Floodplain development in an engineered setting.

- Abstract
The article presents a study which examines the floodplain in engineered flood bypasses. It investigates the effects of floods in Sacramento River, California basin through the analysis of hydrographic characteristics, estimation of event-based sediment discharges and reach erosion and deposition. It discovers that sediment routing for large, iconic flood indicates high rates of sedimentation in major bypasses, and a consistent spatial pattern of high sediment accumulation in upstream and downstream of lateral flow diversions. Meanwhile, flood deposits accord with the spatial pattern wherein it suggests that a quasi-natural physical process of levee construction by advective overbank transport and deposition of sediment is operating.
