Developing a Water Supply Planning Model for East Bay Municipal Utility District
  Gary Palhegyi, P.E., D.WRE & Ben Bray, Ph.D., P.E.—East Bay Municipal Utility District

For decades, EBMUD has relied on a FORTRAN computer model of its raw water supply system for evaluating system reliability and performance under varying configurations and supply scenarios. In 2012, EBMUD began the process of identifying and evaluating potential software alternatives; upon which RiverWare was ultimately selected to replace the older FORTRAN model. Although a number of reasons can be sited for making this change, a primary reason is to bring EBMUD up-to-date in terms of modern software capabilities; increasing flexibility in testing changes in operating policy, improving system resolution, improving time step resolution, and enhancing input/output processing.

The Mokelumne River water supply planning model simulates operations over 92 years of historic hydrology. Although the model is currently designed for long-term planning, one goal is to modify the model for day-to-day operations and short-term forecasting. One of the more challenging elements for EBMUD was the need to forecast in April the future storage conditions in September. Each year, the April forecast is required for setting rationing goals, triggering supplemental supply options, cold water pool support and for defining environmental flows.

In this presentation, EBMUD will summarize model development, calibration and testing, and illustrate results with examples.
