Book excerpt: Sediment deposition occurs in the lower reaches of the concrete-lined Corte Madera Creek flood control channel because the elevation of the channel bottom is below sea level. These sediment deposits, combined with the presence of tube worms and barnacles on the channel walls, reduce the flood-carrying capacity of the channel. The upstream portion of the original flood control project was not completed and flood flows above 3,000 cfs are not contained in the natural channel upstream. Thus, there is reduced flow competency to carry the coarse sediment load delivered by flood flows. With annual maintenance and upstream containment of breakout flows, most of the sediment deposited in the concrete channel from seasonal antecedent flow can be washed out by the time the flood peak occurs. An HEC-6 numerical sedimentation model study was conducted to evaluate several alternative plans to provide flood containment and sediment storage while also maintaining the natural characteristics of the upstream channel.

Available in PDF, EPUB and Kindle. Book excerpt: A one-dimensional numerical model was used to determine the effects of sediment deposition in the Corte Madera Creek flood control channel. The effect of accumulated gravel deposits in the concrete-lined channel on hydraulic roughness was evaluated. The effect of a proposed sediment trap at the upstream end of the project on reducing gravel deposits was determined. The performance of the project during a design flood event was simulated. (fr).

Book excerpt: A concrete-lined supercritical-flow flood-control channel was designed for Mission Creek in Santa Barbara, California. The design did not include a debris basin at the upstream end of the channel, so there was potential for a significant quantity of bed load to be delivered during a flood event. An existing concrete-lined flood control channel on Corte Madera Creek in Marin County, California lacks a debris basin at its upstream terminus and carries significant bed load through a supercritical flow reach. This study was conducted to determine the influence of potential bed load transport on hydraulic roughness in the concrete-lined channel. For Mission Creek, a numerical sedimentation model study was conducted to determine the quantity and size of bed load transport that would occur during a flood event. flume studies, which simulated flood unit discharges in Mission Creek and Corte Madera Creek were conducted to determine hydraulic roughness due to bed load transport. An equation was developed that accounted for the additional hydraulic roughness due to bed load transport in concrete channels. The equation is applicable for gravel concentrations up to about 3,000 mg/l, which is the concentration where sediment began to accumulate on the bed.

Book excerpt: Sediment dynamics in fluvial systems is of great ecological, economic and human-health-related significance worldwide. Appropriate management strategies are therefore needed to limit maintenance costs as well as minimize potential hazards to the aquatic and adjacent environments. Human intervention, ranging from nutrient/pollutant release to physical modifications, has a large impact on sediment quantity and quality and thus on river morphology as well as on ecological functioning. Truly understanding sediment dynamics requires as a consequence a multidisciplinary approach.River Sedimentation contains the peer-reviewed scientific contributions presented at the 13th International Symposium on River Sedimentation (ISRS 2016, Stuttgart, Germany, 19-22 September 2016), and includes recent accomplishments in theoretical developments, numerical modelling, experimental laboratory work, field investigations and monitoring as well as management methodologies.

Available in PDF, EPUB and Kindle. Book excerpt: Despite the mechanisms of reservoir sedimentation being well known for a long time, sustainable and preventive measures are rarely taken into consideration in the design of new reservoirs. To avoid operational problems of powerhouses, sedimentation is often treated for existing reservoirs with measures which are efficient only for a limited time.Th
