Experimental study on tsunamis generated by landslides

Christophe Ancey, Zhenzhu Meng, Ivan Maeder

Tsunami generated by landslides is one of the major threats to populations in coastal areas. A recent example is the 2017 Nuugaatsiaq tsunami. The village in Greenland was partially swept by a tsunami created by a landslide that fell into the Karrat Fjord. ...

Validation of hydraulic design of the Ritom compensation basin

Giovanni De Cesare, Samuel Luke Vorlet, Jakob Siedersleben

Based on the Water Protection Act of 2013, severe issues caused by the rapid change of water discharge (hydropeaking) must be reduced by operators of hydroelectric power plants in Switzerland. Therefore, a new generation of regulating basins is under const ...

Convection in Lakes

Alfred Johny Wüest, Damien Bouffard

Lakes and other confined water bodies are not exposed to tides, and their wind forcing is usually much weaker compared to ocean basins and estuaries. Hence, convective processes are often the dominant drivers for shaping mixing and stratification structure ...

GRUN: an observation-based global gridded runoff dataset from 1902 to 2014

Gionata Ghiggi, Vincent Humphrey

Freshwater resources are of high societal relevance, and understanding their past variability is vital to water management in the context of ongoing climate change. This study introduces a global gridded monthly reconstruction of runoff covering the period ...

Differential Heating Drives Downslope Flows that Accelerate Mixed-LayerWarming in Ice-Covered Waters

Alfred Johny Wüest, Damien Bouffard, Hugo Nicolás Ulloa Sánchez, Kraig Bates Winters

In ice-covered lakes, penetrative radiation warms fluid beneath a diffusive boundary layer, thereby increasing its density and providing energy for convection in a diurnally active, deepening mixed layer. Shallow regions are differentially heated to warmer ...

Application of an Ensemble Kalman filter to a semi-distributed hydrological flood forecasting system in alpine catchments

Giovanni De Cesare, Javier García Hernández, Alain Tommy Foehn, Anne Schwob

One of the key success factor for hydrological forecasts is the establishment of initial conditions that represent well the conditions of the simulated basin at the beginning of the forecast. Real-time Data Assimilation (DA) has been shown to allow improvi ...

Space and time predictions of schistosomiasis snail host population dynamics across hydrologic regimes in Burkina Faso

Andrea Rinaldo, Theophile Mande, Francisco Javier Perez Saez

The ecology of the aquatic snails that serve as obligatory intermediate hosts of human schistosomiasis is driven by climatic and hydrological factors which result in specific spatial patterns of occurrence and abundance. These patterns in turn affect, join ...

Catchment drainage network scaling laws found experimentally in overland flow morphologies

David Andrew Barry, Andrea Rinaldo, Paolo Perona, Mohsen Cheraghi

The scaling relation between the drainage area and stream length (Hack’s law), along with exceedance probabilities of drainage area, discharge and upstream flow network length are well known for channelized fluvial regions. We report here on a laboratory e ...
