Abstract:

Groundwater is one of the most valuable natural resources, which supports human health, economic development and ecological diversity. The amount of water that will ultimately arrive at the water table is defined as natural ground water recharge. The amount of this recharge depends upon the rate and duration of rainfall, the subsequent conditions at the upper boundary, the antecedent soil moisture conditions, the water table depth and the soil type. The assessment of groundwater recharge from precipitation is a major part of hydrology and hydrogeology. The present study of groundwater recharge has been estimated at various locations in the Sirumugai study area which is located in the Coimbatore district, Tamil Nadu. The annual groundwater recharge, recharge coefficient have been estimated by using empirical methods and water table fluctuation method. The related rainfall data were collected from two rain gauge stations for the period of 1995 to 2014. The results showed that average groundwater recharge of six empirical methods and water table fluctuation method were varies with 5.51 to 101.20 mm per year and 67.5 to 340 mm per year respectively for the study area. Comparison of multiple methods is found to be valuable for determining the range of plausible recharge rates and for highlighting the uncertainty of the estimates.
