Modeling Land Subsidence Processes
Detailed Description
Diagram showing the relation between surface and subsurface processes before and after 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).

Using Numerical Models to Simulate Subsidence
The California Water Science Center has been involved in multiple studies simulating land subsidence associated with groundwater withdrawal. The simulations can be used to estimate the magnitude, location, and timing of subsidence. They can also be used to evaluate management strategies to mitigate adverse effects from subsidence while also optimizing water availability.
