Spillways are essential parts of dams, in which the main task of these structures is to allow
the passing of excess water and floods from the upstream to the downstream. In this regards …

The discharge coefficient (Cd) plays a vital role in the accurate design and safety of weirs,
spillways, and dams. In the last decade, Soft Computing (SC) models, which showed …

Sediment and deposition are among the main problems in dam engineering and other
related fields. Because of the numerous advantages of numerical modeling, effects of …

This research aims to estimate the overflow capacity of a curved labyrinth using different
intelligent prediction models, namely the adaptive neural-fuzzy inference system, the …

Finding an optimal design for hydraulic structures and devices, which work together in
irrigation networks, can be formulated as a multi-objective optimization problem. In this …

Weirs serve the dual purpose of flow measurement and flow regulation in open channels. In
the past, weirs of improved plan form have been used to increase the discharge through the …

This study evaluates the effect of the piano key weir's (PKW) shape and type on the flow
efficiency for different inlet and outlet keys width ratios (W i/W o). The study is performed …

Piano-key weirs (PKWs) have gained importance in recent years as an alternative to
conventional weirs for controlling the flow of water in dam rehabilitation projects. PKWs have …

In this paper, for the first time, to model the discharge coefficient of labyrinth weirs, the
evolutionary firefly algorithm (FFA) is used for optimizing the membership functions of the …

Optimization is an interesting method that finds the optimal response (ie, objective function)
by searching the decision variables in the search space. The present study deals with the …
