Purpose and Objectives

The California Water and Environmental Modeling Forum (CWEMF) in collaboration with the U.S. Bureau of Reclamation commissioned this peer review to provide an independent analysis and constructive suggestions about the strengths and weaknesses of three integrated groundwater/surface water models commonly used in the Central Valley of California: IWFM (Integrated Water and Flow Model), HGS (HydroGeoSphere) and MODFLOW.  The peer review panel consists of two external reviewers who were selected for their expertise in the development and application of integrated groundwater/surface water modeling. The panel consists of Dr. Hubert Morel-Seytoux of Hydroprose Consulting International and formerly of Colorado State University, and Dr. Thomas Harter of U.C. Davis. 

The purpose of the peer review is to evaluate the capabilities of these models for performing the various types of analyses that integrated groundwater/surface water models are typically employed in California’s Central Valley.  The peer review panelists will highlight areas of the draft report at this workshop.  The remainder of the time will be used for public discussion, comments, or questions for the review panelists. 

You may submit written comments on the report before May 10th 2013 to:
