Scour Monitoring Programs

North Central Region Office monitors the cross sections of many fixed sites in the north and south Delta regions to help establish the natural variations in channel bathymetry under existing conditions. This information may also assist the evaluation of changes in the natural scour or sedimentation regime which might occur in these channels under the implementation of any future Delta plan. Sites in the south Delta near the Clifton Court intake gates have been monitored since 1969. Sites in the north Delta generally in the North Mokelumne and South Mokelumne rivers have been monitored since 1993. The number of locations monitored has increased over the years and currently 38 sites in the north Delta and 74 sites in the south Delta are monitored. Depending upon funding, the sites are visited once or twice a year � in the fall or in fall and spring.
