in the Canadian Arctic where only 6% of navigational water is surveyed to modern standards. Therefore, the CHS has initiated a research project to explore remote sensing methods to improve Canadian navigational charts. The major components of this project explore satellite derived bathymetry (SDB), coastline change detection and coastline extraction. This paper focuses on the potential of two stereo satellite techniques for deriving SDB: (i) automatic digital elevation model (DEM) extraction using a semi-global matching method, and (ii) 3D manual delineation of depth contours using visual stereoscopic interpretation. Analysis focused on quantitative assessment which compared estimated depths from both automatic and 3D manual photogrammetric approaches against available in situ survey depths. The results indicate that the 3D manual approach provides an accuracy of < 2 m up to a depth of 15 m. Comparable results were obtained from the automatic approach to a depth of 12 m. For almost all investigated depth ranges for both techniques, uncertainties were found to be within the required vertical accuracies for the International Hydrographic Organization category zone of confidence (CATZOC) level C classification for hydrographic surveys. This indicates that both techniques can be used to derive navigational quality bathymetric information within the investigated study site. While encouraging, neither technique was found to offer a single solution for the complete estimation of depth within the study area. As a result of these findings, the CHS envisions a hybrid approach where stereo- and reflectance-based bathymetry estimation techniques are implemented to provide the greatest understanding of depth possible from satellite imagery. Overall, stereo photogrammetry techniques will likely allow for new potential for supporting the improvement of CHS charts in areas where modern surveys have not yet been obtained.

Abstract:
Morphology and movements of sand dunes are studied using repeated high-resolution bathymetric data in areas where banner banks approach the shore. Two sites in the Bristol Channel were selected for their contrasting environments. The Helwick Sands is characterised by deeper water-depths, stronger wave climates and weaker tidal currents than the Nash Sands. At the Helwick, migrations of the dunes were measured ranging between 21 and 109 hlv"1. Dunes crossing its crest and connecting despite opposite direction of migration on either flank were observed. This geometry is interpreted to be the result of the strong wave climate coupled with a nearly rectilinear tidal flow, which are leading to dune crests extension. A morphometric study of the sand dunes has revealed the tendency for the dunes to flatten in shallow water, which can also be attributed to the effect of the waves. At the Nash, strong currents and breaking waves have created a strong crestal escarpment. Dune migration rates along the flanks were measured to range from 34 to 180 m.y"1 {Text not available}, based on a comparison of surveys 263 days apart. However, in the Nash Passage (between East Nash and the coast) short term (19 days) sand dunes migration measurements revealed very fast moving (up to 715 m.y_1) small short-living sand dunes. Celerity and morphology of the dunes were used to compute sand transport specific fluxes. Such fluxes are broadly compatible with fluxes computed from tidal current data using bedload transport formulae. For both banks, the geometry of the flux vector field suggests a clockwise sand transport pattern around the banks. Although different intensities of the fluxes were expected at the two sites, the fluxes of corresponding morphological areas are similar. Differences in the tidal current asymmetry and reduced effective threshold of sand transport due to the wave energy are invoked to explain theses similarities. Pattern of erosion and deposition were evaluated from the divergence of sand fluxes. This partem has revealed the occurrence of transients in the sand transport, which are the result of complex interactions between the flow, the headland and the bed morphology.

Abstract:
Le phénomène global d’érosion côtière, notamment sur les rivages d’accumulation, tend à accroître les risques côtiers (érosion et submersion) dans les secteurs à enjeux. Dans ce contexte, les stratégies visant à la gestion des stocks sableux côtiers au sein même des cellules hydro-sédimentaires apparaissent comme une réponse potentielle à la gestion locale de l’érosion des accumulations littorales, et au-delà à la gestion de ces risques. Ces perspectives se heurtent encore à une insuffisance de connaissance des dynamiques géomorphologiques des avant-plages (partie immergée de la cellule). Pour autant, la connaissance des échanges au sein de la cellule et avec le large sont au coeur de la compréhension du fonctionnement des systèmes littoraux sableux. Les objectifs de cette thèse sont de renforcer les connaissances géomorphologiques des stocks sableux et de leur mobilité au sein des cellules littorales et, par l’amélioration de cette connaissance, de contribuer à l’élaboration de stratégies de gestion des risques côtiers.La comparaison de levés bathymétriques multi-temporels sur le temps long (séculaire) et court (annuel) à une échelle régionale et locale met en évidence les évolutions des avant-plages sur les côtes bretonnes du début du XXème siècle à nos jours. Ainsi, un des résultats majeurs est une inversion des tendances d’évolutions au milieu du XXème siècle. Une situation d’accrétion ou de stabilité relative laisse place à une érosion généralisée des avant-plages sur les côtes bretonnes. L’interprétation et la discussion de ces résultats permettent d’avancer des facteurs explicatifs de ces évolutions tels que les forçages météo-marins et anthropiques et les contraintes structurales
The global phenomenon of coastal erosion, occurring especially on sandy coasts, tends to increase coastal risks in areas with key issues and concerns. In this context, stocks management strategies within sandy hydro-sedimentary coastal cells have appeared to be potential solutions to the local management of coastal erosion and their associated risks. However, despite their importance to determine management strategies, the dynamics of nearshore (submerged part of the cell) geomorphology remain poorly studied and partially understood. This PhD thesis aims to provide a better understanding of nearshore geomorphology in some specific sites and to contribute to the development of coastal risk management strategies.The study of multi-temporal bathymetric surveys at century-scale and annual-scale highlights significant evolution of the Brittany nearshore morphology from the beginning of the 20th century until today.In particular, a striking result is the reversal of the morphological evolution tendency in the mid-20th century. During the first half-century, the situation is steady, though nearshore morphology has a slight tendency toward accumulation. During the second half-century, we measured a net erosion tendency for all the survey sites. Interpretation and discussion of these results allow to determine the forcing of the nearshore morphodynamics, among which are climatic (coupled ocean-atmosphere) events, anthropogenic impacts and structural constraints

O presente trabalho teve como objetivo realizar um estudo sobre o processo de assoreamento e sobre a qualidade das águas do Açude Velho em Campina Grande/PB. Para o diagnóstico da qualidade da água, foram determinados indicadores físico-químicos e microbiológicos em 10 pontos amostrais, espacialmente distribuídos pelo reservatório, durante o período compreendido entre março a setembro de 2016. O levantamento batimétrico foi realizado com intuito de estimar os volumes de água e sedimento no interior do reservatório, além de permitir a identificação das áreas mais afetadas pelo processo de assoreamento. Os resultados obtidos apresentaram um volume útil da água de 475.677,49 m³. Foi constatado que aproximadamente 23% do volume total do açude estão ocupados por sedimentos e, quando comparados com os dados apresentados por Castro (1994) para o ano de 1990, o Açude Velho teve sua capacidade de armazenamento reduzida em 7,7%. De acordo com os indicadores analisados, os pontos marginais do açude apresentaram uma qualidade inferior em relação aos pontos centrais. Segundo comparativos com a Resolução 357/2005 do CONAMA, a água do Açude Velho no período não chuvoso apresentou DBO compatível com água de classe 3 (10 mg/L). No entanto, no período de chuva, a DBO promoveu uma queda na qualidade da água apresentando valores superiores ao permitido na referida classe. De maneira geral, o Açude Velho apresenta características de um corpo aquático eutrofizado e com qualidade comprometida para a maioria dos usos preponderantes.
The present work had as objective to carry out a study on the sedimentation process and on the water quality of the Açude Velho in Campina Grande / PB. For the diagnosis of water quality, physico-chemical and microbiological indicators were determined in 10 sample points, spatially distributed by the reservoir, during the period from March to September 2016. The bathymetric survey was carried out with the purpose of estimating the volumes of water and sediment inside the reservoir, besides allowing the identification of the areas most affected by the silting process. The results obtained presented a useful water volume of 475,677.49 m³. It was verified that approximately 23% of the total volume of the dam is occupied by sediments and, when compared with the data presented by Castro (1994) for the year 1990, Açude Velho had its storage capacity reduced by 7.7%. According to the analyzed indicators, the marginal points of the dam were inferior in quality to the central points. According to comparisons with the Resolution 357/2005 of CONAMA, the water of the Old Açude in the non-rainy period presented BOD compatible with water of class 3 (10 mg / L). However, in the rainy period, the BOD promoted a decrease in water quality presenting higher values than allowed in the mentioned class. In general, the Açude Velho features characteristics of a compromised quality eutrophic aquatic body for most of the prevailing uses.

Abstract:
The first part of this thesis deals with studying the effect of the specified bathymetric resolution and ideal bathymetric form parameters on the output from the wave and hydrodynamic modules of Delft-3D. This thesis then describes the use of an optimization to effectively reduce the required bathymetric sampling for input to a numerical forecast model, by using the model’s sensitivity to this input. A genetic algorithm is developed to gradually evolve the survey path for a ship, AUV, or other measurement platform to an optimum, with the resulting effect of the corresponding measured bathymetry on the model, used as a metric. Starting from an initial simulated set of possible random or heuristic sampling paths over the given bathymetry using certain constraints like limited length of track, the algorithm can be used to arrive at the path that would provide the best possible input to the model under those constraints. This suitability is tested by a comparison of the model results obtained by using these new simulated observations, with the results obtained using the best available bathymetry. Two test study areas were considered, and the algorithm was found to consistently converge to a sampling pattern that best captured the bathymetric variability critical to the model prediction.

In traditional bathymetric survey, it is hard to grasp tidal error and dynamic draft. Recently, Ellipsoidally Referenced Bathymetric Survey (or ellipsoid based bathymetry), which uses ship-mounted GNSS ellipsoidal height to calculate depth, can reduce some error sources from dynamic draft and tide. In this study, ship-mounted GNSS data and bathymetric survey data which were obtained from Strong Engineering Consuling Co., Ltd and Real World Engineering Consultants Inc., the data was obtained from multibeam system checking in April 2015.(hereinafter referred to as ST SOP and CH SOP). In order to obtain high accurancy GNSS height, Post-Processed Kinematic (PPK) computation method is used by the computer packages GrafNav, Trimble Business (TBC) and GAMIT TRACK in this study. The research shows that GravNav PPK, TBC PPK computation results are more unstable when baseline is over 10 kilometers. However, whether the baseline is long or short, GAMIT TRACK computation results difference could maintain centimeter level. Based on the GNSS computation results comparative analysis, GAMIT TRACK computation results are used for calculating water depth of ellipsoidally referenced bathymetric survey in Caris software. Also, ellipsoidally referenced bathymetric survey results are compared with traditional bathymetric survey results. In the cross check analysis, ST SOP traditional bathymetric survey difference mean is 2.6cm, difference standard deviation is 8.8cm; ST SOP ellipsoidally referenced bathymetric survey difference mean is 0.1cm, difference standard deviation is 8.9cm; CH SOP traditional bathymetric survey difference mean is 4.4cm, difference standard deviation is 10.8cm; CH SOP ellipsoidally referenced bathymetric survey difference mean is 3.8cm, difference standard deviation is 10.6cm. All of the results reach International Hydrographic Organization (IHO) special order bathymetric survey and study shows that ellipsoidally referenced bathymetric survey is better than traditional bathymetric survey in cross check analysis. In this study, Surveying and mapping Center (NLSC) provide Separation model called TWHYGEO2014, which is used to transform ellipsoidal height to chart datum height. Then transformed ellipsoidally referenced bathymetric survey depth compared with traditional bathymetric survey depth. The result shows ST SOP difference mean is ~0 and standard deviation is ~3cm; CH SOP difference mean is ~15cm and standard deviation is ~4cm. Due to lack of more detailed tidal zone information in Penghu, it’s hard to judge whether ST SOP test area is the same tidal zone with Longmen tide gauge or not. But it’s obvious that CH SOP test area’s tidal zone is different from Budai tide gauge. It could be the reason why ellipsoidally referenced bathymetric survey depths are different from traditional bathymetric survey depths. Ellipsoidally referenced bathymetric survey can avoid the influence from different tidal zones. Also, ellipsoidally referenced bathymetric survey is better than traditional bathymetric survey in cross check. Ellipsoidally referenced bathymetric survey compared to traditional bathymetric survey have more advantages, it’s expected to replace the traditional bathymetric survey with ellipsoidally referenced bathymetric survey in the future.

Abstract:
O conhecimento do fundo marinho é um fator crucial para a segurança da navegação, assim como para as diversas atividades marítimas. O progresso da hidrografia tem mostrado novos horizontes trazendo diversos sistemas complexos que prometem resolver muitos dos desafios nesta área. Respetivamente à aquisição de dados batimétricos através de sondadores de feixe-simples, este trabalho surge da necessidade de colmatar os erros dependentes do fator humano, reduzir o tempo de processamento e melhorar a qualidade do mesmo. Para tal, são necessárias ferramentas computacionais que auxiliem a fase de processamento de dados e a elaboração de produtos finais. Deste modo, foi criada uma ferramenta, com auxílio a vários algoritmos e métodos desenvolvidos. Um dos utilizados é o Self Organizing Map (SOM) ou mapas auto-organizados. O estudo apresenta, sinteticamente, conceitos básicos de Levantamentos Hidrográficos para uma melhor compreensão dos dados analisados. De seguida, apresenta-se o modo de funcionamento do algoritmo SOM, abordando aspetos necessários para a realização de agrupamento de dados (clustering) como parte da solução da ferramenta desenvolvida. A partir deste, apresenta-se a metodologia desenvolvida para a realização da seleção de dados (sondas) necessária à criação de produtos para representação do fundo marinho. A ferramenta desenvolvida, Processamento de Dados Garmin com Self-Organizing Map (PDGSOM), é confrontada com outros sistemas de processamento de dados batimétricos, nomeadamente o software CARIS. Deste modo, comparando modelos batimétricos realizou-se uma análise de parâmetros de funcionamento e eficácia da ferramenta desenvolvida. Em síntese, a presente dissertação tem como objetivo a construção de uma ferramenta com uma interface de fácil utilização, fornecendo uma informação segura na utilização dos dados e produtos obtidos, tendo como motivo de estudo a “segurança na navegação”.
The need of knowledge of the seabed in its whole, has been brought many challenges to maritime navigation. The safety of navigation is a crucial factor, and even with all the progress and the new horizons that hydrography science has shown with its numerous complex systems, there are still many obstacles to overcome. Regarding the acquisition of bathymetric data with single beam echo sounder, this work arises from the need to bridge the errors reflected on the human factor, improve the processing of data acquisition and time reduction. For all the reasons stated above, computational tools are of a main importance on the data processing phase and the elaboration of final products. For this study, I developed a tool, using Decision Support System, based on the algorithm of self-organizing map Kohonen. Better known for its clustering, visualization and classification capabilities with comprehensive solutions for selection of bathymetric data. The study begins by presenting, the basic concepts for a better understanding of the studied area, with respect to the Hydrographic Surveys. Next, the operation of the Self Organizing Map algorithm is presented, addressing aspects necessary to perform data grouping (clustering) as part of the solution of the developed tool. From this, I present the methodology used to develop the realization of data selection necessary to create products for representing the seabed. The developed tool, Garmin Data Processing with Self-Organizing Map (PDGSOM - Portuguese version) is compared with other bathymetric data processing systems, CARIS software. This allowed the comparison of digital elevation models, analysis of operation parameters and effectiveness of the developed tool. Succinctly, this dissertation has as main goal the construction of a tool with an easy-use interface, providing safe information in the use of the data and obtained products, based on the principles of "safety of navigation ".

Impact conditions for the factors affecting multi-beam sonar sounding are different in the vicinity of nearshore area (shallower than 10 meters) and the deep water area (deeper than 100 meters). For instance, if the dynamic motion sensor of the system was not located on ship''s gravity center, the measurements could not be true heave values induced by the heave motion only. Thus, if the heave motion was compensated without going through properly correction procedure, the quality of the multi-beam sonar survey data will deteriorate as the water gets shallower. In addition, the ability of patch test is feckless if it was conducted in the area where the water depth is too small; as a result.. to satisfy precision requirements for the multi-beam sonar survey, roll offset angle is the only parameter needed to attend to its accuracy. As to pitch and yaw offset angles, their influence to data quality becomes insignificant. Nearshore of estuary area, the river and sea water can be stratified by tidal motions, such that a distinct top layer is present in the acoustic velocity profile. Therefore, several acoustic velocity profiles shall be obtained in different time and area to make the correction to the refraction of ray path. The last factor is from tide correction effect, the error correction can not be identified easily as survey conducting in the area where water depths are small. This is because that when the track lines are short such that surveying interval to the next track-line is separated at several minutes away, we will lose the crud to identify the error caused by ill correction that induces track-line effect.

Abstract:
The paper presents analysis of determination of vertical movement of the surveying boat called “heave” with the use of Robotized Total Station (RTS) technique. The classical geodetic Total Station was used for sub-centimeter calculation of water level changes during hydroacoustic measurements on the fragment of Vistula river behind the dam and hydropower in Włocławek in Poland. The power station work causes up to 1.7 m movement of vertical reference water surface in aspect of local bathymetric survey. The experimental, hydrographic surveys on the river were conducted where the water level was changing significantly over time depending on the operational schedule of the power plant. Verified hydrographic data had to be brought to the common water level. To determine the final water level, data on the height of the Robotized Total Station prism positioned on the boat during sounding was considered. The RTS technique with 0.02–0.05 m vertical accuracy proved to be very useful and essential in engineering inland bathymetric measurements.

Full text
Abstract:
The main field of application of a multi-beam echosounder is hydrographic surveying, in other words acquisition of bottom topography information. This kind of bathymetric data is needed by a large number of users for harbour and coastal zone management, resource exploration, hydrographic charting for safety of navigation and many other tasks. Tools for highly efficient investigation of the seafloor, including rapid sediment classification, as well as reliable object detection are of high interest to offshore construction projects. Throughout the last couple of years, ATLAS Hydrographic has been concentrating on the development of the next generation of hydrographic survey echosounders. One of the results is the ATLAS FANSWEEP 30 family of multi-beam echosounders (MBES). This family of sonars offers an innovative new approach of multi-beam echosounder technology for hydrographic surveys. The ATLAS FANSWEEP 30 COASTAL, the first member of the ATLAS FANSWEEP 30 MBES family, is breaking new ground. Innovations, such as Simultaneous Multi-Ping, wide bandwidth transducer, multiple time and multi-view scanning of the seafloor for object search, address a single purpose: to improve survey efficiency while multiplying data reliability and resolution. With the FS30C the new Simultaneous Multi-Ping (SMP) is introduced. SMP utilises the complete frequency range between 100 kHz and 200 kHz to transmit and receive eight frequency separate pings at every ping interval. Four of these eight pings are forward, the other four backward looking mapping the seafloor from two independent directions. Thus, every bit of the mapped seafloor is looked at from two different directions. The 8x Simultaneous Multi-Ping enables the hydrographer to run the survey operation at high speeds. Still, the 8x SMP can ensure more than 300% bottom ensonification. That means every patch of seafloor is measured at least 3-times at one pass. The gained data redundancy is used to enhance not only data accuracy and reliability, but in particular the capability to recognise objects on the sea floor. Beginning at signal transmission, through reception beamforming to the point of real-time data gridding capabilities, the complete data flow is controlled by a built-in data evaluation solution. The new ATLAS FANSWEEP 30 COASTAL is a well suited tool to satisfy actual and upcoming demands in highly efficient and most reliable survey operations.

Abstract:
The main aim of this work is research on the use of satellite positioning GNSS – RTK / RTN techniques to estimate the trajectory of a hydrographic boat. Modern hydrographic boat is the carrier of advanced bathymetry system, integral with GNSS positioning techniques. The key elements of the correct execution of the hydroacoustic survey are two elements: the height of the water surface and precise determination of the position in the moment of performing depth measurement. Integrated Bathymetric System (ZSB) is installed on a floating platform which is in constant motion. To obtain correct results of the hydroacoustic survey, it is necessary to know the precise (3D) position of the platform. In this paper the author presented his own research on the precise determination of accurate and reliable trajectory of a boat. The proposed method uses Real Time Kinematic (RTK) techniques of satellite positioning GNSS (Global Navigation Satellite Systems). The article presents examples of the results obtained during the research work at the largest Polish river.

Full text
Abstract:
A low-cost multicamera Unmanned Aircraft System (UAS) is used to simultaneously estimate open-coast topography and bathymetry from a single longitudinal coastal flight. The UAS combines nadir and oblique imagery to create a wide field of view (FOV), which enables collection of mobile, long dwell timeseries of the littoral zone suitable for structure-from motion (SfM), and wave speed inversion algorithms. Resultant digital surface models (DSMs) compare well with terrestrial topographic lidar and bathymetric survey data at Duck, NC, USA, with root-mean-square error (RMSE)/bias of 0.26/–0.05 and 0.34/–0.05 m, respectively. Bathymetric data from another flight at Virginia Beach, VA, USA, demonstrates successful comparison (RMSE/bias of 0.17/0.06 m) in a secondary environment. UAS-derived engineering data products, total volume profiles and shoreline position, were congruent with those calculated from traditional topo-bathymetric surveys at Duck. Capturing both topography and bathymetry within a single flight, the presented multicamera system is more efficient than data acquisition with a single camera UAS; this advantage grows for longer stretches of coastline (10 km). Efficiency increases further with an on-board Global Navigation Satellite System–Inertial Navigation System (GNSS-INS) to eliminate ground control point (GCP) placement. The Appendix reprocesses the Virginia Beach flight with the GNSS–INS input and no GCPs.
