Threshold modeling of extreme spatial rainfall

Anthony Christopher Davison, Raphaël Mutzner, Emeric Rolland Georges Thibaud

We propose an approach to spatial modeling of extreme rainfall, based on max-stable processes fitted using partial duration series and a censored threshold likelihood function. The resulting models are coherent with classical extreme-value theory and allow ...

Soil Moisture & Snow Properties Determination with GNSS in Alpine Environments: Challenges, Status, and Perspectives

Pierre-André Farine, Jan Skaloud, Cyril Botteron, Steven Vincent Weijs, Jérôme Leclère

Moisture content in the soil and snow in the alpine environment is an important factor, not only for environmentally oriented research, but also for decision making in agriculture and hazard management. Current observation techniques quantifying soil moist ...

Geostatistics of Dependent and Asymptotically Independent Extremes

Anthony Christopher Davison, Emeric Rolland Georges Thibaud, Raphaël Huser

Spatial modeling of rare events has obvious applications in the environmental sciences and is crucial when assessing the effects of catastrophic events (such as heatwaves or widespread flooding) on food security and on the sustainability of societal infras ...

A case study on spatial and temporal hydraulic variability in an alpine gravel-bed stream based on the hydromorphological index of diversity

Anton Schleiss, Walter Gostner, Piotr Parasiewicz

Physical heterogeneity is a major topic in river sciences because it is known to be a key factor for ecological integrity. In this paper, we investigated the hydraulic enviroment in an alpine gravel-bed stream with an unaltered hydrological regime. The stu ...

Modeling the Onset of Shallow Landslides in Partially Saturated Slopes Subjected to Rain Infiltration

Lyesse Laloui, Mathieu Nuth, John Eichenberger

Heavy rainfall can lead to shallow slips on slopes which are often initially in a state of partial water saturation. A multiphysics approach and advanced constitutive modeling are necessary to take into account the physical key processes in partially satur ...

Collaborative Location Privacy with Rational Users

Jean-Pierre Hubaux, Mathias Jacques Jean-Marc Humbert, Reza Shokri, Francisco De Meneses Neves Ramos Dos Santos

Recent smartphones incorporate embedded GPS devices that enable users to obtain geographic information about their surroundings by providing a location-based service (LBS) with their current coordinates. However, LBS providers collect a significant amount ...

Soft Robotics: Challenges and Perspectives

There has been an increasing interest in the use of unconventional materials and morphologies in robotic systems because the underlying mechanical properties (such as body shapes, elasticity, viscosity, softness, density and stickiness) are crucial researc ...

Hierarchy of models for meandering rivers and related morphodynamic processes

Paolo Perona

We review the importance of the physical mechanisms involved in river meandering by comparing some existing linear models and extensions thereof. Such models are hierarchically derived from a common and general mathematical framework and then analyzed with ...
