Numerical Analysis of Apparatus-Induced Dispersion for Density-Dependent Solute Transport in Porous Media

David Andrew Barry, Hong Zhang

The effects of apparatus-induced dispersion on nonuniform, density-dependent flow in a cylindrical soil column were investigated using a finite-element model. To validate the model, the results with an analytical solution and laboratory column test data we ...

A Fast Hybrid Pressure-Correction Algorithm for Simulating Incompressible Flows by Projection Methods

Jiannong Fang

To enforce the conservation of mass principle, a pressure Poisson equation arises in the numerical solution of incompressible fluid flow using the pressure-based segregated algorithms such as projection methods. For unsteady flows, the pressure Poisson equ ...

Biomorphodynamics of river banks in vegetated channels with self-formed width

Paolo Perona

Laboratory and field studies investigating the mutual interaction between riparian vegetation dynamics and river morphodynamics have revealed that riparian vegetation may play an important role in the evolution of channel beds and river banks. In order to ...

3D hydrodynamic modeling of Lake Zurich

A three-dimensional hydrodynamic Z-model was conceived for Lake Zurich (Switzerland, ZH) using the modeling software Delft3D. Calibration was performed on the thermal profile in 2017 at three monitoring stations located in both basins, and was validated on ...

Hydromorphodynamic effects of the width ratio and local tributary widening on discordant confluences

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña, António Heleno Cardoso

River training works performed in the last couple of centuries constrained the natural dynamics of channel networks in locations that include the confluences between tributaries and main channels. As a result, the dynamics of these confluences are currentl ...

SENSITIVITY ANALYSIS OF THE HYDROMORPHOLOGICAL INDEX OF DIVERSITY USING NUMERICAL GENERATED DATA

Anton Schleiss, Severin Stähly, Pierre Bourqui, Christopher Robinson

River restoration has become a priority goal in many countries. The interest in rivers as valuable habitats for floral and faunal diversity and as an ecosystem with important functions has increased. For evaluating the structural changes from a river resto ...

River widening is commonly used as a solution for the rehabilitation of rivers with the main purposes of allowing the river to adjust to its natural dynamics and to improve riparian and instream habitat for flora and fauna, by increasing the heterogeneity ...

CRC Press/Balkema2014

A simple experiment, designed to investigate entrainment in geophysical free-surface flows such as avalanches and debris flows, was performed using a dam break of viscous fluid which travels over a rigid bed until meeting a shallow layer of the same fluid ...

Flow field UVP measurements of a Y-shape outlet structure

Giovanni De Cesare, Alexandre Jean Pachoud

Y-shape outlet structures are used to release the turbine water into a reservoir. Classical design oftenuses a Y-shape over a certain length and with a specific opening angle. Depending on the geometry,especially in turbine mode, significant undesired flow ...
