Large wood increases the morphological and hydraulic complexity of rivers, yet it may block modify flood discharge capacity structures. To assess related risk, blockage probability estimation for structures such as reservoir spillways is needed. This work presents unstudied parameters large with a reservoir-type approach flow, where inflow velocity has negligible magnitude. Experiments were con...

The Ogee Spillway is one of the most crucial flood control structures, and it developed at same time as dams. Spillway's downstream portions experience scouring due to flow, a problem that persists in reality. This paper aims investigate hydraulic performance stepped block dissipater using three-dimensional simulation model. dissipated was given new distribution may be one, two, or three rows t...

Abstract Cavitation is among the most complex and common damage occurring in spillway structures, which one of expensive parts a dam. The cavitation index, as efficient approaches, can be used to analyze this important hydraulic phenomenon. present study examines changes index caused by convergence angle an ogee spillway's sidewalls with arc plan. To end, was constructed on 1:50 scale. Then, it...

Over the past decades, significant advances have been achieved in hydraulic structures for dams, namely water release such as spillway weirs, chutes, and energy dissipators. This editorial presents a brief overview of eleven papers this Special Issue, Advances Spillway Hydraulics: From Theory to Practice, frames them current research trends. Issue explores following topics: inlet structures, tr...
