DWR’s flood system improvement efforts continue to reduce flood risk in California. To support decision making for these efforts, DWR has developed models of flood hazard, flood consequence, flood management system operation, and economic and life risk within the Central Valley. The objective of this three-day workshop is to describe those models, including their development, availability, and use with focus on the Central Valley Flood Protection Plan (CVFPP). Application of the models for floodplain mapping, economic risk analysis, and flood management planning will be demonstrated. To the extent feasible, attendees will use the models, datasets, and published results of application for illustration.

• Day 1: Hydraulics-focused with emphasis on Central Valley Floodplain Evaluation and Delineation (CVFED) Program riverine modeling (HEC-RAS) and floodplain modeling (FLO-2D), including demonstrations. Overview of the objectives of DWR’s modeling activities, procedures, and models used. Attendees will be introduced to DWR’s Library of Models and learn how to access flood management models and data sets. (NOTE: This will not be a tutorial on using HEC-RAS or FLO-2D. Attendees should be familiar with both.)
• Day 2: Hydrology-focused with emphasis on Central Valley Hydrology Study (CVHS) development, models used, and results. Discussion and demonstrations of unregulated flood flow frequency analysis, rainfall-runoff routing, transforming unregulated flood flow frequency curves to regulated flood flow frequency curves, and developing climate change scenarios. (NOTE: This will not be a tutorial on using HEC-DSSVue, HEC-HMS, or HEC-ResSim. Attendees should be familiar with all three.)
• Day 3: Risk analysis and plan evaluation and current modeling activities. Demonstrations of system-wide risk analysis and change in risk attributable to alternatives. (NOTE: This will not be a tutorial on using HEC-FDA. Attendees should have at least a novice-level understanding of risk analysis concepts.) Other modeling activities will be presented including Delta frequency analysis, HEC-RAS 2D and bypass modeling, and the Lower Elkhorn risk assessment.

Important Notice – Attendees are required to bring their own laptops with the following software pre-loaded: HEC-HMS, HEC-RAS, HEC-ResSim, HEC-FDA, HEC-DSSVue, FLO-2D, and IPAST. Prior to the workshop, links to the free/public versions of the software will be provided.
