Watershed and Urban Hydrology Modeling Workshop California Water

Watershed and Urban Hydrology Modeling Workshop California Water and Environmental Modeling Forum Secretary of State Building Auditorium, Sacramento June 22, 2007

Workshop Purpose Introduce participants to: • watershed and urban hydrology models, • the capabilities and data requirements of each model, and • how the models are used for specific applications.

Watershed/Urban Hydrology Models • Quantify runoff flow rates and WQ impacts • Calculate TMDL load allocations; • Size storm water control facilities, delineating flood plain areas, reservoir spillway design; • Evaluate storage, treatment, and other best management practices for NP source load reductions; and • Compare trade-offs of sewer extensions vs. on-site wastewater systems.

CWEMF • Mission: to increase the usefulness of models for analyzing California’s waterrelated problems • Provide a consensus-building atmosphere on water-related issues

CWEMF Services • Facilitate open, constructive discussion of conflicting opinions on physical, chemical, biological, and economic modeling • Conduct problem-solving workshops to address technical disagreements • Organize technical training and educational workshops

CWEMF Services, cont. • Coordinate model development, refinement, and use through interagency model user groups • Conduct impartial peer reviews of water and environmental models
