Normally groundwater recharge is estimated using methods based on water balance, water table fluctuations, fixed factor of annual rainfall and tracer movement. In many of these methods water stored in the vadose zone and evapotranspiration are not accounted properly. These factors control groundwater recharge to a large extent, particularly in arid and semi-arid regions which are normally characterized by a deep water table, thick vadose zone and high evapotranspiration.

To carry out present study, ecotourism auditing survey has been used as a potential tool in ecotourism with special reference to assess visitor's management in Soor Sarovar Bird Sanctuary, Agra.
