Momentum balance of katabatic flow on steep slopes covered with short vegetation

Marc Parlange, Gabriel George Katul, Eric Richard Pardyjak, Holly Jayne Oldroyd

Katabatic flows over alpine mountainous terrain differ from their forested or bare slope counterparts due to the presence of well-ventilated, short vegetation. The impact of a grass canopy and larger-scale pressure perturbations on the one-dimensional mean ...

Shear-Stress Partitioning in Live Plant Canopies and Modifications to Raupach's Model

Michael Lehning, Benjamin Andreas Walter

The spatial peak surface shear stress on the ground beneath vegetation canopies is responsible for the onset of particle entrainment and its precise and accurate prediction is essential when modelling soil, snow or sand erosion. This study investigates she ...

Tomography-based determination of permeability and Dupuit-Forchheimer coefficient of characteristic snow samples

Sophia Haussener, Marc Schneebeli Zeugin

A tomography-based methodology for the mass transport characterization of snow is presented. Five samples, characteristic for a wide range of seasonal snow, are considered. Their three-dimensional (3-D) geometrical representations are obtained by micro-com ...

Open-loop control of compressible afterbody flows using adjoint methods

Philippe Meliga

The flow past an axisymmetric body is generically unstable to a steady and a time-periodic global instability, the latter being thought to lead the low-frequency unsteadiness of the wake even at larger Reynolds numbers. The present paper examines how the g ...

Mathematical and numerical analysis of a three-dimensional fluid flow model in glaciology

Jacques Rappaz, Adrian Reist

The main goal of this article is to analyze a three-dimensional model for stress and velocity fields in grounded glaciers and ice sheets including the role of normal deviatoric stress gradients. This model leads to a nonlinear system of stationary partial ...
