Abstract:
Floods and erosion often cause landslides of riverbanks and induce problems such as river blockage, shift of river center, or flooding from rising riverbeds. Instrumentation and monitoring are often used to explore landslide and erosion behavior of riverbanks. Therefore, this study identified landslide types and characteristics of their seismic signals due to toe erosion of riverbanks through riverbank models with various instrumentation sensors in a laboratory flume. To induce landslides in the riverbank model, a test was set up for water to flow through the toe of the riverbank model. Seismic signals of each landslide event were measured during the tests with accelerometers. Nonpolarized electrodes were installed for observing the self-potential changes during the test. Water content and pore water pressure gauges were installed in the riverbank model. In addition, water levels were recorded. The Hilbert–Huang transform method was used to analyze the characteristics of seismic signals caused by water flow and riverbank landslides. Time points, landslide frequency distributions, and the characteristics of several landslide events in the riverbank models were estimated using the seismic signals. This study identified three types of landslides: single, intermittent, and successive. Moreover, changes in self-potential signals, pore water pressure, and water content during the tests were examined and were found to correspond to the landslide process of the riverbank model.

Abstract:
Ciliwung riverbank has been affected by settlement occupation. Both concrete and another retaining wall system have been built to avoid flood and erosion to the settlement that has existed adjacent to the river. Built environment as human disturbance can trigger the change of species richness of ground vegetation in the Ciliwung riverbank of Bogor City. The research objective is to study the difference of ground vegetation biodiversity in three different types of riverbank based on its condition: natural, semi-natural, and constructed riverbanks. Point method and photographic sampling are used. Five replications of a square metre plot at three transects were placed at four sites sampling along 250 m each from the three different types of riverbank. Images of the plots are trained using sample point to overcome the difficulties in the field observation and statistical analysis. The result discovered that species richness in the natural riverbank is significantly higher than in semi-natural and constructed riverbank. Yet, no significance of species richness is shown between semi-natural and constructed riverbank. Total species of ground vegetation that we found were 55 species. Each different type of riverbank has its own highest species coverage: Asystasia nemorum (55.00%) in the natural riverbank, Pilea nummulariifolia (33.07%) in the semi-natural riverbank, and Pogonatherum crinitum (52.80%) in the constructed riverbank. The study concluded that the construction in the riverbank largely altered the biodiversity of ground vegetation in the urban riverbank. The outcomes suggest that the remnant of natural riverbank in the urban landscape should be highly protected from urban development to preserve its biodiversity. Also, species found could be potentially developed as landscape plants to support urban river planning, design, and management.

Abstract:
The riverbank is an effective component of the city-river interconnection, and any damage that occurs to it affects its natural structure and particularly its ecological values. Most of these problems are diagnosable and observable in the riverside space, and many studies have focused on them. The emergence of these problems may appear in varying proportions in the riverbank environment depending on the type of human intervention, both in urban and non-urban spaces, which may have a negative impact on the riverbank space. In light of this, studies have been directed towards exploring different ecological strategies that should be applied on the urban riverbank space, which work in an integrated manner with many other values to restore the natural characteristics of landscape and riverbank space and reduce the impact of negative human intervention in them. The main research problem is defined in the loss of the ecological value of riverbanks in cities in general and Baghdad city in particular, and the lack of knowledge concerning the ecological strategies in riverbanks on the planning and design levels. The main objective of the research was thus to draw the theoretical framework that extracts the strategies and indicators of the landscape ecology.The theoretical framework was then applied to the edge of the Tigris River in Baghdad (as a case study), that resembles the area and park of Abu Nuwas region in Baghdad, with the aim of further diagnosing the reality of the riverbank and the extent to which ecological strategies can be applied.The results of the research in both its theoretical and practical aspects have revealed a clear approach to ecological strategies that achieve riverbank ecology and the development of specific mechanisms to provide a safe and effective river environment that accommodates various events and uses in the river bank, and enhances public awareness of its importance

Abstract:
The increasing number of extreme climate events has impacted the operation of reservoirs, resulting in drastic changes in flow releases from reservoirs. Consequently, downstream riverbanks have experienced more rapid and frequent changes of the river water surface elevation (WSE). These changes in the WSE affect pore water pressures in riverbanks, directly influencing slope stability. This study presents an analysis of seepage and slope stability for riverbanks under the influence of steady-state, drawdown, and peaking operations of the Roanoke Rapids Hydropower dam on the lower Roanoke River, North Carolina, USA. Although the riverbanks were found to be stable under all the discharge conditions considered, which indicates that normal operations of the reservoir have no adverse effects on riverbank stability, the factor of safety decreases as the WSE decreases. When the role of fluvial erosion is considered, riverbank stability is found to reduce. Drawdown and fluctuation also decrease the safety factor, though the rate of the decrease depends more on the hydraulic conductivity of the soils rather than the discharge pattern.

Abstract:
The hypotheses that litter deposition on riverbanks would depend on riverbank features and that litter mass would affect riverbank vegetation were tested by sampling vegetation, litter, and soil along a seventh-order stretch of the unregulated Vindel River in northern Sweden. Sampling was carried out within a horizontal litter gradient at the top of the riverbank where most of the litter deposition occurs. The amount of leaf litter left on the riverbank after flooding was significantly correlated (P < 0.05) with soil organic matter. In contrast, wood litter mass and total litter mass were not correlated (P > 0.05) with riverbank features such as soil organic matter, riverbank slope, or stem density. Species richness, species diversity, and the proportions of stemmed and nonstemmed species showed quadratic relationships (P < 0.05) with leaf litter mass, whereas ground vegetation cover decreased monotonically (P < 0.05) with increasing leaf litter mass. Tall, stemmed species were most frequent at eroded sites with low amounts of leaf litter and at sites where leaf litter had accumulated. In contrast, the highest proportion of low-growing species was found at sites with intermediate leaf litter masses. Community characteristics such as species richness, species diversity, and the proportions of stemmed and nonstemmed species (but not ground vegetation cover) were less strongly correlated with wood litter mass and total litter mass. Linear equations explained about half of the variation in ground vegetation cover along gradients of wood and total litter masses. Density and richness of seeds increased with increasing litter mass. We discuss the litter effects in terms of productivity and disturbance and conclude that flooding in pristine rivers may exert a considerable influence on riverbank vegetation as a result of litter displacement.

Abstract:
This article attempts to understand how the settlement layout of riverbank communities, with the case in the Ogan Malay community in South Sumatra province. This article is based on empirical reality in which the community tends to always live on the riverbank, especially the riverbank, with raging water. For the Ogan Malay community, the settlement is an area consisting of villages as dwellings, but also include agricultural areas (fields, fields, and gardens) and other supporting areas, as a source of life. As a riverbank community, the river has always been central in determining the layout of elements of its settlements, thus creating a unique settlement layout pattern. This article is the result of ethnographic (anthropological) research conducted by the author in April - June 2019. Data were collected through depth interviews with indigenous leaders and local communities in the location, as well as through participant observation of life activities in the research field. The results showed that living on the riverbanks is not arbitrary, but based on the community's knowledge system on the river environment itself. This knowledge creates a unique pattern of community settlement layout, where the river has always been central in the preparation of layout planning.

Abstract:
Protecting against riverbank erosion along the world’s largest rivers is challenging. The Bangladesh Delta, bisected by the Brahmaputra River (also called the Jamuna River), is rife with complexity. Here, an emerging middle-income country with the world’s highest population density coexists with the world’s most unpredictable and largest braided, sand-bed river. Bangladesh has struggled over decades to protect against the onslaught of a continuously widening river corridor. Many of the principles implemented successfully in other parts of the world failed in Bangladesh. To this end, Bangladesh embarked on intensive knowledge-based developments and piloted new technologies. After two decades, successful, sustainable, low-cost riverbank protection technology was developed, suitable for the challenging river conditions. It was necessary to accept that no construction is permanent in this morphologically dynamic environment. What was initially born out of fund shortages became a cost-effective, systematic and adaptive approach to riverbank protection using improved knowledge, new materials, and new techniques, in the form of geobag revetments. This article provides an overview of the challenges faced when attempting to stabilize the riverbanks of the mighty rivers of Bangladesh. An overview of the construction of the major bridge crossings as well as riverbank protection schemes is detailed. Finally, a summary of lessons learned concludes the impressive progress made.

Abstract:
The dominant mechanism of riverbank cantilever failure is soil erosion of the bank toe and near bank zone. This paper demonstrates that the shape of the riverbank cantilever failure depends on the properties of the soil and the fluctuation of the river water level (RWL). With a stable RWL, a riverbank with higher resistance force leads to failure with larger and deeper overhang erosion width. When RWL rises, a less cohesive soil bank will be eroded over a larger width and riverbank failure will occur earlier. With a low rate of rising RWL, riverbank failure may happen in a type of mass failure. With a high rate of rising RWL, a riverbank will fail in a type of overhang riverbank failure, with the soil erosion rate being the main affected factor.

Abstract:
Groundwater flow and microorganism (Cryptosporidium parvum, Escherichia coli and MS2) transport was simulated for a Riverbank Filtration (RBF) System in the Rio Grande de Manati region of Puerto Rico. MODFLOW 2000, a 3D saturated flow model, was used to simulate groundwater flow from the river to the wells in the riverbank. RT3D, a multi-species reactive model, was used to simulate microorganism transport. Both models required several parameters: (i) hydro-geological parameters were taken from previous research done in the study area, (ii) transport parameters (attachment coefficient and linear partitioning coefficient) were estimated based on sticking efficiency values reported in the literature. Colloid Filtration Theory was used for the estimation of the transport parameters. From the estimated parameters it was determined that microorganisms would show greater mass transfer from the aqueous to the solid phase at lower porosities. A 3-D grid was built to represent the study area. Groundwater flow output from MODFLOW 2000 showed a discrepancy of only 0.08% between inflow and outflow. MODFLOW 2000 generated inflow and outflow values matched values obtained in an earlier study at the same site, using MODFLOW 96. This indicated that the model's mass balance calculations were very good. RT3D used the flow results, obtained with MODFLOW 2000, to build the transport model. The river water microorganism load was set to a constant level of 100 microorganisms/L. On the basis of a 1000-days' simulation for C. parvum and E. coli, it was shown that the RBF system could provide safer water to the Rio Grande de Manati region. However, the virus analogue MS2 would reach the well after 900 days. Simulations also demonstrated that C. parvum's removal would be more effective, compared to that of E. coli or MS2. Four different scenarios — varying aquifer porosity, pumping rates, number of wells, and intermittent pumping — were simulated to evaluate thei
L'écoulement d'eaux souterraines et le transport de microorganismes (Cryptosporidium parvum, Escherichia coli and MS2) furent simulés pour un système de filtration de berge (FDB) situé dans la région de Manati de Rio Grande, au Porto Rico. Le modèle tridimensionnel d'écoulement en milieu saturé MODFLOW servit à simuler le ruissellement souterrain allant de la rivière vers des puits creusés dans la berge. RT3D, un modèle réactif plurispécifique servit à simuler le transport de microorganismes. Ensemble, les deux modèles exigèrent plusieurs paramètres: (i) les paramètres hydrogéologiques provinrent d'une étude précédente au même site, (ii) les paramètres de transport (coefficients d'attachement et de partitionnement linéaire) furent basés sur des valeurs d'efficacité d'adhésion rapportées dans la littérature. La théorie de filtration des colloïdes servit a l'évaluation des paramètres de transport. À partir de ces paramètres on peut prévoir qu'à des porosités moins élevées les microorganismes montreront un transfert de masse plus élevée entre la phase aqueuse et solide. Une grille tridimensionnelle fut établie pour représenter le secteur d'étude. Avec MODFLOW 2000, une différence de 0.08% exista entre l'apport et la sortie d'eaux de ruissellement souterraines. Les apports et sorties d'eau prédites par MODFLOW 2000 concordèrent très bien avec ceux obtenus lors d'une étude préalable au même site, indiquant l'exactitude des calculs de bilan massique du modèle. RT3D fonda son modèle de transport sur les valeurs de ruissellement souterrain calculé par MODFLOW. La charge microbienne de l'eau riveraine fut établie à un niveau constant de 100 microorganismes/L d'eau. Une simulation de 1000 jours pour C. parvum and E. coli, montra qu'un système FDB pouvait fournir une eau plus saine à région de Rio Grande de Manati. Cependant, l'analogue de virus, MS2, se rendrait au puits après 900 jours. Les simulations démo

Abstract:
This thesis for the first time reports the fate and behaviour of herbicides mecoprop (MCPP) and isoproturon (IPU) in the hyporheic zone of a river bank. Two laboratory studies based on fixed-bed circulation and 14Crespirometry were developed to investigate the attenuation of the two herbicides in riverbank filtration (RBF), a means of pre-treatment of drinking water obtained from bank-side boreholes. The first laboratory study investigated the sorption and biodegradation of MCPP and IPU (100 μg L-1) in a river water (RW)-riverbed sediment (RS) system with materials obtained from a site on the River Thames at Gatehampton, England. Using a fixed-bed circulation method, approximately 18-20 % of the herbicides were removed by sorption, with the remainder removed by a high rate of biodegradation during 14 circulating days. The RS-borne microorganisms played a primary role in the biodegradation process of these herbicides, while the RW-borne microorganisms contributed very little. In addition, after a period of incubation (by 18 circulation days with IPU) the RS-borne microorganisms were able to immediately mineralise 14C-IPU (29.4 % 14CO2) while the RW-borne microorganisms were not competent to do so (1.6 % 14CO2). The second laboratory study investigated catabolic insights into IPU degradation in river water (RW), groundwater (GW) and riverbed sediment (RS). Very low maximum levels of mineralisation of IPU were observed in RW (0.4 % 14CO2) and GW (1.2 % 14CO2) while very high maximum level of mineralisation of IPU was obtained in RS (14.5 % 14CO2). Furthermore, the catabolic competence with respect to IPU was enhanced with increasing the IPU-dosed concentrations (ranging 1 – 100 μg L-1) in RS microcosm. By plotting the maximum mineralisation levels versus the residual IPU concentration (after various periods of incubation), a logarithm linear relation between the maximum mineralisation levels and IPU concentrations was obtained. This relationship suggested that higher mineralisation levels are achieved for higher IPU concentrations. Nonetheless, the catabolic activity not only was not significantly enhanced (p > 0.05) after a period of incubation (0 – 10 days) but also was greatly decreased (p < 0.05) after 30 incubation days. Based upon the experimental results, to remove the herbicides from 1 L of RW contaminated with MCPP and IPU (up to 100 μg L-1), a required volume of RS (bulk density of 1.25 ± 0.02 g cm-1 and porosity of 50.6 %) was determined to be 0.027 m3. Extent in a RBF context, it is suggested that a bank-side borehole with a capacity of 16 x 106 L day-1 and 25 % river-fed water could be protected from the river-borne herbicide pollution (up to 100 μg L-1) if the borehole is located at a minimum distance (path length) of 400 m from the river with the thickness of a RS layer to be 6 m. Collectively, the herbicides MCPP and IPU were completely degraded in a hyporheic zone of a river bank. Microorganisms originated from RS played a pivotal role in the degradation. This demonstrated that RBF is potentially a highly efficient pre-treatment method which can totally remove herbicide pollution in river. Hence, bank-side boreholes which are mainly or partly fed by induced RW may be benefit from this natural attenuation process.

Abstract:
Morphological changes along several channels have raised concerns in the Province of Manitoba. This thesis presents a comprehensive study of fluvial morphological processes in open channels. Due to the recent concerns in the Province of Manitoba, the study mainly focused on the Red River in the city of Winnipeg, and two diversion channels in northern Manitoba. Morphodynamic conditions of these channels have become more complicated due to the cohesive nature of the channels bed and bank material and significant effects of subaerial processes. Several field measurement techniques, experimental setups, and numerical models were used to gain a better understanding of these complicated processes within the study reaches. Field measurements include soil sampling, water sampling, hydrometric surveys using an ADCP; the experimental setup includes several standard soil properties tests as well as an erosion measurement test; numerical modelling includes hydrodynamic and thermal modelling to quantify applied shear stress and seasonal freeze-thaw processes. Moreover, the effect of deposition processes on the final geomorphology of the study areas is discussed.

Abstract:
This study was designed to test the hypothesis that riverbank erosion processes altered with increasing distance from a river source. The River Swale, northern England, was monitored at nine sites throughout its 109-km length, from December 1995 – March 1998. Erosion pins, bank-edge surveying, and Photo-Electronic Erosion Pins (PEEPs) were used to determine rates and timings of erosion. The rates were compared against a range of environmental variables based on temperature, river stage, and precipitation at 14-day intervals for erosion pins and 15-minute intervals for PEEPs. This allowed processes of erosion to be inferred. Catchment erosion rates were modelled using quadratic equations, simulating a mid-basin peak of 3.58 m a\(^{-1}\). Rates of erosion were low upstream, 0.07 m a\(^{-1}\), and also downstream, 0.12 m a\(^{-1}\). Subaerial processes, especially frost action, dominated upstream. Fluvial entrainment was most influential mid-catchment. Mass failures were most efficient downstream, but were more frequent mid-catchment. Piping, sapping and cantilever failures did not follow the same trends and were modelled separately. The length of the erosion season increased downstream as the number of active processes increased.

ENGLISH ABSTRACT: Groynes are hydraulic structures typically constructed from gabions to extend from the outer bank of a river channel into the main flow. The principal uses for groynes are as river training structures, and to protect the riverbank from erosion. This is done by deflecting the current away from the riverbanks, dissipating energy and creating lower flow velocity zones, reducing the effects of erosion. Groynes have been used extensively in the Western Cape since the early 1990s as a means to protect agricultural lands. There is, however an absence of published manuals for the design of groynes around bends as a means of riverbank protection. This study was done to better understand the flow, scour and sediment deposition patterns associated with implementing a series of groynes around a bend. A physical model of a typical sinusoidal South African river was constructed in the Hydraulics Laboratory at the University of Stellenbosch. The model consisted of two succesive 90˚ bends to best simulate erosion patterns. Different layout designs for a series of groynes were tested to determine the optimal design for the given situation in terms of the projection lengths of the groynes, the spacing between the groynes as a factor of the projection length, and the orientation of the groynes with regard to the oncoming flow. An integrated software package, that was developed at the National Centre for Computational Hydroscience and Engineering, at the University of Mississippi, named CCHE2D was used to simulate the physical model numerically. The model was calibrated by adjusting the Manning‟s n value of the sediment, and the normal tailwater depth was calculated and used for the physical and numerical models. The flow rate used during the physical model experiments was also used for the numerical model. The model was validated by comparing scour depths obtained from the physical model to the resulting depth in the hydrodynamic model. From the results obtained from the physical and numerical models, it was found that groynes with a perpendicular orientation to the direction of the oncoming flow were optimal. Groynes with an upstream orientation resulted in excessive scour around the nose of the groynes, while recirculating flow patterns occurred at a velocity which caused bank failure. Groynes with a downstream orientation created very little recirculation of flow, resulting in less scour protection for the outer bank than found for groynes with perpendicular orientation. Finally, the optimal design was identified as a perpendicular groyne orientation with a projection length L and a spacing of 3.5 xL. For the given design, eddy currents covered the entire area between consecutive groynes, causing low flow zones near the outer banks, promoting sediment deposition and decreasing the potential for scour. Recommendations for further studies include the investigation of the effects of different bend radii, the sediment size, as well as various channel widths, flow rates and river slopes. The use of a three-dimensional hydrodynamic model would also be advantageous in order to better understand the flow and scour mechanics associated with different designs.
AFRIKAANSE OPSOMMING: Groynes is hidrouliese strukture, tipies gebou uit skanskorwe in Suid Afrika, wat vanaf die buiteoewer van 'n rivier strek na die hoofkanaal. Groynes word hoofsaaklik aangewend as rigmure in riviere en om rivieroewers te beskerm teen erosie. Erosiebeskerming word geskep deur vloei weg te deflekteer van die rivieroewer en energie te dissipeer. Sodoende vorm areas met lae vloeisnelhede naby die oewer wat die potensiaal vir erosie verminder. Groynes is sedert die vroeë 1990s in die Wes-Kaap gebruik as 'n manier om landbougrond teen erosie te beskerm. Daar is egter 'n tekort aan gepubliseerde ontwerpriglyne vir die gebruik van groynes vir erosiebeskeriming in riviere. Hierdie studie is gedoen om die vloei-, uitskuringsen sediment neersettingspatrone, geassossiëer met die implementering van groynes, te ondersoek. 'n Fisiese model van 'n tipiese kronkelende Suid-Afrikaanse rivier is gebou in die Hidrouliese Laboratorium by die Universiteit van Stellenbosch. Die model bestaan uit twee opeenvolgende 90˚ draaie om die erosie-patrone te simuleer. Verskillende uitlegte vir 'n reeks groynes is getoets om die optimale ontwerp vas te stel in terme die projeksielengte van die groynes, die spasiëring tussen opeenvolgende groynes as 'n faktor van die projeksielengte en die oriëntasie van die groynes ten opsigte van die aankomende vloeirigting. 'n Geïntegreerde sagteware pakket wat ontwikkel is by die “National Centre for Computational Hydroscience and Engineering”, by die Universiteit van Mississippi, genaamd CCHE2D is gebruik om die fisiese eksperimente numeries te simuleer. Die model is gekalibreer deur die Manning n waarde van die sediment aan te pas, die stroomaf waterdiepte wat bereken is, en die vloeitempo wat waargeneem is tydens die fisiese eksperimente. Die model is bekragtig deur uitskuurdieptes van die fisiese- en hidrodinamiese modelle te vergelyk. Vanuit die resultate wat verkry is in die fisiese- en numeriese modelle, is daar gevind dat groynes met 'n loodregte oriëntasie met betrekking tot die aankomende vloei optimaal is. Daar is gevind dat groynes met 'n stroomop oriëntasie oormatige uitskuring rondom die neus van die groynes ondervind, terwyl hersirkulasie van vloei teen 'n hoë snelheid plaasvind, wat erosie van die oewer tot gevolg het. Groynes met 'n oriëntasie na die stroomaf kant het baie min hersirkulasie van vloei tot gevolg gehad, wat tot minder erosiebeskerming van die buitebank gelei het. Die optimale ontwerp is geïdentifiseer as groynes met loodregte oriëntasie, 'n projeksielengte van 0.675 m en 'n spasiëring van 3.5 keer die projeksielengte. Vir die gegewe ontwerp is werwelstrome gevind wat die hele area tussen opeenvolgende groynes dek, wat area van lae vloei sones veroorsaak naby die oewer, wat sediment deponering bevorder en die potensiaal vir uitskuring verminder. Aanbeveling vir verdere studies sluit die studie van die effekte van verskillende draai radiusse en die sediment-grootte in, sowel as verskillende kanaalbreedtes, vloeie en rivierhellings. Die gebruik van 'n drie-dimensionele hidrodinamiese model sal ook voordelig wees om die betrokke vloei- en uitskuringspatrone rakende verskillende ontwerpe beter te verstaan.

Abstract:
Erosion of the riverbank is one of the main issues that affect the oil lines in the world. Several studies, developed by the authors of this paper, in different basins of the country, identified the most common processes of instability and erosion of riverbanks in the affected areas. Concerning the characteristics of the problem, several alternatives have been considered to reduce the erosion rate and give priority to the mitigation of geomorphic processes and the stability of agricultural soils adjacent to the riverbank. The general goal of this article is to present several case studies and analytical tools that will allow estimating and evaluating the processes of lateral migration and undermining of the river-bed in the design of river crossing and outline of oil pipelines, in general. The experience of these authors in regards to erosion issues has allowed identifying the contribution of deposits suspended from the banks and that can be controlled combining stabilizing techniques according to the affected area. Usually, the lower half of the slope that is exposed to high shearing forces has to be protected through the use of strong and durable materials while the rest of the slope can be protected with native vegetation. Finally, the analytical alternatives presented by mathematical modeling are employed to predict hydraulic and mechanical effects from which can be exposed to margins in the construction stage and operation of the oil pipeline.

Abstract:
The orientation of constructed levee embankments relative to alluvial swales is a useful measure for identifying regions susceptible to backward erosion piping (BEP). This research was conducted to create an automated, efficient process to classify patterns and orientations of swales within the Lower Mississippi Valley (LMV) to support levee risk assessments. Two machine learning algorithms are used to train the classification models: a convolutional neural network and a U-net. The resulting workflow can identify linear topographic features but is unable to reliably differentiate swales from other features, such as the levee structure and riverbanks. Further tuning of training data or manual identification of regions of interest could yield significantly better results. The workflow also provides an orientation to each linear feature to support subsequent analyses of position relative to levee alignments. While the individual models fall short of immediate applicability, the procedure provides a feasible, automated scheme to assist in swale classification and characterization within mature alluvial valley systems similar to LMV.
