This study, spawned from their original research that showed subsidence in southern Montgomery County was caused by exploitation of the Jasper aquifer, will investigate the combined effects of climate changes on coastal subsidence to enhance understanding of the deformation process. The Subsidence District has adopted regulations requiring reduction of groundwater withdrawals through conversion to alternate source water (e.g., surface water) in certain areas within the Subsidence Districts jurisdiction, including the land within Harris County MUD 501. regional water-level change maps. hbbd```b``NA$EHD]c@$wX2$'u1fHY b Neighbors.
