Science activity

The USACE, with DWR sponsorship, has contracted for waterside erosion surveys of the Sacramento River system since 1998. As stated earlier, FPIIB began conducting waterside erosion surveys of the San Joaquin River portion of the State-Federal flood protection system Project levees in September of 2006. The primary purpose of these surveys is to: a) inspect the waterside levees for erosion activity, b) document and report new erosion sites, c) document and report the current condition of previously identified erosion sites, and d) rank and rate the severity of erosion sites based upon the findings from the field survey. The USACE and its contractors generate the report on erosion found in the Sacramento River system;FPIIB staff supplements their inspection reports with the USACE data as it becomes available.
