Short summary
Two additional alternative mechanistic models are proposed that involve principles of load transfer considering the temporally and spatially redistributed stresses associated with groundwater extraction: i) Cosserat continuum mechanism, considering shear force in the aquifer due to hydraulic gradients in the aquifer; and ii) internal erosion of fine-grained (clay and silt) particles within the aquifer. Initial results based on simulations incorporating Cosserat mechanics look promising.
