Abstract
AbstractA chute spillway, also called a trough spillway, is designed to dispose of surplus water from upstream to downstream through a steeply sloped open channel. The chapter describes the functions of the various components of a chute spillway and presents the hydrologic, hydraulic, and structural designs of chute spillways. The hydraulic design of the entrance or approach channel, inlet or control structure, chute channel or discharge carrier and outlet or energy dissipater is presented. The structural stability is analysed considering the weight of the structure and the uplift pressure created due to the differential head between the upstream and downstream. A detailed procedure to analyse the stability of the structure against overturning, tension, and compression is demonstrated through a solved example.
