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)

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...
Sediment buried in Oregon Coast Range points to a frosty past
Sediment buried Oregon Coast Range points frosty past
2015/12/7
Lush greenery rich in Douglas fir and hemlock trees covers the Triangle Lake valley of the Oregon Coast Range. Today, however, geologists across the country are more focused on sediment samples dating...
Operational remote sensing mapping of estuarine suspended sediment concentrations (ORMES)

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...
AN APPROACH TO QUANTIFY SEDIMENT YIELD IN VAST AREAS
Watershed Sediment Yield Index (SYI) Remote Sensing Technology
2015/8/17
Loss of fertile soil by erosion is undoubtedly much higher than weathering and soil formation. A
number of studies on estimation of sediment yield have been conducted and many such studies will be p...
Assessment of Spatial Patterns of Sediment Transport and Delivery for Soil and Water Conservation Programs
off-site soil erosion soil erosion deposition model
2015/8/14
Soil erosion has tremendous impacts on most river systems throughout the United States. Such non-point pollution results from land-use and agricultural practices and leads to sedimentation downstream,...
Linking Sediment Transport and Stratigraphy on the Continental Shelf
Continental Shelf Transport and Stratigraphy
2015/8/13
The goal of the shelf sediment dynamics component of STRATAFORM is to link sediment transport processes active on the continental shelf to the formation and preservation of event beds in shelf sedimen...
Estimation of useful life of a reservoir using sediment trap efficiency

Precision echo sounder surveys of bathymetry and sediment thickness of Lee Creek Reservoir and Lake Shepherd Springs (northwest Arkansas) were combined with Geographic Information Systems (GIS) analys...
Estimating Spatial Sediment Delivery Ratio on a Large Rural Catchment
soil erosion sediment yield sediment delivery ratio modelling
2015/8/11
Soil erosion and sediment yield from catchments are key limitations to achieving sustainable land use and maintaining water quality in streams, lakes and other water bodies. Controlling sediment loadi...
A Spatially Distributed Event-Based Model to Predict Sediment Yield
Runoff sediment yield Geographic Information System GIS remote sensing watershed event-based
2015/8/11
A study has been conducted in three sub-watersheds to model the spatial distribution of runoff and sediment yield. The basic structure of the model includes generation of runoff using SCS curve number...
Estimating sediment yield using Agricultural Non-Point Sources (AGNPS) model: The effects of slope information from different GIS softwares
