Enhanced Artificial Neural Network with Harris Hawks Optimization for Predicting Scour Depth Downstream of Ski-Jump Spillway

Applied Sciences, 2020
A spillway is a structure used to regulate the discharge flowing from hydraulic structures such as a dam. It also helps to dissipate the excess energy of water through the still basins. Therefore, it has a significant effect on the safety of the dam. One

Estimation of Scour Depth at Bridge Piers by Using FASTER Model and Experimental Formulas [PDF]

مهندسی منابع آب, 2017
Bridges are one of the most important river structures. One of the main causes of bridge failure is local scour at bridge piers. Yearly, Many bridges failed around the world because of disregarding hydraulic factors.

Influence of scour depth and type on p–y curves for monopiles in sand under monotonic lateral loading in a geotechnical centrifuge

Ocean Engineering, 2020
The influence of scour on the lateral response of monopile foundations for offshore wind turbines is investigated in this paper. Application of lateral load-displacement (p-y) curves to predict the lateral pile behaviour is subject to uncertainty as many
