Basic experiments were conducted on a large-size broad-crested weir with a rounded corner. Detailed free-surface, velocity, and pressure measurements were performed for a range of flow conditions. The results showed the rapid flow distribution at the upstream end of the weir and next to the weir brink at large flow rates. The flow properties above the crest were analyzed taking into account the...

This study presents a general solution for the radial flow of tracers in naturally fractured reservoirs. Continuous and finite step injection of chemical and radioactive tracers are considered. The reservoir is treated as being composed of two regions: a mobile region where longitudinal dispersion and convection take place and a stagnant region where only diffusion and adsorption are a1 1 owed....

Different flow-altering methods, such as W−Weirs, have been developed to reduce erosion. For this study, we performed two experiments: (1) installing a W−Weir in various positions determine the best angle for placement, and (2) investigating variation of flow patterns bed shear stress distribution 90-degree sharp bend by measuring 3D components velocities, with without where greatest scour dept...

Basic experiments were conducted on a large-size broad-crested weir with an upstream rounded corner. Detailed velocity and pressure measurements were performed for a range of flow conditions. The results showed the rapid flow re-distribution at the upstream end of the weir, as well as next to the weir brink at large flow rates. Assuming non-uniform velocity and nonhydrostatic pressure distribut...

In this study, Gene expression programming (GEP) is employed as a new method for estimating the side weir discharge coefficient. The accuracy of existing equations in evaluating the side weir discharge coefficient is first examined. Afterward, taking into consideration the dimensionless parameters that affect the estimation of this parameter and sensitivity analysis, five different models are p...

Abstract—This study was conducted to evaluate the seismic performance of weir structures using two different approaches: i) design response spectrum with respect to KBC 2009 in Korea and ii) acceleration of time history (PGA, 0.3011 g) obtained from 1994 Northridge earthquake. This paper provided the simple linear elastic 2D plane strain FE model with the material nonlinearity including soil-fo...
