Monitoring of a watershed environment using remote sensing and GIS

Deforestation and land development for agriculture and urbanisation are affecting the watershed environment especially its water resources. Remote sensing data and GIS can be used to estimate some parameters and simulate the effects of vegetation and climate on water yield of a vegetated watershed....
