Deltares

iPEST is a software package that performs automated parameter estimation of groundwater models. It works by minimizing the summed differences between measured and calculated values, such as groundwater levels and flows, by adjusting model parameters such as hydraulic conductivities and storage coefficients. It uses the Levenberg-Marquardt method to minimize the objective function through successive iterations, using gradient-based and Gauss-Newton approaches to guide the parameter adjustments toward the minimum summed difference. The document provides details on iPEST's parameter estimation methodology and capabilities.

  • 2. iPEST Minimaliseer gesommeerde afwijkingen : - Grondwaterstanden met metingen; - Berekende afvoeren met afvoermetingen; - etc. door aanpassen model parameters: - doorlatendheden en weerstanden; - bergingscoefficienten; - etc. 17 juni 2014 Minimale gesommeerde afwijking Groter gesommeerde afwijkingen
  • 3. iPEST Minimalisatie strategie - richting - Gebaseerd op Levenberg – Marquardt – kleinste kwadraten methode - Gradienten (ver weg van het minimum) en Gauss-Newton approximation (dicht bij het minimum) 17 juni 2014 Gradienten Methode Gauss-Newton Methode
  • 4. iPEST Minimalisatie strategie - stapgrootte - Grootte stap bij kleine verbetering doelfunctie (kleine gevoeligheid); - Kleine stap bij grote verbetering doelfunctie (grote gevoeligheid); - Maximale verandering per parameter per richtingsverandering; 17 juni 2014 Ongevoelige parameters vertragen process (scaling, eigenvalues)
