Abstract: A direct analytical approach is proposed to study the turbulent surface water flow on a slope. Both unplanted ground and grassed ground are investigated by dividing the flow field into two layers—homogenous water ...

Abstract: This study examines low Reynolds number flow over vegetated sloping ground. Instead of using the traditional empirical formula related to resistance or frictional roughness, a new approach is presented by considering the ...

Abstract: Substantial energy losses occur when water flows over vegetated ground. Vegetation enhances surface resistance and decreases flow velocity, which results in energy loss. Since the ground is considered to be permeable, both ...

Abstract: Since porous material is usually of a finite thickness in nature, the effects of periodically nonlinear water waves propagating over a soft poroelastic bed with finite thickness are hence noticed and studied in this work. ...

Abstract: In nature, a soil profile generally consists of several heterogeneous layers. This study is aimed at discussing the interactive problem of oscillatory water waves and flow passing over multilayered soils. The soil behavior ...

Abstract: The two-dimensional (2D) hydraulic analysis of water flow down a slope is crucial. Contrary to past studies, not only the anisotropy of soil but also the vertical component of flow velocity are considered in this study. ...

Abstract: In nature, the ground is usually composed of different soils. To simplify the soil structure, we only consider the case of parallel soil layers with a small inclined angle to the horizontal. When a ground surface without ...

Abstract: Studies on open channel flows generally focus on the flow profiles in the longitudinal direction. When generating the analytical solutions, the simplified governing equations are usually employed by neglecting the vertical ...

Abstract: The problem of the dynamic interaction of water waves, current, and a hard poroelastic bed is dealt with in this study. Finite-depth homogeneous water with harmonic linear water waves passing over a semi-infinite poroelastic ...
