The Natural Resources Conservation Service (NRCS) has updated its DAMS2 Structure Site Analysis computer program to reflect the evolving technology related to earth (soil and rock) spillway design and analysis. The changes include: 1) incorporation of vegetal retardance (discharge dependent flow resistance) into a water surface profile routine for use in computing the head discharge rating for the spillway, 2) computation of erosionally effective boundary stress for stability design of the exit channel, and 3) evaluation of breach potential using a three-phase erosion model. NRCS has tested the new software and is currently utilizing it for spillway design and analysis. The new software was renamed SITES and version 95.3 will be distributed in February 1996. This article provides an overview of the program changes and their significance to the user. |
