evaluation of sediment yield in watershed scale is considered so important for implementation of soil conservation, watershed management, environment, dam construction and water resource management. using empirical model is one of the approaches of evaluating sediment yield. this research in kasilian watershed evaluates sediment yield by using geomorphology method and epm model with arc view gi...

Vegetation cover over time and space is the result of interactions betweenvegetation cover and environmental factors. Changes occurred in range covers are caused bymatrix dominance, one of the most important environmental factors. Decision support system(DSS) could be used for determining the rate and importance of each factor. Actually, inmethods based on DSS, relations between input and outpu...

The study uses 30 years of the third generation Advanced Very-High-Resolution Radiometer (AVHRR) NDVI3g monthly data from 1982 to 2012 identify natural clusters and important driving factors upstream watersheds in Taiwan through hierarchical cluster analysis (HCA) redundancy (RDA), respectively. Subsequently, as a result HCA, six were identified based on NDVI data, delineating unique characteri...
