This study investigates incipient motion through controlled flume tests on ... 2026-01-01T00:00:00Z Flood Inundation-Induced Bridge Pressure Scour: Developing New Prediction Equations and Exploring Machine-Learning Methods http://yetl.yabesh.ir/yetl1/handle/yetl/4311600 Flood Inundation-Induced Bridge Pressure Scour: Developing New Prediction Equations and Exploring Machine-Learning Methods Tang, Zihao; Yang, Yifan; Melville, Bruce; Xie, Yushu AbstractBridge pressure scour occurs when the bridge deck is inundated during a flood event, causing significant threats to the stability of local streambeds and bridge foundations. In the present study, new flume experiments were conducted to investigate ... 2026-01-01T00:00:00Z Analytical Modeling of Flow-Induced Pore Pressure and Initial Bedform Deformation in Poroelastic Beds Using Biot’s Theory http://yetl.yabesh.ir/yetl1/handle/yetl/4311599 Analytical Modeling of Flow-Induced Pore Pressure and Initial Bedform Deformation in Poroelastic Beds Using Biot’s Theory Kuo, Yuan-Ching; Huang, Liang-Hsiung AbstractThis paper develops an analytical framework to quantify how flow-induced pore-pressure fields drive initial bedform deformation in soft, saturated porous beds. Starting from Biot’s poroelastic framework, the governing equations are simplified ...Practical ApplicationsThis study develops a simplified analytical model to examine how water flow and wave action generate pore pressure and cause deformation in soft, saturated seabeds. Based on Biot’s poroelastic theory, the model demonstrates that ... 2026-01-01T00:00:00Z Scour due to Submerged Planar Wall Jets: A Model http://yetl.yabesh.ir/yetl1/handle/yetl/4311598 Scour due to Submerged Planar Wall Jets: A Model Dey, Subhasish; Mahato, Rajesh K.; Ali, Sk Zeeshan AbstractIn this study, equilibrium scour formed by submerged planar turbulent wall jets over a sediment bed is modeled. The theoretical framework consists of a flow model coupled with an equilibrium scour model. Using existing experimental data, a single-... 2026-01-01T00:00:00Z
