Groundwater is a renewable natural resource and dynamic groundwater resource is the part which is recharged annually and exploited largely. The study area is situated on the southern bank of River Brahmaputra. The main source of groundwater recharge in the area is precipitation. The study is an attempt to evaluate the groundwater dynamic resource potential by quantifying the gross annual natural groundwater recharge and to find out the stage of development of groundwater in the area for a better planning and development. Water table fluctuation method, rainfall infiltration factor method and empirical methods have been applied for the quantitative evaluation of the dynamic groundwater resource potential in the area. A point recharge zone map was prepared in GIS by the interpolation of thirteen years data on average fluctuation values. The result obtained by point recharge zone method using groundwaterlevel fluctuation & specific yield data gives a more realistic assessment of groundwater recharge, which is found to be 484 MCM. The stage of groundwater development is found to be less than 70% and no longterm decline in groundwater levels has been observed. The study area comes under the safe area category and the groundwater potentiality in the area is found to be very good. [ABSTRACT FROM AUTHOR]
