Lined channels with trapezoidal, rectangular and triangular sections are the most common
manmade canals in practice. Since the construction cost plays a key role in water …

Characterizing flood-related hazards has mostly relied on deterministic approaches or,
occasionally, on particular uncertainty sources, resulting in fragmented approaches. To …

Abstract In this study, Computational Fluid Dynamics software (ANSYS Fluent) is used to
investigate the turbulence and flow characteristics around spur dike in an open channel …

Flow duration curve represents the percentage of time that a river flow is equal to or greater.
As these curves provide a direct response to the behavior of water resources in a basin …

Abstract Application of Colebrook-White (CW) relation for calculating Darcy-Weisbach (DW)
friction factor has been widely accepted in literature. However, its implicit formation made it …

Estimation of flow resistance coefficients plays an inevitable role in open‐channel flows in
hydraulic modeling and water resources engineering. Despite many equations and methods …

The study of water surface profiles is beneficial to various applications in water resources
management. In this study, two artificial intelligence (AI) models named the artificial neural …

Estimation of bridge backwater has been one of practical challenges in hydraulic
engineering for decades. In this study, Genetic Programming (GP) has been applied for …

The reach-average impacts of frictional forces, which retard flows in man-made channels
and natural streams, are basically taken into account by flow resistance coefficients. These …
