Evolution of stream and lake water temperature under climate change

Alfred Johny Wüest, Damien Bouffard, Wolf Hendrik Huwald, Adrien Michel, Bettina Schaefli, Carl Love Mikael Råman Vinnå, Martin Schmid

This report presents past observations and projects the future development of water temperature in Swiss lakes and rivers. Projections are made until the end of the 21st century using the CH2018 climate scenarios. Besides climate change effects on temperat ...

On the role of local depth and latitude on surface warming heterogeneity in the Laurentian Great Lakes

Sebastiano Piccolroaz, Marco Toffolon, Elisa Calamita

Lake surface water temperature (LSWT) responds rapidly to changes in climatic variables. This response is heterogeneous in space and its spatial distribution is primarily influenced by lake bathymetry and latitude. Such heterogeneity is not captured by one ...

Bathymetry and latitude modify lake warming under ice

Damien Bouffard, Hugo Nicolás Ulloa Sánchez, Tomy Doda, Cintia Luz Ramon Casanas, Kraig Bates Winters

In late winter, solar radiation is the main driver of water motion in ice-covered lakes. The resulting circulation and mixing determine the spatial distribution of heat within the lake and affect the heat budget of the ice cover. Although under-ice lake wa ...

The Red Harmful Plague in Times of Climate Change: Blooms of the Cyanobacterium Planktothrix rubescens Triggered by Stratification Dynamics and Irradiance

Alfred Johny Wüest, Bieito Fernandez Castro

Planktothrix rubescens is a harmful planktonic cyanobacterium, forming concentrated metalimnetic populations in deep oligo- and mesotrophic lakes, even after successful restoration. In Lake Zurich (Switzerland), P. rubescens emerged as a keystone species w ...

Field characterization of the negatively buoyant inflow of the Rhône River into Lake Geneva

David Andrew Barry, Ulrich Lemmin, Koen Blanckaert

River inflows have a major influence on lake and reservoir water quality through their input of momentum, heat, oxygen, sediment, nutrients and contaminants. The fate of these components is controlled by the hydrodynamic processes at the interface between ...

Effects of biogenic surfactants on the spatial variability of surface water temperature under low-wind conditions

David Andrew Barry, Mehrshad Foroughan

Natural slicks are manifested by changing reflective properties of water surfaces through inhibition of wave-growth and damping short gravity-capillary waves. Such influence on near-surface hydrodynamics can in turn affects the air-water exchange of moment ...

The Importance of Systematic Spatial Variability in the Surface Heat Flux of a Large Lake: A Multiannual Analysis for Lake Geneva

David Andrew Barry, Ulrich Lemmin, Andrea Cimatoribus, Abolfazl Irani Rahaghi

The spatiotemporal surface heat flux (SurHF) distribution over Lake Geneva, the largest lake in Western Europe, was estimated for a 7‐year period (2008–2014). Data sources included hourly maps of over‐the‐lake assimilated meteorological data from a validat ...

Oxygen consumption in seasonally stratified lakes decreases only below a marginal phosphorus threshold

Alfred Johny Wüest, Robert Vincent Schwefel

Areal oxygen (O-2) consumption in deeper layers of stratified lakes and reservoirs depends on the amount of settling organic matter. As phosphorus (P) limits primary production in most lakes, protective and remediation efforts often seek to reduce P input. ...
