Abstract

The California Department of Water Resources (DWR) and the U.S. Bureau of Reclamation Mid-Pacific Region (Reclamation) have developed CalLite as an interactive screening model for evaluating various Central Valley water management alternatives. The CalLite model has been used as a negotiations tool in a variety of stakeholder processes for improved understanding of water system operations and for consensus based decision-making. The model has been applied to studies related to: the Bay Delta Conservation Plan, delta regulations, system reoperation, and other planning processes. CalLite was developed using the Water Resources Integrated Modeling System (WRIMS) software that uses a linear programming solver to simulate the system. The syntax of the model algorithms is written in Water Resources Simulation Language (WRESL). A Java-based graphical user interface (GUI) for CalLite was developed to facilitate ease of use by stakeholders. The GUI allows simplified modification of a variety of water management actions, including: alternative conveyance options, demand management, and Delta channel flow and salinity targets. CalLite maintains the hydrologic, operational, and institution integrity as represented in the companion model CalSim, DWR and Reclamation's more detailed water resources simulation model. The results obtained from a typical CalLite run (time) are within 1% of a corresponding CalSim run (30 minute run time). The short run time and straightforward interface encourages managers, policy makers, and others without extensive modeling backgrounds to use CalLite as a tool for exploring potential water resource management decisions in California.
