Drop Structures for Walnut Creek Project, Walnut Creek, California. Hydraulic Model Investigation.
Abstract
Walnut Creek project will provide for enlargement and rectification of the existing channels of Walnut, Lower San Ramon, and Las Trampas Creeks. Three grade control structures and one energy dissipating structure will be used to reduce velocities and dissipate excessive energy from flood flows. Model investigations were conducted on 1:20-scale models of drop structures 2 and 3. Tests were concerned with determining the optimum size and configuration of the stilling basins for these structures, the stability of the riprap downstream from the stilling basins, and the adequacy of the inlet transition upstream from drop structure 2.
