Water logging and flooding is a common problem that most of our society face now a days. Here is a successful cast study shows effective Rainwater recharge system that solves water logging and flooding problem and in addition stores rainwater in shallow aquifer zone to raise ground water. Solving two critical problems 1. water logging 2. depleting ground water with one Rainwater harvesting and recharge system.
Rainwater harvesting can avert the climate change scenerio : Because increased temperature causes greater evapotranspiration, higher agricultural water use, and lower runoff, while increased precipitation causes lower water consumption in agriculture and higher runoff, these changes have the opposite impact on water vulnerability(Alcamo et al., 1997). We calculate that the annual precipitation effect is more significant than the temperature effect from a global viewpoint, and that total annual runoff rises and water scarcity is somewhat less severe under climate change. A 10-percentile dry year's mean worldwide runoff rises from 178 mm/yr in 1995 to 191 mm/yr in 2025 and 211 mm/yr in 2075. These findings can be summed up in terms of the quantity of individuals encountered with water scarcities in the future. The depth of the water table and the quality of the groundwater vary from location to place. It varies with the seasons and is mostly controlled by the quantity and make-up of dissolved solids that are present in it.
