Bureau of Reclamation's Needs in Sediment Technology for the 21st Century. This paper provides a brief summary of Reclamation's sediment technology needs for the 21st Century.
More field testing is needed to improve their accuracy and applicabilities to field conditions.
Determination of the compatibility of measured results using different types of samplers is also important. Roughness varies with flow and sediment conditions. There is a lack of reliable and consistent methods for the determination of roughness coefficients under different flow and sediment conditions. FISP should evaluate and compare the relative accuracies and field applicability of such equipment.
