Multiscale Very High Resolution Topographic Models in Alpine Ecology: Pros and Cons of Airborne LiDAR and Drone-Based Stereo-Photogrammetry Technologies

Stéphane Joost, Estelle Rochat, Kevin Leempoel, Annie Sandrine Guillaume, Aude Rogivue

The vulnerability of alpine environments to climate change presses an urgent need to accurately model and understand these ecosystems. Popularity in the use of digital elevation models (DEMs) to derive proxy environmental variables has increased over the p ...

Development of overturning circulation in sloping waterbodies due to surface cooling

Alfred Johny Wüest, Damien Bouffard, Hugo Nicolás Ulloa Sánchez, Tomy Doda, Cintia Luz Ramon Casanas

Cooling the surface of freshwater bodies, whose temperatures are above the temperature of maximum density, can generate differential cooling between shallow and deep regions. When surface cooling occurs over a long enough period, the thermally induced cros ...

Soil Moisture Estimation by SAR in Alpine Fields Using Gaussian Process Regressor Trained by Model Simulations

Jean-Philippe Thiran, Jelena Stamenkovic

In this paper, we address the problem of retrieving soil moisture over a grassland alpine area from Synthetic Aperture Radar (SAR) data using a statistical algorithm trained by simulations of a physical model. A time series of C-band VV-polarized Wide Swat ...

Impacts of wave and tidal forcing on 3D nearshore processes on natural beaches. Part II. Sediment transport

David Andrew Barry, Roham Bakhtyar

This is the second of two papers on the 3D numerical modeling of nearshore hydro- and morphodynamics. In Part I, the focus was on surf and swash zone hydrodynamics in the cross-shore and longshore directions. Here, we consider nearshore processes with an e ...

Quantifying snowfall and avalanche release synchronization: a case study

Paolo Perona, Benoît Crouzy, Betty Sovilla, Romain Forclaz

We quantify the synchronization between snowfall and natural avalanches in relation to terrain properties at the detachment zone. We analyze field statistics of 549 avalanche events in terms of slope, aspect, timing, coordinate, and release area, identifie ...

Street networks in relation to landforms: Implications for fast-growing cities

Nahid Mohajeri Pour Rayeni

In addition to socio-economic factors, major landforms may affect the city structure and urban form. Here we show that landforms have significant effects on the city shape and street patterns of the fast-growing Iranian cities of Dezful (a river) and Khorr ...

Modelling wind-driven rain on buildings in urbanized area using 3-D GIS and LiDAR datasets

Luca Rossi, François Golay, Sylvain Coutu, Claudio Magalhaes Carneiro, Pauline Emery, Vera Wyrsch

This study investigated the distribution of the fraction of rainfall intercepted by the facades of buildings located in an urbanized area. We used the frequently used semi-empirical standard ISO-15927-3 to simulate Wind-Driven Rain on facades. The implemen ...

Stochastic dynamics of snow avalanche occurrence by superposition of Poisson processes

Paolo Perona, Benoît Crouzy

We study the dynamics of systems with deterministic trajectories randomly forced by instantaneous discontinuous jumps occurring according to two different compound Poisson processes. One process, with constant frequency, causes instantaneous positive rando ...
