Adapting tilt corrections and the governing flow equations for steep, fully three-dimensional, mountainous terrain

Wolf Hendrik Huwald, Marc Parlange, Holly Jayne Oldroyd, Eric Richard Pardyjak

In recent studies of atmospheric turbulent surface exchange in complex terrain, questions arise concerning velocity-sensor tilt corrections and the governing flow equations for coordinate systems aligned with steep slopes. The standard planar-fit method, a ...

Soil surface morphology evolution under spatially non-uniform rainfall

David Andrew Barry, Andrea Rinaldo, Mohsen Cheraghi

We evaluated the applicability of a large-scale river network evolution model used to simulate morphological changes of a laboratory-scale landscape on which there were no visible rills. Previously, such models were used only at the landscape scale, or in ...

Buoyant Turbulent Kinetic Energy Production in Steep-Slope Katabatic Flow

Marc Parlange, Chad Higgins, Holly Jayne Oldroyd, Eric Richard Pardyjak

We develop several critical concepts that should be considered when interpreting, modelling and designing future experiments for flows over sloping terrain. Vertical buoyancy fluxes in katabatic flows can be positive and a source of turbulent kinetic energ ...

Image Based Relighting of Cultural Artifacts

Niranjan Thanikachalam

By incorporating computational methods into the image acquisition pipeline, computational photography has opened up new avenues in the representation and visualization of real world objects in the digital world. For example, we can sample a scene under a f ...

Mountain Snow Distribution and how it may Change in the Future

Michael Lehning, Wolf Hendrik Huwald

The spatial distribution of snow in the mountains is highly heterogeneous, and processes behind this heterogeneity are not yet understood quantitatively. Based on (i) increasing accuracy and spatial coverage of remotely sensed snow depth maps, which have b ...

Modelling wet snow avalanche runout to assess road safety at a high-altitude mine in the central Andes

Nander Wever

Mining activities in cold regions are vulnerable to snow avalanches. Unlike operational facilities, which can be constructed in secure locations outside the reach of avalanches, access roads are often susceptible to being cut, leading to mine closures and ...

Implementation and Performance Analysis of the Lightning Potential Index as a Forecasting Tool

Martina Lagasio

Severe weather events are responsible for hundreds of fatalities and millions of euros of damage every year in the Mediterranean basin. Lightning activity is a characteristic phenomenon of severe weather and often accompanies torrential rainfall, which und ...

Buoyant turbulence kinetic energy (TKE) production in katabatic flow despite stable thermal stratification

Marc Parlange, Chad Higgins, Holly Jayne Oldroyd, Eric Richard Pardyjak

As micrometeorological research shifts to increasingly non-idealized environments, the lens through which we view classical atmospheric boundary layer theory must also shift to accommodate unfamiliar behavior. We present observations of katabatic flow over ...

Very high-resolution digital elevation models for multi-scale analysis in landscape genomics (GENESCALE)

Stéphane Joost

At which spatial scale can selection be tracked? Very high-resolution environmental and genome-wide molecular characterization in Arabis alpina shall indicate if local adaptation acts locally or globally. Though termed local in the scientific jargon, adapt ...

Fixed-wing Micro Aerial Vehicle for Accurate Corridor Mapping

Jan Skaloud, Martin Rehak

In this study we present a Micro Aerial Vehicle (MAV) equipped with precise position and attitude sensors that together with a pre-calibrated camera enables accurate corridor mapping. The design of the platform is based on widely available model components ...
