    Abstract

    Spatial patterns in suspended sediment transport and storage along the Sacramento River were assessed by evaluating the suspended sediment budget for the main channel accounting for all tributaries and diversions. Time series analysis was employed to quantify the relationship between streamflow and suspended sediment concentration for gauging stations along the main channel and signature tributaries. Sediment concentration records (of 2-yr duration) were extended using Box-Jenkins transfer function models to calculate annual rates of suspended sediment discharge over a 32-year period since dam construction on the Sacramento River. The suspended sediment budget was evaluated to identify reaches of net erosion or deposition. The results of the budget suggest the influence of tectonics and anthropogenic channel modification.
