Laboratory Investigation of Sand and Water Inflow into a Hole of under-waterway Tunnels
Author(s) Fahmy Salah Fahmy Abdelhaleem, PhD Esam Eldeen Yousry Helal, PhD Abstract The effects of a cracked tunnel underneath a canal bed on water and sand inflow through the tunnel hole and distortion of the canal bed were experimentally examined. A circular...
Experimental Study on the Effect of Sediment Concentration on Trapezoidal Hydraulic Uump
Author(s) Saber Ebrahimiyan, MEng Hooman Hajikandi, PhD Mahmood Shafai Bejestan, PhD Saeed Jamali, PhD Ebrahim Asadi, PhD Abstract The effect of suspended sediment concentration on the characteristics of a hydraulic jump in a symmetrical trapezoidal channel was...
Boundary Shear Distribution in a Compound Channel with Differential Roughness
Author(s) Kamalini Devi, PhD Kishanjit Kumar Khatua, PhD Abstract This paper demonstrates the influence of differential roughness on the boundary shear distribution for compound open channels. A mathematical relationship is derived between the percentage shear...
Maximum Shear-Stress Method for Stable Channel Design
Author(s) Narendra Patel; Amin Mohebbi, M.ASCE; Chyan-Deng Jan, F.ASCE; and Junke Guo, M.ASCE Abstract Stable channel design is important for conveying water among stakeholders in a safe and cost-effective manner. The current design methods include the regime...
Hydraulics of Seepage from Trapezoidal Channels
Author(s) Rajesh Kumar Mahato and Subhasish Dey, M.ASCE Abstract A tractable analytical solution for steady-state two-dimensional seepage from a trapezoidal channel in a homogeneous, isotropic porous medium of considerable depth is presented. The analysis is...
Neural Network Prediction of Alluvial Stream Bedforms
Author(s) David C. Froehlich, Ph.D., P.E., D.WRE, M.ASCE Abstract Substantial laboratory, field, and theoretical studies have been carried out by many to understand alluvial stream bedform origin, their shapes, equilibrium with the flow, and their depositional...
Experimental study of effects of riverbed composition on the riverbank erosion process
Authors Qiang Li, BEng Lu Wang, PhD Xudong Ma, PhD Ruihua Nie, PhD Abstract Riverbank erosion is a common natural river process that threatens the security of instream structures, as well as public and private property. In this study, two sets of tests were...
Sediment Deposition and Distribution Modelling in Reservoirs: Current Trends and Prospects
Authors Arnab Das, MTech Ashok Kumar Gupta, PhD, FNAE Renji Remesan, PhD, FHEA Abstract Global and regional challenges related to river basin water scarcity can effectively be managed through improved reservoir operations and reservoir sedimentation control. It...
