Towards Long-Term Collective Experiments

Francesco Mondada, Michael Bonani, Philippe Rétornaz, Florian Christopher Vaussard, Steven Adriaan Roelofsen, François Rey

It is often challenging to manage the battery supply when dealing with a fleet of mobile robots during long experiments. If one uses classical recharge stations, then agents are immobilized during the whole recharge process. In this study, we present a nov ...

Capillary effect on watertable fluctuations in unconfined aquifers

David Andrew Barry

Parlange and Brutsaert [1987] derived a modified Boussinesq equation to account for the capillary effect on watertable dynamics in unconfined aquifers. Barry et al. [1996] solved this equation subject to a periodic boundary condition. Their solution shows ...

Assessment of bioremediation potential and monitoring of biological reductive dechlorination in sites contaminated with chlorinated ethenes

Christof Holliger, Pierre Rossi, Sonia Estelle Tarnawski

Chlorinated ethenes (CEs), such as perchloroethene (PCE) and trichloroethene (TCE), are one of the most common class of groundwater contaminants. Aquifers are considered nowadays as dynamic ecosystems, showing multiple interactions between the physical, ch ...

Analysis of flood-reduction capacity of hydropower schemes in an Alpine catchment area by semidistributed conceptual modeling

Anton Schleiss, Martin Peter Bieri

The simulation of run-off in Alpine catchment areas is essential for the optimal operation of high head storage hydropower plants (HPPs) under normal flow conditions, but also in case of flood events. A conceptual semidistributed numerical approach is pres ...

Biogeochemical processes and geotechnical applications: progress, opportunities and challenges

Lyesse Laloui

Consideration of soil as a living ecosystem offers the potential for innovative and sustainable solutions to geotechnical problems. This is a new paradigm for many in geotechnical engineering. Realising the potential of this paradigm requires a multidiscip ...

Improved rain rate estimation by combining radars, rain gauges and microwave links

Blandine Bianchi

The measurement of rainfall and its prediction at short lead times (often referred to as nowcasting) have important implications in hydrometeorology, and improving their accuracy may have an impact on various human activities. Indeed, the importance of now ...

Capillary Effects on Groundwater Waves in Unconfined Coastal Aquifers

David Andrew Barry

Various types of Boussinesq model exist, including those that account for finite-depth aquifers and capillary effects. Such models are used to simulate propagation of groundwater waves (watertable fluctuations) due to, for example, tides. However, discrepa ...

MATHICSE Technical Report : A quasi-optimal sparse grids procedure for groundwater flows

Fabio Nobile, Lorenzo Tamellini

In this work we explore the extension of the quasi-optimal sparse grids method proposed in our previous work \On the optimal polynomial ap- proximation of stochastic PDEs by Galerkin and Collocation methods" to a Darcy problem where the permeability is mod ...

Assessing the Bacterial Ecology of Organohalide Respiration for the Design of Bioremediation Strategies

Noam Shani

Groundwater is essential for human activities and is sometimes referred to as a non-renewable resource in the same way as oil and gas. During the past century, precious groundwater reserves worldwide have been threatened by anthropogenic release of chemica ...

Recycler l'eau à Mexico: la station d'épuration, un générateur d'opportunités urbaines

Edouard Philippe, Steffan Heath

Depuis un demi-siècle, Mexico et ses millions d'habitants font face à une surexploitation massive des ressources hydriques locales. L'eau souterraine de l'aquifère, qui constitue la source principale d'approvisionnement en eau de la ville, se trouve dans u ...
