Foreword

This is the nineteenth annual progress report of the California Department of Water Resources' San Francisco Bay-Delta Evaluation Program (Work Authority 1463), which is carried out by the Delta Modeling Section. It documents progress in the development and enhancement of the Delta Modeling Section's computer models and reports the latest findings of studies conducted as part of the program.

For the last five years, the Section has been developing the new Delta Simulation Model (DSM2). The model was recently made public through the Section's World Wide Web home page: http://wwwdelmod.water.ca.gov. This report contains a description of the theory behind the model and information on how to run the model and its support programs
