What are the Giophysics Survey needed before digging a well
hello everyone, I'm living In North Sudan and we are having dug wells in our area. We had constructed them 4 years back. Now all the wells are dried and there is no water. We are planning to dig new wells as these old wells were not constructed properly so there is no point in reutilising these wells. We don't want to repeat the failure in getting no water this time. Please suggest what are the geophysics analysis that should be done before digging wells? Also while constructing wells can we make provisions for well recharge?
