Document Description
The U.S. Army Corps of Engineers will collect suspended sediment samples and riverbed samples in the American River to inform design of future erosion protection projects and mitigation projects as part of the American River Watershed Common Features (ARCF) 2016 Project. A motor boat would be used to collect samples with a suspended sediment sampler that collects a continuous sample throughout the water column. Bed material samples would be collected at the same locations as the suspended sediment samples. Bed materials would be sampled using a boat mounted sampler that is lowered on a cable to the bottom of the river where a spring-loaded release is activated causing a bucket to collect the sample. The sampler would penetrate approximately 2 inches into the river bed and collect approximately 18 cubic inches of material for each sample.
