Abstract: The road is a transportation infrastructure that is essential for humans. The road connects a community of people in a region with other regions, one important aspect for highway construction was securing the road from the water, either from rain or from a side-street drainage impact on the road surface damage. Bener Meriah district, a mountainous region with an altitude of 100 meters above sea level up to 2,500 meters, with a fairly high rainfall. Road conditions on the slopes and foothills affect the slope of the road longitudinal slope and drainage in the rainy season the road so much going drainage is not functioning properly. Water flows and puddles on the pavement as well as the water flows out of the drainage caused by slope which was great so happens scouring the drainage, plus more water falling from the slopes directly to the pavement without any treatment, for it was necessary to do research that aims to identify capacity of the existing road drainage network, knowing and planning network capacity as well as the road drainage slope drainage is needed so that the roads are not inundated by rain water discharge. The research was conducted on roads Pondok Baru - Permata on Sta.4 + 200 s / d Sta10 + 522. The method used in this research was the average algebra as well as to get a discharge plan and dimension using numerical equations rational modification with a system of trial and error, to come to the rain plan period of 5 years is 184 mm. Existing drainage conditions based on calculations obtained an average drainage discharge 1.52 m3 / sec and the discharge count 0.52 m3 / sec flow rate of water drainage on average at 7.54 m / sec speeds exceeding 1.5 license m / sec. Having calculated back then obtained an average discharge chute 0.519 m3 / sec and the discharge count 0,517 m3 / sec at the speed of average water flow of 1.31 m / sec, drainage on roads Pondok Baru - Permata diredesign necessary. Abstrak: Jalan merupakan infrastruktur transportasi yang sangat penting bagi manusia.

Abstract:
An ideal road infrastructure has a low cost for maintenance and better performance of the roads and drainage systems. The disintegrated maintenance system between the roads and drainage is the major cause of an increasing road maintenance cost. Therefore, this research aimed to investigate the impact of drainage towards roads in maintenance cost. This paper is located in Surakarta which was divided into eight catchment areas. The main variables of this paper are cost maintenance of drainage and roads, which were analyzed using regression. These variable data were obtained from the total cost per year allocated by Surakarta City Government on the urban drainage and local road maintenance budget from 2013 to 2017. The results showed that low drainage maintenance cost tended to result in high road maintenance cost.

Abstract:
The existing drainage system of roads proposed to manage the quantity of runoff from the road only, while the quality remains uncontrolled. In fact the pollutants and waste originated from the road surface contains hazardous substances. Sustainable drainage system (SUDS) concept offers various structures to solve both quantity and quality problems of surface runoff from roads. One of the potential drainage structure is filter drain or infiltration trench develope along the right side and left side of road. It could be developed by retrofitting the existing drainage channel of the road. The objective of this paper proposes the design model of road drainage based on the concept of a sustainable urban drainage system. The model consists of U-ditch channel, reservoir, an infiltration well. The bottom of U-ditch channel completed with a number of holes to make it porous. The channel filled with aggregate to filter the runoff from the road before flow down into the reservoir beneath. The water is then discharged to infiltration well. The model was developed based on rainfall data and other physical characteristics in Ambarawa City, Semarang Regency, Central Java.The channel dimensions and the depth of aggregate filter were designed base on runoff volume. The relationship among rainfall, runoff volume, area ratio, and drainage dimension are obtained. The results concept of sustainable road drainage is obtained in addressing the quality and quantity of rainwater.

Abstract:
Roads are the most widely used transportation infrastructure by the people of Indonesia to carry out daily activities, with the increasing flow of vehicles passing a road segment, it must be balanced by good pavement conditions. To achieve this balance, we need a design that is in accordance with the events in the field. In addition, to meet the good character of the road, it must be equipped with water channels or drainage. Because the drainage channel or water channel is one of the complementary buildings that must be on the road to drain water so that the road body remains dry. Drainage channel is one of the technical requirements of road infrastructure. The alarming condition can be seen on Jalan Ismail Harun, Percut Sei Tuan District, Deli Serdang Regency. One of the access roads connecting Deli Serdang and Medan City was badly damaged. The road was flooded with water so that the road surface condition was not visible. To overcome this, this research is needed in the form of a design / design of drainage dimensions on the road segment. The method used in designing the drainage dimensions is the Road Drainage Planning Guidelines Method Pd T-02-2006-B. The results of the drainage dimension design are the cross-sectional width (b) of 0.7 m, the cross-sectional height (h) of 0.35 m and the guard height (w) of 0.4 m.

Abstract:
An important aspect of the road structure strength and stability ensuring is the issue of subgrade favorable water-thermal regime providing during the service life. The article analyzes the results of research by scientists from different countries on the issues of taking into account the humidification regime and the arrangement of the drainage system on highways. One of the main design parameters of shallow transverse drainages is the distance between the drainage slots. The exact definition of this indicator determines the efficiency of water drainage from planar drainage and makes it possible to optimize the cost of drainage structures installation. In the presented work the questions of the existing normative base on climatological indicators definition and principles of shallow drainages calculation are generalized and tasks of researches on improvement and specification of distance between cross drainage apertures calculation method in such drainages are formulated. The authors propose a new solution to the problems. The developed method is based on the basic of non-uniform smooth-motion of a fluid in prismatic channels differential equation and the hypothesis of VI Chernomsky. The authors developed dependences to determine the distance between the transverse drainage slots in shallow drainages. The developed mathematical equations for the main parameters of transverse shallow drainage on characteristic sections of the highway adequately take into account the main factors influencing the process of moisture migration in the drainage layers and allow to solve problems of water-heat regulation of roads in a new aspect. The results of calculations of the distance between the transverse drainage slots, according to the proposed method, for the conditions of the first roadclimatic zone of Ukraine, the maximum total specific excess of water entering the drainage structure for the sand drainage layer with the value of filtration coefficient 4, 5 and 6 m / day are presented. The obtained data are compared with the calculation results according to the traditional method. Appropriate conclusions are made.

Abstract:
In this study a new method of locating culverts is presented with the composition of achieved discharge from hydrological analysis and simulated forest roads in RoadEng 3D simulator to improve drainage condition. Locating culverts was performed on a small scale (1:20 000, using GIS) and large scale (1:2 000, road geometric design simulator). The small-scale study regarding the achieved discharge from streams shows that the installation of some culverts is not necessary. The large-scale study also showed that the geometric design of forest road has a significant effect on locating culverts and its accuracy. To improve drainage conditions 6 culverts and 2 waterfronts taking into account the geometric design of forest road, hydrological conditions and appropriate intervals (155 m) have been proposed. No installation or lack of accuracy to find the best location of culverts may result in the occurrence of creep and landslide, so the cost of destruction would be several times higher than the cost of technical buildings construction.

Abstract:
Abstract Sungai Beringin Street is a road that has the status of a provincial road, as a connecting road between the capital city of the District of Tembilahan with other districts such as Batang Tuaka Subdistrict, Gaung Serka Children, Gaung and its surroundings. Jalan Sungai Beringin is one of the most densely populated areas of vehicle traffic experiencing flooding problems that regularly occur during the rainy season, because the condition of the drainage system is not well connected and there is no drainage channel on the road. Inundation will affect traffic for vehicles using the road to carry out daily activities, so that it can allow a greater disaster to harm the local community both property and life. According to Suripin, (2004; 7) drainage originating from English Drainage means to drain, drain, dispose of, or divert water. Drainage in the field of civil engineering, can be defined as a technical action to reduce excess water, both from rainwater, seepage, or excess irrigation water from an area / land, so that the function of the area / land is not disturbed. Drainage can also be interpreted as an effort to control the quality of groundwater in relation to salinity, so drainage involves not only surface water but also groundwater. Planning of drainage system for Parit 16 road with dimensions of channel height (h) 0.85 meters, channel width (b) 1.00 meters with slope of 0.04 and safety height of 0.65 meters while trench road 17 with high dimensions of the channel ( h) 0.95 meters, channel width (b) 1.00 meters with a slope of 0.04 and height of 0.69 meters construction of this drainage system in order to accommodate the rainwater discharge on the Beringin River which causes flood inundation during the rainy season . From the results of analysis of calculations, the total cost of the Budget Plan is obtained. The cost of constructing the ditch 16 drainage channel is = Rp. 3,219,594,000.00 and drainage ditch 17 drainage channel = Rp. 3,859,080,000.00. Abstrak Jalan Sungai Beringin adalah jalan yang berstatus jalan Propinsi, sebagai jalan penghubung antara Ibu Kota Kabupaten Kecamatan Tembilahan dengan Kecamatan lain seperti Kecamatan Batang Tuaka, Gaung Anak Serka, Gaung dan sekitarnya. Jalan Sungai Beringin merupakan salah satu wilayah jalan lalu lintas kendaraan yang cukup padat mengalami masalah banjir genangan air yang rutin terjadi pada saat musim hujan, dikarenakan kondisi sistem drainase belum terhubung dengan baik dan tidak adanya saluran drainase pada ruas jalan tersebut. Genangan akan mengangu lalu lintas bagi kendaraan yang mengunakan ruas jalan tersebut untuk melakukan aktivitas sehari-hari, maka dapat memungkinkan terjadi bencana yang lebih besar hingga merugikan masyarakat setempat baik harta benda maupun nyawa. Menurut Suripin, (2004; 7) drainase yang berasal dari bahasa Inggris Drainage mempunyai arti mengalirkan, menguras, membuang, atau mengalihkan air. Drainase dalam bidang teknik sipil, dapat didefinisikan sebagai suatu tindakan teknis untuk mengurangi kelebihan air, baik yang berasal dari air hujan, rembesan, maupun kelebihan air irigasi dari suatu kawasan/lahan, sehingga fungsi kawasan/lahan tidak terganggu. Drainase dapat juga diartikan sebagai usaha untuk mengontrol kualitas air tanah dalam kaitannya dengan salinitas, jadi drainase menyangkut tidak hanya air permukaan tapi juga air tanah. Perencanaan sistem drainase ruas jalan Parit 16 dengan dimensi tinggi saluran (h) 0,85 meter, lebar saluran (b) 1,00 meter dengan kemiringan 0,04 dan tinggi jagaan 0,65 meter sedangkan ruas jalan parit 17 dengan dimensi tinggi saluran (h) 0,95 meter, lebar saluran (b) 1,00 meter dengan kemiringan 0,04 dan tinggi jagaan 0,69 meter pembangunan sistem drainase ini agar dapat menampung debit air hujan di jalan Sungai Beringin yang menyebabkan banjir genangan pada saat musim hujan. Dari hasil analisa perhitungan maka diperoleh total biaya Rencana Anggaran Biaya pembangunan saluran drainase ruas jalan parit 16 sebesar = Rp. 3,219,594,000.00 dan saluran drainase ruas jalan parit 17 sebesar = Rp. 3,859,080,000.00.

Abstract:
Climate change is expected to lead to more frequent extreme precipitation events, floods and changes in frost/thawing cycles. The frequency of road closures and other incidents such as flooding, landslides and roads being washed away will probably increase. Stronger demands will be placed on the function of road drainage systems. The overall aim of this thesis was to produce scientifically well-founded suggestions on adaptation of road drainage systems to climate change involving more frequent floods. The work began by examining current practice for road drainage systems in Sweden and gathering experience from professionals working with various problems concerning surface and subsurface drainage systems. Various hydrological models were then used to calculate the runoff from a catchment adjacent to a road and estimate changes in peak discharge and total runoff resulting from simulated land use measures. According to these survey and hydrological modelling studies, adaptation of road drainage systems to climate change can be grouped into two categories: i) institutional adaptation; and ii) technical adaptation. The main approaches in institutional adaptation are to: i) raise the awareness of expected climate change and its impact on drainage systems in transport administration and relevant stakeholders; ii) include adaptation measures in the existing funding programme of the transport administration; and iii) develop an evaluation tool and action plans concerning existing road drainage systems. Technical adaptation will involve ensuring that road constructions are adapted to more frequent extreme precipitation events and responsive to changes in activities and land use in areas adjacent to roads. Changes in climate variables will have effects on watershed hydrological responses and consequently influence the amount of runoff reaching roads. There is a great need for tools such as hydrological models to assess impacts on discharge dynamics, including peak flows. Improved communication between road managers and local actors in the forestry and agriculture sectors can be a means to reduce the impacts of, e.g., clear-cutting or badly managed farmland ditches.

Abstract:
It is envisaged that flood plains will be put into more active usage to meet the increasing demands for road infrastructural development as well as relieve the pressure exerted on arable lands owing to infrastructural development activities. This is consequent upon the general shortfall in the availability of soils possessing the right engineering properties to carry infrastructures such as roads which consume large tracks of land. Expanding the global infrastructural base is inevitable due to the ever increasing human population and the need to meet their social, economic, political and transportation needs. However, owing to the prevailing environmental awareness campaigns fronted by different environmental agencies, there is the need to regulate and monitor the interaction of the processes involved in the provision of these needs with the limited resources as well as the environmental aftermath associated with such operations. The stabilization of flood plain soils for road embankment construction is envisaged to reduce the demand on the material resources required to build classical high embankments in flood prone areas as well as offer implied mitigating dimensions in the restoration of environmental integrity. This impliedly will reduce the use of traditionally unsustainable methods of soil stabilization such as, the excavation and importation of new materials, to a more robust system that will offer environmental friendliness amidst value engineering for better strength and durability results. The experimental processes involved the simulation of flooding scenarios in the laboratory, to monitor the strength and durability aspects of low-bearing-capacity soils (such as Lower Oxford Clay) stabilized with blended mixes of the traditional stabilizer of lime and the novel materials of lime and Ground Granulated Blastfumace Slag (GOBS) by-product combined. Preliminary investigations were carried out on the Lower Oxford Clay soil to establish the moisture and compaction requirements of the material. Different mix compositions were formulated by incrementally replacing the amount of lime in the system with GOBS. This was based on the premise that high stabilizer contents could offer better stabilization to flood susceptible geo-materials upon flooding. A high stabilizer level of 16% was therefore investigated. Regimes of different blending ratios were established as follows: 16%Lime-0%GGBS, 12%Lime-4%GGBS, 8%Lime-8%GGBS, 4%Lime-12%GGBS and 0%Lime-16%GGBS and tested at moisture contents of 23%, 28%, 33% and 38%. The two extremes 16%Lime-0%GGBS and 0%Lime-16GGBS were used as controls. A system of elimination based on strength criteria was employed, where only the 8%Lime- 8%GGBS and 4%Lime-12%GGBS mixtures were deemed fit to be investigated further to determine their resistance to challenging environmental factors of flooding. The test samples were cylindrical, measuring 50 mm in diameter and 100 mm long, and these were compacted using a static compaction apparatus to achieve Maximum Dry Density (MDD). Depending on the testing regime to be applied to a given specimen, a curing pattern was defined and samples were wrapped in cling film to minimise moisture losses. At the end of each curing period of 7, 14, 28, 56 and 90 days, one of the experimental procedures which ranged from Unconfined Compressive Strength, Water Absorption, Volume Stability, Permeability, Soaked Strength and Durability Index Assessment or Compressibility Assessment was carried out on the moist cured samples. Following these assessments, the 4%Lime-12%GGBS mix composition was appraised to have overall improved characteristics with the added benefit of reduced cost of material utilisation. Based on the available data, regression analyses were carried out and equations established for predicting the strength values of stabilized materials. Using these equations further extrapolations were made and the observable trends were those of the dependence of compressive strength on the age of moist curing and the compaction moisture contents at which samples were produced at given blended mixture. Cost-benefit-risk analysis was also carried out with a further cost annualisation of the capital and operational cost of a selected system. It is reassuring to learn that at replacement level of lime with GOBS of 4%Lime-12%GGBS it was possible to establish multi-binder mixtures that could be effectively used for sustainable construction in flood prone areas with enormous savings accruing from the possible higher strength and enhanced durability indices achievable over traditional unsustainable options of continued over-reliance on lime and Portland cement.

Abstract:
The main provisions of the methodology for calculating and designing a "green drainage system" of surface runoff from the road network of settlements that are not equipped with an underground drainage and treatment system are given. Requirements for the "green drainage system" of surface runoff from urban streets that are not equipped with an underground drainage system are formulated. The requirements include the treatment degree of surface runoff, filtration rate, comfort of the visual environment, safety and convenience for pedestrians and bicyclists, technologies of winter maintenance. The main pollutants of surface runoff for different categories of Russian streets are identified. The composition and depth of filtration media, its operating life, types of green plants are determined depending on the composition of pollutants, their typical concentrations, the collection area of surface runoff and the composition of native soils. Examples of the most effective design solutions for the "green drainage system" and treatment of surface runoff from the road network are given.

Abstract:
In most transit systems, rails are used as return conductors for the current from the vehicle to the electrical substations. If the rails are not fully insulated from the ground, some of this current would leak and become stray current, causing stray current corrosion on the rails and metal objects (such as pipelines) in the immediate area. It is very difficult to measure stray current directly, but stray currents can be calculated by measuring other parameters. Stray currents were measured on a 1.3 km section of tramway infrastructure in Ostrava. The potential between rail and earth was measured on the basis of the standard EN 50122-2, where two reference electrodes were placed at an appropriate distance from the tram track at three measuring points in the ground - the first point was located at the beginning of the section, the second in the half of the section and the last at the end of the section. Rail currents were measured at two measurement points - the first point at the beginning of the section and the second point at the end of the section. Using the rail-to-earth potential and the equation from the standard EN 50122-2:2011, the rail-to-earth conductance per length was calculated. The conductance per length was also calculated using Ohm's law, where the current difference is a difference between two measurement points. Since the results obtained using the standard and Ohm's law did not agree, a detailed analysis of the tram section was performed and electrical drainage was found. The drainage represents an electrical connection of the protected metal structure in the area of the tram track by a cable with stray current source. Through the drainage, the stray currents are directly returned to the rail. In this measurement section, the drainage has influenced the current difference between the measurement points - without drainage, this difference would be much smaller.

Abstract:
Construction materials need to be observed through a lifetime carbon footprint. Due to the high greenhouse gas emissions from cement production, the lack of natural raw materials such as sand, a significant increase of WBA and the problem of its disposal, there has been a serious disturbance of the ecosystem. Therefore, it is necessary to encourage the use of production processes that consume less materials and energy, use waste-free resources, and include full recycling at the end of the product’s life. One of the possible solutions is the use of locally available wood biomass ash as a substitute for cement or sand in concrete mixes for non-structural precast concrete products. To achieve this goal, the relevant mechanical and durability properties of concrete products - kerbs and drainage channels, were investigated by replacing cement or fine aggregate with 15% of WBA and comparing it to a reference mixture without WBA. For this study, 5 different types of WBAs were collected from biomass power plants in the Republic of Croatia. This paper presents the effects of WBAs on the mechanical properties and durability of concrete products, which represents a possible more environmentally friendly alternative for industrial waste recycling compared to existing waste management options.

Abstract:
Maintenance of roadside ditches is important to avoid localized flooding and premature failure of pavements. Scheduling effective preventative maintenance requires mapping of the ditch profile to identify areas requiring excavation of long-term sediment accumulation. High-resolution, high-quality point clouds collected by mobile LiDAR mapping systems (MLMS) provide an opportunity for effective monitoring of roadside ditches and performing hydrological analyses. This study evaluated the applicability of mobile LiDAR for mapping roadside ditches for slope and drainage analyses. The performance of alternative MLMS units was performed. These MLMS included an unmanned ground vehicle, an unmanned aerial vehicle, a portable backpack system along with its vehicle-mounted version, a medium-grade wheel-based system, and a high-grade wheel-based system. Point cloud from all the MLMS units were in agreement in the vertical direction within the ±3 cm range for solid surfaces, such as paved roads, and ±7 cm range for surfaces with vegetation. The portable backpack system that could be carried by a surveyor or mounted on a vehicle and was the most flexible MLMS. The report concludes that due to flexibility and cost effectiveness of the portable backpack system, it is the preferred platform for mapping roadside ditches, followed by the medium-grade wheel-based system. Furthermore, a framework for ditch line characterization is proposed and tested using datasets acquired by the medium-grade wheel-based and vehicle-mounted portable systems over a state highway. An existing ground filtering approach is modified to handle variations in point density of mobile LiDAR data. Hydrological analyses, including flow direction and flow accumulation, are applied to extract the drainage network from the digital terrain model (DTM). Cross-sectional/longitudinal profiles of the ditch are automatically extracted from LiDAR data and visualized in 3D point clouds and 2D images. The slope derived from the LiDAR data was found to be very close to highway cross slope design standards of 2% on driving lanes, 4% on shoulders, as well as 6-by-1 slope for ditch lines. Potential flooded regions are identified by detecting areas with no LiDAR return and a recall score of 54% and 92% was achieved by the medium-grade wheel-based and vehicle-mounted portable systems, respectively.

Perkins, Dustin. Invasive exotic plant monitoring at Fossil Butte National Monument: 2021 field season. Edited by Alice Wondrak Biel. National Park Service, September 2022. http://dx.doi.org/10.36967/2288496.

Abstract:
Invasive exotic plant (IEP) species are one of the biggest threats to natural ecosystem integrity and biodiversity, and controlling them is a high priority for the National Park Service. The Northern Colorado Plateau Network (NCPN) selected the early detection of IEPs as one of 11 monitoring protocols to be implemented as part of its long-term monitoring program. This report represents work completed during the 2021 field season at Fossil Butte National Monument (NM). From June 26 to 29, 2021, we recorded a total of 12 different priority IEP species during monitoring. A total of 763 priority IEP patches were recorded along 61.9 kilometers (38.5 mi) of 22 monitoring routes. Summer cypress (Bassia scoparia) was detected for the first time on monitoring routes along the Main Park Road. The highest densities of IEP patches were detected in several drainages and one trail: Sage Grouse Lek Drainage (32.7 patches/km), East Red Hill Drainage (19.4/km), Moose Bones Canyon (19.4/km), Main Park Road (19.0/km), West Fork Chicken Creek (17.6/km), Chicken Creek (15.0/km), Smallpox Creek (13.5/km) and the Historic Quarry Trail (11.1/km). The Fossil Butte Northwest, Wasatch Saddle, and North Dam Fork of Chicken Creek drainages were the only routes free of priority IEPs in 2021. Cheatgrass (Bromus tectorum), creeping foxtail (Alopecurus arundi-naceus), and Japanese brome (Bromus japonicus) were the most widespread species. Creeping foxtail continues to increase parkwide and along the Main Park Road and southern drainages. The two brome species have declined somewhat since 2018, but these species can fluctuate widely based on precipitation. Flixweed (Descurainia sophia), whitetop (Cardaria sp.), and quackgrass (Elymus repens) all appear to have declined since 2018 and their previous highs in earlier years. Control efforts by park staff are likely helping to prevent some IEP increases in the park. Network staff plan to return to Fossil Butte NM for an eighth round of monitoring in 2023.

Abstract:
Thurgood Canyon, located on White Sands Missile Range (WSMR), contains an alluvial fan that is bisected by a primary installation road and is in the proximity of sensitive fish habitats. This project was initiated to determine if and how sensitive fish habitats at the base of the fan are impacted by the existing drainage infrastructure and to assess the condition and sustainability of the existing transportation infrastructure. Findings show that the current drainage infrastructure maintains flow energy and sediment carrying capacity further down the fan than would occur in its absence. However, frequent to moderately rare (small to medium) flood events dissipate over 2 km from sensitive habitat, and overland flow and sediment do not reach the base of the fan. Controlled flow diversion is recommended upstream of the road to mitigate infrastructure or habitat impacts during very rare (very large) flood events. A comprehensive operation and management approach is presented to achieve sustainable transportation infrastructure and reduce the likelihood of impacts to the sensitive habitat.

Abstract:
With the industry foundation classes (IFC) building information modeling (BIM) standard (ISO 16739) being adopted by AASHTO as the national standard for modeling bridge and road infrastructure projects, there comes a great opportunity to upgrade the INDOT model development standard of roads and related assets to 2D+3D BIM. This upgrade complies with the national standard and creates a solid foundation for preserving accurate asset information for lifecycle data needs. This study reviewed the current modeling standards for drainage and pavement at different state DOTs and investigated the interoperability between state-of-the-art design modeling software and IFC. It was found that while the latest modeling software is capable of supporting interoperability with IFC, there remain gaps that must be addressed to achieve smooth interoperability for supporting life cycle asset data management. Specifically, the prevalent use of IfcBuildingElementProxy and IfcCourse led to a lack of differentiation in the use of IFC entities for the representations of different components, such as inlets, outfalls, conduits, and different concrete pavement layers. This, in turn, caused challenges in the quality assurance (QA) of IFC models and rendered the conventional model view definition (MVD)-based model checking insufficient. To address these gaps and push forward BIM for infrastructure at INDOT, efforts were made in this project to initially create model development instruction manuals that can serve as the foundation for further development and the eventual establish a consistent and comprehensive IFC-based modeling standards and protocols. In addition, automated object classification leveraging invariant signatures of architecture, engineering, and construction (AEC) objects was investigated. Correspondingly, a QA method and tool was developed to check and identify the different components in an IFC model. The developed tool achieved 91% accuracy on drainage and 100% accuracy in concrete pavement in its tested performance. These solutions aim to support the lifecycle management of INDOT transportation infrastructure projects using BIM and IFC.

Full text
Abstract:
Permafrost conditions in the Slave Geological province are not well understood. Thaw of permafrost and associated ground ice can reduce ground stability, which modifies terrain and drainage patterns and affects terrestrial and aquatic ecosystems. This presents critical challenges to northern resource development and societies where thaw of ice-rich permafrost negatively affects the integrity of ground-based infrastructure. In an effort to address this knowledge gap, this report presents a digital georeferenced database of landforms identified in permafrost terrain using high-resolution satellite imagery and provides information on geomorphic indicators of ground ice presence and thaw susceptibility. Digital georeferenced databases compiled from sedimentological and cryostratigraphic records are also provided. The landform database is focused on mapping within a 10 km-wide swath of land (8576 km2 area of interest) centred on the proposed corridors for the 773 km-long Slave Geological Province Corridor Project, NT, and the Grays Bay Road and Port Project, NU. The geomorphic features were classified and digitized using high-resolution (0.5 m) satellite imagery following an existing protocol, which was modified by using a very high-resolution (2 m) digital elevation model (DEM), and by including mapping criteria for additional features. A total of 1393 geomorphic features were mapped comprising 10 different types, which were categorized into 3 classes that include periglacial (1291), hydrological (88), and mass movement (14) features. Data from 254 geotechnical boreholes and 2243 granular deposits were compiled. Information from the compiled databases was analyzed with surficial geology information. Results indicate that the distributions and densities of mapped landforms varied substantially according to surficial geology. High ground ice contents may be quite common in glaciofluvial deposits where creep of frozen ground affects about 30% of eskers. And ground ice may be more extensive overall than the available geotechnical data indicate. Borehole and granular deposit data suggest that overburden thickness above bedrock was up to 25.5 m, and visible ground ice contents were generally between 10% and 30%, but were up to 60% in glacial blanket and glaciofluvial sediments.

The Northern Colorado Plateau Network (NCPN) selected the early detection of IEPs as one of 11 monitoring protocols to be implemented as part of its long-term monitoring program. This report represents work completed during the 2021 field season at Golden Spike National Historical Park (NHP). On June 24–25, 2021, we recorded a total of six priority IEP species during monitoring at the park. A total of 191 priority IEP patches were detected along 20 kilometers (12.4 miles) of 13 monitoring routes that covered all major roads, trails, and riparian areas. Three additional IEP species were recorded only in transects. The highest densities of IEP patches were recorded along the Hydro 1 and Last Cut drainages, followed by the Residence Service Road, East Tour Road, and Visitor Center Sidewalk Area. Rush skeletonweed (Chondrilla juncea) was the most prevalent priority species, representing 46% of all recorded patches. Field bindweed (Convolvulus arvensis) and Scotch thistle (Onopordum acanthium) constituted most other patches. The notable absence of Russian knapweed (Centaurea repens) represents past control efforts for this species. When compared to 2018, there was a dramatic increase in the number of IEP patches in 2021, driven by rush skeletonweed and field bindweed. More-widespread species monitored in transects were still common, with cheatgrass (Bromus tectorum), crested wheatgrass (Agropyron cristatum), and tumble mustard (Sisymbrium altissimum) present in 84%, 45%, and 36% of all transects, respectively. The network plans to return to Golden Spike NHP for an eighth year of monitoring in 2023.
