395128 - California Hydrologic Vulnerability Assessment and Adaptive Planning Project

Wednesday, Jun 6
8:30 AM – 5:30 PM

The US Army Corps of Engineers (USACE) and California Department of Water Resources (CA DWR) are implementing a strategy for incorporating deep uncertainties, with an emphasis on hydrologic and climate uncertainties, into their decision-making processes. Of particular interest to USACE and CA DWR is better ability to anticipate and mitigate localized flood risk. This study will present progress made in the joint effort to date. The pilot study will analyze a watershed within the Sacramento River or San Joaquin Watersheds, utilizing a Hydrologic Engineering Center Watershed Assessment Tool (HEC-WAT) model of the pilot watershed, which was developed by the USACE from an existing Corps Water Management System (CWMS) model of the Sacramento River Watershed or San Joaquin River Watershed. Primary advances to be presented are: 1) adjustments made to observed data records to model hydrologic and climatic trends that are important to water resource infrastructure on a storm duration, monthly, seasonal, annual and inter-decadal time scales; and 2) the integration of software workflow to use weather generators, bootstrapping and other tools or techniques to capture current climatic and hydrologic variability. Finally, most-current recommendations for robust and flexible adaptation strategies developed to deal with the plausible losses of performance associated with the vulnerability assessment scenarios will be discussed.
