Description

The webinar will focus on the physical modeling used to assist the design of the new spillway and its energy-dissipation basin. The modeling used a 1:24 length-scale hydraulic model supported by a FLOW-3D numerical model, used mainly to check uniformity of flow at the spillway’s entrance. The effects of the spillway steepness and the spillway chute’s convergence (about 20% from top to base), and various site constraints, created a new form of energy-dissipation basin: a compact basin and fitted with a single row of baffle blocks that blended aspects of a slotted roller bucket and a baffled stilling basin. Pressures were measured in the basin to assist estimation of loads and related to flow through the basin. https://training.ussdams.org/p/25grossdamwebinar
