Short summary
The authors have developed Percolation Theory-based methodologies to estimate alluvium modulus as a function of lithology, depth, groundwater level and effective stress. Applied at aquifer stress points, such as major pumping wells, this facilitates subsidence modeling at its’ sources. Modeled subsidence is then propagated over time across the basin from the source(s) using a time delay exponential decay function similar to the soil mechanics consolidation coefficient, only applied laterally.
