The removal of water from aquifers, such as fine grained sediments. The rock compacts because water is partly responsible for holding the ground up, and when the water is removed, the rock falls on itself.An excessive extraction of groundwater is the primary reason for land subsidence. This is particularly a problem in the southwestern United States.

subsidence
How do you calculate subsidence rates?
survey the land or entire area with surveying equipment, look at previously recorded survey data from over the years, compare your findings with those previously taken, to see what the rate of subsidence is for the area.
How does removal of groundwater cause land subsidence?
Water in the ground occupies the volume between the individual grains of material in the rock or soil from which the ground is composed. Thus wet clay, for example, will shrink in volume as it drys out and cracks may appear too. A similar thing will occur if groundwater is removed and the land dries out - it will shrink (subsidence) and cracks may also appear.
