Watershed Ecological Environmental Development and Management using Remote Sensing and GIS: A Case Study in Nu River, Southwest China

The suspended sediment concentration (SSC) data are vital for assessing the impacts of human activities on soil erosion, maintaining the river channel navigation, prolonging the water reservoir life-span, eliminating the catastrophic events such as floods, and understanding the water quality.

However, most of the world’s rivers have not been gauged, and hence stream suspended sediment data are not readily available; the measurements have been stopped for most of the rivers that have been gauged. In order to estimate SSC effectively in the data-scarce areas, two methods - the rating curve method and the remote sensing method will be studied in the selected study areas - the Pearl River, the Mekong River and the Upper and Middle Yangtze River in the proposed research.
