California Water and Environmental  Modeling Forum

Promoting Excellence and Consensus in Water and Environmental Modeling

  Technical Workshop
Flood Management Training
 (in cooperation with the California Department of Water Resources
and David Ford Consulting Engineers)

 October 7-9, 2015 from 9:00 to 4:30 pm
West Yost Associates Training Room
2020 Research Park Dr., Suite 100, Davis, CA 95618

Workshop Fee: $100 for CWEMF members, $200 for non-members, and $40 for students.
Refreshments included, lunch not included.

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 workshop is to describe those models, including their development, availability, and use. 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 CVFED riverine modeling (HEC-RAS) and floodplain modeling (FLO-2D), including demonstrations. Overview of the objectives of FloodSAFE modeling activities, procedures, and models used. (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 CVHS development, models used, and results. Discussion and demonstrations of unregulated flood flow frequency analysis, rainfall-runoff-routing, and transforming unregulated flood flow frequency curves to regulated flood flow frequency curves. Attendees will be introduced to DWR’s Library of Models and learn how to access FloodSAFE models and data sets. 
  • Day 3: Risk analysis and plan evaluation. Demonstrations of system-wide economic risk analysis, ecosystem benefits analysis, and change in risk attributable to levee and bypass modifications, reservoir re-operation, and enhanced flood warning. (NOTE: this will not be a tutorial on using HEC-FDA. Attendees should have at least a novice-level understanding of risk analysis concepts).

Important Notice Attendees are required to bring their own laptops with the following software pre-loaded: 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.
