Mathematical aspect of ground water flow related to unconfined aquifer and a change in saturated thickness with variation in piezometric level so, permeability
In this mathematical expression, inducing ground water mounding through artificial recharge using rainwater stored in specially designed basin. This technique can be implemented to an unconfined stratified aquifer with horizontal impervious base receiving vertical recharge. Authors have established various correlations for suitable recharge scheme.
Added would be the tremendous pressure to meet water requirements for other purposes such as for industrial use, environment and ecological management etc. emanating from population growth, the land use policies, degradation of water resources and depletion of aquifers in the country. Need for water conservation is deeply felt worldwide. Rooftop rainwater harvesting system is looked upon as one of the most feasible and economical ways of water conservation. With increasing problem of water scarcity, planning and designing rooftop rainwater harvesting is gaining wider importance to meet ever-increasing water demand and ground water depletion.
Facts and figures say that 1 mm rain that falls on 1 sq.m. Area amount to 1 liter of water. Therefore, we can very well guess the quantity of rainwater available in our area. Therefore, we should adhere to the practice of collecting and holding the rainwater that falls in our residential premises. We should learn the art of holding, deflecting and percolating the rainwater.
A long-term perspective planning of water resources is required to meet various competing demands on sustainable basis. Artificial Recharging of Ground water into soil aquifer is a Viable- Economical solution. An author have set up case studies for recharge scheme at site and gives satisfactory results, few are listed.
