Entropy-Based Approach for Assessing Natural Recharge in Unconfined Aquifers from Southern India Academic Article uri icon


  • An entropy-based approach is developed for assessing natural groundwater recharge in unconfined aquifers from Southern India. The wells are located in weathered zones which exhibit spatial variability in natural recharge. To determine the fractional amount of rainfall (called natural recharge) marginal entropies and transinformation of rainfall and depth to the water table at selected wells are calculated. Then a ratio of transinformation to marginal entropy of rainfall is used as a measure for assessing natural recharge. Calculated natural recharge yields a good agreement with the results of recharge zones obtained using Remote Sensing (RS) and Geographical Information System (GIS) techniques. © 2012 Springer Science+Business Media B.V.
