Characterization of an Aquifer through Inverse Modeling from Pump Tests

This model uses the Optimization interface to solve the inverse problem for determining the spatially variable hydraulic conductivity on a discretized quadratic grid from a number of aquifer pump tests.

Because the number of observations is smaller than the number of unknown parameters, a geostatistical penalty term is used to discriminate between solutions with comparable fitness values.

The measurement data is generated from a given forward model implemented using the Darcy's Law application mode, making it possible to analyze the efficiency and accuracy of the inverse method as well as the optimization solver's performance.

Hydraulic conductivity obtained by inverse modeling using 24 observations.
