Giant lacustrine pockmarks with subaqueous groundwater discharge and subsurface sediment mobilization

Subsurface fluid flow in oceans and lakes affects bathymetric morphology, sediment distribution, and water composition. We present newly discovered giant lacustrine pockmarks in Lake Neuchatel (up to 160m diameter and 30m deep) that rank among the largest ...

Environmental considerations on solar disinfection of wastewater and the subsequent bacterial (re)growth

César Pulgarin, Stefanos Giannakis

In this work, solar disinfection of wastewater was studied, focusing on the effect of selected environmental variables, namely light intensity, continuous/intermittent light delivery, and post-irradiation storage as well as dilution in lake water. These va ...

Wind variability and sheltering effects on measurements and modeling of air-water exchange for a small lake

Fernando Porté Agel, Corey Dean Markfort

Lakes with a surface area of less than 10 km^2 account for over 50% of the global cumulative lake surface water area, and make up more than 99% of the total number of global lakes, ponds, and wetlands. Within the boreal regions as well as some temperate an ...

Prediction of surface temperature in lakes with different morphology using air temperature

Alfred Johny Wüest, Sebastiano Piccolroaz, Marco Toffolon, Martin Schmid

Temperature of the surface layer of temperate lakes is reconstructed by means of a simplified model on the basis of air temperature alone. The comparison between calculated and observed data shows a remarkable agreement (Nash-Sutcliffe efficiency indices a ...

Surface heat flux variability of a large lake: Lake Geneva, Switzerland

David Andrew Barry, Ulrich Lemmin, Damien Bouffard, Abolfazl Irani Rahaghi

The heat budget of a lake is a fundamental component of physical limnology, and is strongly dependent on the surface heat flux. However, the surface energy exchange depends on several factors, making it difficult to estimate. In this study we employed seve ...

Heat flux modifications related to climate-induced warming of large European lakes

Alfred Johny Wüest, Martin Schmid

Within the last decades, the water temperature of several European lakes has risen. It is assumed that these temperature increases are due to a reconfiguration of the heat-balance components. This study explores the dominant modifications of heat exchange ...

Modelling Lake Kivu water level variations over the last seven decades

Alfred Johny Wüest, Martin Schmid

This study aimed at analysing the hydrological changes in the Lake Kivu Basin over the last seven decades with focus on the response of the lake water level to meteorological factors and hydropower dam construction. Historical precipitation and lake water ...

Accelerated Water Quality Improvement during Oligotrophication in Peri-Alpine Lakes

Alfred Johny Wüest, Beat Mueller

Monitoring of four eutrophic Swiss lakes undergoing oligotrophication during more than 25 years (i.e., gradually decreasing nutrient loading, productivity, and associated symptoms of eutrophication) revealed that phosphorus (P) net sedimentation rates (the ...

Lake surface temperatures in a changing climate: a global sensitivity analysis

Alfred Johny Wüest, Martin Schmid, Stefan Hunziker

We estimate the effects of climatic changes, as predicted by six climate models, on lake surface temperatures on a global scale, using the lake surface equilibrium temperature as a proxy. We evaluate interactions between different forcing variables, the se ...
