4D-SFM PHOTOGRAMMETRY FOR MONITORING SEDIMENT DYNAMICS IN A DEBRIS-FLOW CATCHMENT: SOFTWARE TESTING AND RESULTS COMPARISON
4D-SfM Photogrammetry Sediment dynamics monitoring Software comparison Debris flow hazard
2018/6/4
In recent years, the combination of Structure-from-Motion (SfM) algorithms and UAV-based aerial images has revolutionised 3D topographic surveys for natural environment monitoring, offering low-cost, ...
SIMULATION OF WATER SOIL EROSION EFFECTS ON SEDIMENT DELIVERY TO DOBCZYCE RESERVOIR
Geographic Information Science Soil Erosion Water Quality Spatial Modeling Sediment Yield RUSLE Sediment Delivering Ratio
2015/12/28
Synoptic information on suspended matter inflow into reservoirs is important because of the potential storage capacity reduction and water contamination. Such prognosis is difficult to obtain only fro...
USING TM IMAGE TO ESTIMATE THE QUANTITY OF SAND SEDIMENT IN POYANG LAKE:A CASE IN NANJI XIANG VILAGE
TM Image Sand Sediment Poyang Lake Eco-environment
2015/12/28
In this thesis, we build a relationship between Remote Sensing information and water depth to calculate and analyze the elevation of the riverbed. Combining with the water level elevation data, we can...
ASSESSMENT OF THE SENSORS MODIS/TERRA AND WFI/CBERS-2 FOR THE AMAZON RIVER SUSPENDED SEDIMENT MONITORING
suspended sediment coastal processes WFI/CBERS-2
2015/12/28
Suspended sediment load plays an important role in coastal processes. They can be used as a proxy for water quality variables such as turbidity, pollution and primary production. The large spatial and...
RIVER SEDIMENT MONITORING USING REMOTE SENSING AND GIS (CASE STUDY KARAJ WATERSHED)
GIS RS Monitoring Karaj Watershade Envi
2016/1/18
Whereas the tank volume and dehydrating digits from kinds of tanks are depended on repository sludge, so calculating the sediments is so important in tank planning and hydraulic structures. We are wor...
Operational remote sensing mapping of estuarine suspended sediment concentrations (ORMES)
hyperspectral Suspended Matter Scheldt
2015/9/2
The aim of the ORMES project is to develop a simple and robust procedure for near surface sediment concentration
mapping from remote sensing data, both airborne and satellite borne. The ORMES project...
Study on Watershed Analysis and Sediment Regime in The Swalik Region of Nepal
GIS Landsat Geomorphology Floods Analysis
2015/7/7
Wide spread damage due to floods is one of the very common water induced natural disasters in Nepal that account for heavy losses
during the monsoon period every year. Perennial rivers that flow thro...
Coseismic sediment deformation during the 1989 Loma Prieta earthquake
Coseismic sediment deformation Loma Prieta earthquake
2015/7/1
Leveling surveys, geodolyte, Global Positioning System (GPS), and very long interferometry surveys had been used to estimate the coseismic ground displacements during the MS 7.1, 17 October 1989 Loma ...
Estimating inelastic sediment deformation from local site response simulations
Coseismic sediment deformation Local site response Plasticity Seismicity Strong ground motion
2015/7/1
Significant insight into the dynamic local site response of a horizontally layered sediment deposit to seismic excitation can be gained from numerical simulations. In this paper we use a nonlinear loc...
