Numerical study of transient flow dynamics in a prismatic channel with a bed depression

Journal of Hydrology and Hydromechanics
Catastrophic floods triggered by a dam-break pose significant hazards to infrastructure due to transient flows and concentrated structural loads. These hazards are intensified where in-channel structures or variable topography redirect momentum and ...

Evaluación de la eficiencia en disipación de energía en estructuras hidráulicas construidas con gaviones y material reciclado (neumático usado) mediante modelamiento físico a escala reducida

Revista UIS Ingenierías, 2020
Flujos con exceso de energía cinética producen alta velocidad, sobrepresiones y procesos erosivos, en este sentido los disipadores de energía son estructuras hidráulicas que minimizan este efecto. Dichas obras suelen construirse en concreto convencional,

Alluvial fan models in the Cantabrian successions (Cea Group) of the Esla Nappe, Cantabrian Mountains [PDF]

, 2006
The main aim of this paper is to describe two alluvial fan models that have been generated in the Esla Nappe of the Cantabrian Zone during the lower Stephanian. These models have been named Duerna alluvial fan and Peña Verde-Remolina system.

Effects of flow splitters on local scour downstream of type-A trapezoidal piano key weir

Applied Water Science
This study investigates the effectiveness of flow splitters in reducing scour downstream of trapezoidal Piano Key Weirs through a comprehensive experimental study. Three distinct geometries of flow splitters—square, rectangular, and circular—are examined

The effect of gabion steps on the hydraulic jump characteristics downstream of stepped spillways

Water Science
Gabion steps on stepped spillways can be a suitable alternative to solid impermeable steps due to their economic advantages, ease of implementation, stability through water pressure reduction, and energy dissipation.

Prediction of scour profiles downstream of grade control structures via the shear stress and sediment bed curvature model

International Journal of Sediment Research
A new semianalytical model for the prediction of local scour profiles downstream from typical grade-control structures is proposed on the basis of the variation in bed shear stress and the sediment bed curvature concept.

The gravity flow dynamics of submarine fan sedimentation in the Magura Basin of the Western Carpathians (Magura Nappe, Slovakia)

Geologica Carpathica, 2010
The gravity flow dynamics of submarine fan sedimentation in the Magura Basin of the Western Carpathians (Magura Nappe, Slovakia)This article deals with the dynamics of the deep-water gravity flows sedimentation within the Magura Formation. This investigation is based on analysis of the Magura sandstone sedimentary structures studied on the outcrops ...
