| Abstract: | Geographical design of riparian buffers with long-term vegetation cover for environmental restoration in agricultural watersheds needs to assess how much farmland is located in the buffers of a concerned watershed.Traditionally,this assessment was done by field surveying and manual mapping,which was a time-consuming and costly process for a large region.In this paper,remote sensing(RS) and geographical information system(GIS) as cost-effective techniques were used to develop a catchments-based approach for ... |
