What is it about?

Natural recharge was computed from water balance model and daily water level fluctuations were measured to study the increase in water level due to artificial recharge. Numerical models were developed using Modflow to analyze the feasibility of different artificial recharge arrangements such as check dam, percolation pond with percolation wells individually, and in combination and evaluated the effectiveness of the structures in recharging the aquifer.

Why is it important?

Population growth and higher living standards have resulted in ever-increasing demand for water. Artificial recharge is found very effective for sustainable development of water resources and percolation pond was found to be the most appropriate structure for groundwater recharge for the study area.

Perspectives

This article important in the context of acute water scarcity in many parts of Asia as aquifer recharge is imperative in groundwater management plan in areas where over development has depleted the aquifer and deteriorated the quality of groundwater. Artificial recharge is becoming more prevalent in the recent years because it can be used to buffer against climatic variability and associated floods and droughts. To evaluate the long term effectiveness of individual and various combinations of artificial recharge arrangements, a field experimental setup was established and a comprehensive groundwater flow model was developed using MODFLOW.
