Automatic calibration of pumping test data with MODFLOW 6, Model Muse and Pest

This webinar walks hydrogeologists through the full workflow of automatic calibration of pumping test data using MODFLOW 6, ModelMuse, and PEST. A real pumping test scenario — comprising a 6-hour pumping phase and an 18-hour recovery phase — is set up in ModelMuse, where the well is conceptualized as a Multinode Aquifer Well (MAW) boundary condition to accurately represent multilayer aquifer interactions. PEST is then implemented to automatically estimate key hydraulic parameters including hydraulic conductivity, specific storage, and specific yield, eliminating tedious manual calibration and delivering reproducible, optimized results. Whether you're new to parameter estimation or looking to streamline your existing workflow, this session offers a practical, hands-on guide to modern groundwater model calibration.

Instructor / Instructor:

Saul Montoya M.Sc

Hydrogeologist - 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 an holistic comprehension of the water cycle, understanding and quantifying the main hydrological dynamic process of precipitation, runoff, evaporation and recharge to the groundwater system.
