Hydrogeological Characterization By Specific Yield Determination In Parts Ofaraniyar- Kortalaiyar (A.K) Basin, Thiruvallur District, Tamilnadu, India
Authors(3) :-Kumaresan K, Vinodh K, Gowtham B The study area, part of Kortalaiyar and Araniyar river basin ,Tamil Nadu is covered by alluvium of both rivers and has good groundwater potential. Hence, Chennai metropolitan water supply and sewerage Board supplied groundwater to cater habitants of sub-urban areas of Chennai for more than 3 decades in this region. Due to heavy pumping, groundwater levels have declined and sea water has been intruded around in the study region particularly in Minjur area. The hydrological characterization of specific yield parameter was determined for the unconfined alluvial aquifer in the four well fields constructed in the study area. Conducted Step Drawdown Test (SDT) for 4 steps of 60 minutes duration and on the basis of the results, Long duration Aquifer Performance Test(APT)(pumping test) was conducted for 5800 to 10000 minutes well fields and Specific yield was computed by three methods: Volume Dewatering Method, Ramsohoye – Lang Method and Curve Matching Method (Neuman). Specific yield (Sy )of sand aquifer is found to ranging7% at ponneri and upto 20% Minjur.
