Abstract

Abstract - The paper discusses an automated procedure for measuring turbidity and sampling suspended sediment. The basic equipment consists of a programmable data logger, an in situ turbidimeter, a pumping sampler, and a stage-measuring device. The data logger program employs turbidity to govern sample collection during each transport event. Mounting configurations and housings for the turbidimeters have been prototyped and tested or deployed at 16 gaging sites in northwestern California. Operational data are presented with examples illustrating storm load estimation.
