Hi All, I finally got the official explanation given at http://www.india-wris.nrsc.gov.in/GWL/GWL.html? Here is what it says
Groundwater is an important source of drinking and agriculture in our country. But this is hard to be explored and analyzed being flowing in sub-surface. The level of water below ground is temporal and dynamic in nature. It is mainly controlled by rainfall pattern in relation to the aquifer material. Central Ground Water Board (CGWB) and State Ground water departments have implanted monitoring wells and measure ground water level regularly. The GW Level module provides the available water level data for 29 states & 7 UTs (excluding some hilly regions of north and north east India) for the period 1994 to 2016 as received from CGWB. It contains a layer having locations of more than 30,000 observation wells with 16 attributes (11 static and 5 temporal). Further, water level data is grouped according to four seasons viz. - Post-monsoon Rabi (January to March) - Pre monsoon (April to June) - Monsoon (July to September) - Post-monsoon Kharif (October to December) The user can view season wise water level of individual or multiple wells in graphical form as per predefined area as well as administrative/basin boundary. One can also assess the water level changes and compare its dynamic fluctuation in spatial and temporal domain through this sub info system.
