New generation water erosion prediction technology is being developed by the USDA Water Erosion Prediction Project (WEPP). The new technology is expected to replace the Universal Soil...
Scour Downstream of the Straight Drop Spillway
Tests made to determine the effect of high tailwater and long duration flows on scour downstream of the straight drop spillway stilling basin are presented in this paper. Results are presented...
Local Scour Downstream of a Tunnel Outlet Structure
The local scour downstream of two different types of outlet structures is studied in laboratory experiments with an alluvial sediment. The outlet structure terminates a hydraulic model...
A Model of Flow in Regulated Open Channel Networks
A model (NETWORK) is presented for the simulation of unsteady flow in regulated open channel networks. The operation of hydraulic structures, such as gates and weirs, are simulated as...
Channel Response to SCS Type-C Grade-Control Structures on Burney Branch, Mississippi
Five SCS Type-C grade-control structures were installed in Burney Branch in 1980 to remove 59.4 feet (18.1 m) of grade. The performance of the structures was evaluated in 1984 after they...
