Little Dell Outlet Structure, Utah; Hydraulic Model Investigation.

Abstract

A 1:10-scale physical model of the discharge outlet, plunge pool, and exit channel was used to investigate and develop a practical design that would provide satisfactory hydraulic performance. Operation of the model with the original design indicated satisfactory performance in the conduits and jet flow gates. However, failure of the riprap in the plunge pool and exit channel was observed. The side slopes of the plunge pool and exit channel were modified to provide a stable environment of the riprap. Keywords: Spillway; Dams; Energy dissipation; Flood control; Jet flow gates; Plunge pool; Riprap. (kt)
