Documentation of a computer program to simulate aquifer-system compaction using the modular finite-difference ground-water flow model
S. A. Leake, David E. Prudic
1991, Techniques of Water-Resources Investigations 06-A2
Removal of ground water by pumping from aquifers may result in compaction of compressible fine-grained beds that are within or adjacent to the aquifers. Compaction of the sediments and resulting land subsidence may be permanent if the head declines result in vertical stresses beyond the previous maximum stress. The process...
