What effect does concretization (paving/flooring with concrete) has on ground water table
I found this on the USGS website. It states the effect of increased pavement coverage due to urbanization is to reduce the recharge rate of ground water, because the water is diverted elsewhere.

Also, with urbanization comes the use of storm water drains. The rain water that would have soaked into the ground and recharged the ground water is diverted to streams via the storm water systems (pipes and channels) which can result in flooding elsewhere.
