Federal Interagency Sedimentation Project (FISP)
* How can the efficiency and accuracy of sediment sampling and analysis equipment and techniques be improved to provide more cost-effective and continuous data for Reclamation managers to use in project management decisions?
Need and Benefit
Sediment transport and water quality data from streams entering and leaving our facilities are essential to perform many of the analyses needed to effectively operate, maintain, and sustain our facilities. Every year, Reclamation funds data collection efforts in streams and at existing gauging stations to obtain sediment data for a variety of analyses. Sediment data are used throughout Reclamation to:
* Quantify and predict sediment volumes flowing into and out of our reservoirs and diversion facilities
* Estimate bridge scour and channel degradation
* Monitor construction impacts
* Design sediment detention structures, channel and habitat restoration features, and channel bank and bed stabilization works.
This research will produce increasingly more accurate and economical equipment and methodologies to ultimately increase the amount of sediment data available and potentially reduce the cost of data collection and management solutions. Many studies are now being conducted with little or no actual sediment data because data are unavailable or too costly to obtain. Often for safety reasons, samples are not collected during peak flow events; on average, especially in the Western United States, it is these peak flow events that transport the majority of the sediment load. The development of new technologies that can automatically and continuously collect accurate sediment data is a goal of the project that would benefit resource managers in all Federal agencies. The availability of accurate sediment and water quality data is essential for the effective and defensible analysis of sediment transport and its impacts on our project features.
