INTRODUCTION The objective of this study is to provide a synthesis of the pertinent design criteria for submerged bendway weirs. The technical paper is an extension of previous research conducted by the National Center for Computational Hydroscience and Engineering (NCCHE) at the University of Mississippi on the hydrodynamic effects on flow characteristics and effectiveness of submerged bendway...

bendway weirs are an important tool in multi-purpose erosion control and are implemented to control erosion, restore streams, and improve habitat. these structures create a hydraulic effect that reduces erosion on the outer bank of a bend by reducing flow velocities near the outer bank and reduce the concentration of currents on the outer bank creating better current alignment through the bend....

While there are a wide range of design recommendations for using rock vanes and bendway weirs as streambank protection measures, no comprehensive, standard approach is currently available engineers to evaluate their hydraulic performance before construction. This study investigates 2D numerical modeling an option predicting the vane weir structure designs protection. We used Sedimentation River...

Truncated sharp crested weirs are used to measure flow rate and control upstream water surface in irrigation canals and laboratory flumes. The main advantages of such weirs are ease of construction and capability of measuring a wide range of flows with sufficient accuracy. Artificial neural networks (ANNs) and genetic programming (GP) have recently been used for estimation of hydraulic data. In...

Long crested weirs are gaining popularity amongst the hydraulic engineers owing to obvious hydraulic advantage of flow magnification. These weirs can pass much higher floods from the available width of a natural water course. Such weirs may also be introduced in water treatment plants for mixing of chemicals. This paper discusses the advantages of long crested weirs, such as duckbill and labyri...
