Model calibration is one of the most important steps on groundwater evaluation trough numerical models. We have to give appropiate model parameters that represent in some sense the observed conditions of the groundwater flow regimen usually available as piezometric heads.
If we put any parameter just to fit the observed data we would end up with a model with low confidence, if we stick to the parameters taken in the field we won´t match the observed values. Somewhere in the middle is the right approach for model calibration. We have developed this webinar with an applied case of groundwater calibration of a local model with 3 piezometric heads, 3 layers and 4 boundary conditions.
The webinar cover the following topics:
Review of the base groundwater flow model.
Analysis of the water balance.
Observation data output files.
Scripts for model prediction metrics. Generation of observed - calculated plots.
Developing a "what would happen if.." approach.
Strategy of "trial and error" for model calibration.
Evaluation of previous model sensivity analysis.
Final model calibration.

Trainer
Saul Montoya M.Sc.
Saul Montoya M.Sc. is a Hydrogeologist and Numerical Modeler. Mr. Montoya is a Civil Engineer graduated from the Catholic University in Lima with postgraduate studies in Management and Engineering of Water Resources (WAREM Program) from Stuttgart University – Germany with mention in Groundwater Engineering and Hydroinformatics. Mr Montoya has a strong analytical capacity for the interpretation, conceptualization and modeling of the surface and underground water cycle and their interaction.
He is in charge of numerical modeling for contaminant transport and remediation systems of contaminated sites. Inside his hydrological and hydrogeological investigations Mr. Montoya has developed a holistic comprehension of the water cycle, understanding and quantifying the main hydrological dynamic process of precipitation, runoff, evaporation and recharge to the groundwater system.
