Sea level rise and artificial groundwater recharge. A study on the feasibility of geohydrologic management

Abstract

Intercepting 1% of the global rainfall of a one year period and storing it by artificial recharge in the subsurface of semi-arid areas could lead to a drop in sea level of less than 15 mm. Artificial recharge for this purpose is not the solution to the problem of sea level rise. Artificial recharge of 1% of the global annual rainfall means the equivalent of 110 times the artificial recharge in the State of California, USA. A calculation is presented on the dimensions of a pilot project on the same scale as the artificial recharge in California. This pilot project is situated SW of Lake Chad in Nigeria. Artificial recharge, though perhaps not on that scale, is certainly feasible if intended to provide water for development. -from Author
