Fully hydro-mechanical coupled Plug-in (SUB+) in FEFLOW for analysis of land subsidence due to groundwater extraction

Fully hydro-mechanical coupled Plug-in (SUB+) in FEFLOW for analysis of land subsidence due to groundwater extraction

Extensive groundwater extraction leads to the drawdown of the groundwater table, which can increase the stress of soils and lead to land subsidence. Analyses of land subsidence generally require numerical models based on the poroelasticity theory. FEFLOW is a well-known commercial finite element sof...
