This study is related to flow measurement structures of asymmetric compound cross section mostly suggested for sediment laden-rivers, streams and wadis. Nine different models of asymmetrical rectangular cross sections were tested for a wide range of discharges. In each model, the stages and corresponding discharges were measured. From these measurements, the average discharges utilizing the Phi-indices Approach were determined. In addition, a multivariable regression model was derived with high accuracy for the prediction of discharge in asymmetric compound channels using five dimensionless parameters.

Multi-media reservoirs depleted by horizontal wells: analysis of pressure behaviours and rate transient accompanied by developing analytical models for flow regimes Al-Rbeawi, Salam (Inderscience Publishers, 2020-01-01) This paper focuses on analysing pressure behaviours and rate transient of multi-porous media formations such as carbonate reservoirs depleted by horizontal wells. Several analytical models (pressure transient and rate transient) have been developed using the well-known dual-porosity models for naturally fractured formations and modified for triple-media formations considering the existence of hydraulic fractures. The solutions of these models demonstrate different flow regimes corresponding to different pro...
Seismic Performance of Integral Bridges as a Function of Foundation Soil Stiffness Dicleli, Murat (2012-09-24) In this study, the effect of foundation soil stiffness on the seismic performance of integral bridges (IBs) is investigated. For this purpose, nonlinear structural models of a two-span IB with four different foundation soil stiffness types (loose, medium, medium-dense and dense sands) are built. In the nonlinear structural models, nonlinear soil-structure interaction including free-field effects is considered. Then, the nonlinear time history analyses of the IB models are conducted using a set of ground mot...
Sensitivity Analysis of Major Drilling Parameters on Cuttings Transport during Drilling Highly-inclined Wells Ozbayoglu, E. M.; Miska, S. Z.; Takach, N.; Reed, T. (Informa UK Limited, 2009-01-01) In this study, a layered cuttings transport model is developed for high-angle and horizontal wells, which can be used for incompressible non-Newtonian fluids as well as compressible non-Newtonian fluids (i.e., foams). The effects of major drilling parameters, such as flow rate, rate of penetration, fluid density, viscosity, gas ratio, cuttings size, cuttings density, wellbore inclination and eccentricity of the drillsting on cuttings transport efficiency are analyzed. The major findings from this study are,...
Incompressible flow simulations using least squares spectral element method on adaptively refined triangular grids Akdağ, Osman; Sert, Cüneyt; Department of Mechanical Engineering (2012) The main purpose of this study is to develop a flow solver that employs triangular grids to solve two-dimensional, viscous, laminar, steady, incompressible flows. The flow solver is based on Least Squares Spectral Element Method (LSSEM). It has p-type adaptive mesh refinement/coarsening capability and supports p-type nonconforming element interfaces. To validate the developed flow solver several benchmark problems are studied and successful results are obtained. The performances of two different triangular ...
Evaluation of separate channel methods for discharge computation in asymmetric compound channels Al-Khatib, Issam A.; Dweik, Adel A.; Göğüş, Mustafa (2012-04-01) Some experimental results from the Fluid Mechanics Water Channel Facility at Birzeit University, Birzeit, Palestine, were used for computing discharge using separate channel methods in asymmetrical compound channels with varying floodplain widths and step heights. Three assumed interface planes (vertical, horizontal and diagonal) between the main channel and the floodplain subsections were considered. Then discharge values in the subsections and in the whole cross-section were evaluated. None of the separat...
