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 …

Probabilistic analyses facilitate the incorporation of inherent uncertainties in dam safety
evaluation. Their application is limited due to the high computational burden, especially for …

In the present research, three different data-driven models (DDMs) are developed to predict
the discharge coefficient of streamlined weirs (C dstw). Some machine-learning methods …

Labyrinth weirs are complex hydraulic structures. They have been widely used as a water
regulator and to increase discharge in channels and spillway dams. Labyrinth weirs are an …

The hydraulic jump phenomenon plays a significant role in dissipating the energy of the
upstream current in either natural or artificial waterways. River's bed roughness is defined as …

Dam safety assessment is typically made by comparison between the outcome of some
predictive model and measured monitoring data. This is done separately for each response …

Side weirs, referred to as lateral weirs, are flow diversion hydraulic structures frequently
used in canal systems, irrigation-drainage systems, and urban sewage systems as a head …

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 …

Approximately 70,000 Spanish off-stream reservoirs, many of them irrigation ponds, need to
be evaluated in terms of their potential hazard to comply with the new national Regulation of …

In the present research, the reliability-based design optimization (RBDO) of labyrinth weirs
has been investigated. The optimization problem is formulated such that the optimal shape …
