Landscape and Subsurface After Land Subsidence (MODFLOW-OWHM)

Post-subsidence diagram showing the relation between surface and subsurface processes with linkage to land subsidence. The linkages to subsidence deformation are briefly summarized for surface-water, landscape and groundwater flow processes. The potential changes in movement of water before and after the linked effects of subsidence result in redirected or reduced runoff, reduced streamflow and canal flows, reduced canal freeboard, additional connection of root zone to capillary fringe above water table, and reduced aquifer thickness and hydraulic properties (transmissivity and storativity).
