MAR Technique to Reverse the Declining Trend of Groundwater Level in Barind Area, NW, Bangladesh

Abstract

The study was carried out in the drought prone water stressed Barind area to know the state of rainfall, trend of groundwater level and groundwater management options including Managed Aquifer Recharge (MAR) techniques. Rainfall and groundwater level data have been used and shown a decreasing trend in Godagari and Mohonpur Upazila. But in Niamatpur Upazila rainfall is in reverse condition of rising trend. Decreasing trend of groundwater level (GWL) has been found in the entire study area. The decreasing trend of GWL demands judicious management of groundwater for the area. For recovery of GWL as well as groundwater management, a recharge well as MAR structure has been installed and observed that the situation is better than the before and increasing GWL. More research and study are necessary to know about the trend of groundwater level for the whole Barind area and to introduce proper designed and modified MAR techniques to reverse the declining situation of GWL.
