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 ...

Interface structure and flux laws in a natural double-diffusive layering

Alfred Johny Wüest, Martin Schmid

The diffusive regime of double-diffusive convection generates staircases consisting of thin high-gradient interfaces sandwiched between convectively mixed layers. Simultaneous microstructure measurements of both temperature and conductivity from the stairc ...

Diffusive-type of double diffusion in lakes - a review

Alfred Johny Wüest, Martin Schmid

This chapter is a contribution in honour of Gerhard H Jirka, who has been fascinated by the amazing variety of small-scale structures that nature surprises us with, particularly in stratified natural waters. Here, we focus on the diffusive regime of double ...

Methane formation and future extraction in Lake Kivu

Alfred Johny Wüest, Natacha Tofield-Pasche, Martin Schmid

This chapter summarises the current knowledge on the vertical distribution of methane (CH4) and its formation in Lake Kivu. Additionally, we review the objectives and restrictions under consideration for sustainable extraction (safe, environmentally accept ...

Nutrient cycling in Lake Kivu

Alfred Johny Wüest, Natacha Tofield-Pasche, Martin Schmid

This chapter summarizes the knowledge on mixing and transport processes in Lake Kivu. Seasonal mixing, which varies in intensity from year to year, influences the top ∼65 m. Below, the lake is permanently stratified, with density increasing stepwise from ∼ ...

Stratification, mixing and transport processes in Lake Kivu

Alfred Johny Wüest, Martin Schmid

This chapter summarizes the knowledge on mixing and transport processes in Lake Kivu. Seasonal mixing, which varies in intensity from year to year, influences the top â ¼65 m. Below, the lake is permanently stratified, with density increasing stepwise from ...

Comment on An additional challenge of Lake Kivu in Central Africa - upward movement of the chemoclines by Finn Hirslund

Alfred Johny Wüest, Martin Schmid

In a paper published earlier this year, Finn Hirslund suggested to release degassed deepwater from methane harvesting to the surface layer of Lake Kiwi in order to counteract an observed slow rising of the chemoclines in the lake. In this comment, we prese ...

Modeling of temperature and turbidity in a natural lake and a reservoir connected by pumped-storage operations

Alfred Johny Wüest, Martin Schmid

Pumped-storage (PS) systems are used to store electric energy as potential energy for release during peak demand. We investigate the impacts of a planned 1000 MW PS scheme connecting Lago Bianco with Lago di Poschiavo (Switzerland) on temperature and parti ...
