Hydraulic Model Study of Folsom Dam Joint Federal Project Auxiliary Spillway Confluence Area, Dates Covered July 2007 - February 2010

摘要

A 1:48-scale physical hydraulic model of the principal features of the Joint Federal Project at Folsom Dam was constructed and lasted at the Bureau of Reclamation's Hydraulics Laboratory. The model included the main dam spillways, the auxiliary spillway and stilling basin, the confluence area of the two exit channels, and a section of the downstream river channel. The primary objective of the physical modeling was to evaluate the three-dimensional flow characteristics in the vicinity of the confluence between the main dam exit channel and the auxiliary spillway channel in order to assess potential design and operational issues.
