Runoff

Groundwater is a natural replenishable resource. It is an important source for various purposes, including drinking, irrigation and industrial, due to insufficient surface water supply and frequent failure of monsoon. Identification of groundwater zones depends upon many factors such as distribution of rainfall, runoff, grain size of soil, topographic features, type of landform, drainage conditions, lithological characteristics, land use practices, depth to groundwater level and environmental constraints, which are not uniform in any area.
