Managed aquifer recharge for seawater intrusion

Abstract

Ground water is, as a rule, continuously seen as a dependable wellspring of supply to satisfy the requirements of residential water system and mechanical sections of the country. The progression practices during the years have ominously impacted the ground water dominion in various areas of the country. Seawater intervention or the movement of brine into the fresh formation zone will increment groundwater saltiness, posing an enormous ecological effect in coastal regions universally. Ocean level ascent and decrease in groundwater levels due to over usage may end up in saline water intervention; moving major ions and nutrients in groundwater. “Saltwater invasion is the biggest and much debated water story in the world these days. It’s a silent problem. It’s easy to ignore politically however it will ruin the water supply for future generations.” India’s water security is in a very unpredictable position. Even by conventional estimates, 40% of individuals in India won’t have drinking water by 2030. As indicated by an IBRD report, at least 21 Indian urban communities are heading towards zero groundwater level by 2020. Managed formation Recharge (MAR) could be an encouraging modification to the present lifestyle to cut back exposure to temperature change and hydrological variability. MAR can take a significant position as a measure to curb over-abstraction and to restore the groundwater balance. It can be utilized to recharge aquifers subject to decreasing yields, to control saltwater intervention or to prevent land collapse. MAR may likewise be employed to support or improve the working of ecosystems and the nature of groundwater.
