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 ...

Hydrological monitoring and modeling of an alpine catchment

Andrea Rinaldo, Marc Parlange, Steven Vincent Weijs, Raphaël Mutzner

Since 2008 we have been monitoring a watershed in the alps to assess the impact of the spatial heterogeneity of meteorological variables over a complex terrain and identify the mechanisms generating streamflow. The study area is located in the Swiss Alps a ...

The geomorphic origin of recession curves

Nevena Tomasic

An important study domain in hydrology is dedicated to understand how the spatial organization of river networks is reflected in the hydrologic response to rainfall inputs (Biswal and Marani, 2010). Base flow (or recession flow) is the discharge rate in a ...

Technical note: Preliminary estimation of rockfall runout zones

Vincent Labiouse

Rockfall propagation areas can be determined using a simple geometric rule known as shadow angle or energy line method based on a simple Coulomb frictional model implemented in the CONEFALL computer program. Runout zones are estimated from a digital terrai ...

Multiscale analysis of high resolution digital elevation models using the wavelet transform

Michaël Kalbermatten

At the end of the nineties the emergence of high resolution (1 m) digital elevation models (DEMs) settled the context of high precision geomorphological analysis. These new elevation models permitted to reveal structures that remained heretofore undetectab ...

Integrating river cross section measurements with digital terrain models for improved flow modelling applications

Paolo Perona

An important element in hydraulic modelling is the topography data of the riverbed and the floodplain area. The latter can be obtained directly from digital terrain models (DTM), but the measurement of the riverbed topography is not straightforward. Since ...

Gestion dynamique des échelles de données raster dans un environnement interactif

Benoit Le Bocey

Scale and resolution have long been key issues of geography. In recent years, the rapid development of desktop or Internet Geographic Information Systems (GIS) has forced a more precise consideration of these concepts. This research focuses on fitting the ...

In-flight quality assessment and data processing for airborne laser scanning

Philipp Schär

One of the main problems of today's Airborne Laser Scanning (ALS) systems is the lack of reliable data QA/QC (Quality Assurance/ Quality Control) within or shortly after the airborne survey campaign. This thesis presents the development of methods to perfo ...
