A multitude of biophysical factors affect the dynamics of the nature of water balance of a landscape. Understanding the spatio-temporal characteristics of these factors is critical in understanding the Rain Water Harvesting potential. These factors include various families of biophysical factors that can be grouped into [1] Hydroclimatic , [2] Edaphic/soil related, [3] geomorphological , [4] Vegetation related, and [5] Geological. This page helps the uers understand and visualize these variables in user defined countries.
