Applied System Analysis

The research group Applied System Analysis aims at investigating interactions between physical forcing, geochemical cycling, and ecology in aquatic ecosystems. The work is focused on identifying, quantifying and predicting human impacts on these systems. For this purpose, specifically acquired datasets as well as datasets available in literature and online databases are analyzed using analytical and statistical methods. Models of varying complexity, ranging from simple box models to three-dimensional numerical simulations, are developed and applied. Recent consulting projects include impacts of pumped-storage operations, heat pumps, and methane extraction facilities on lakes.

Current Projects

The deepest lake of the world still hides many mysteries in its abysses. Some of them could be revealed thanks to long-term observations.
The intricacies of Lake Kivu and of the methane stored in its deep waters could easily keep an entire research institute busy. Our research aims at creating the knowledge needed to support a sustainable and safe exploitation of the methane resource.
Climate change affects lake ecosystems. We investigate the complex interactions in the lake-climate system with global data analysis and local case studies.
The chemistry and biology of lakes is strongly influenced by physical transport processes. We use coupled physical-geochemical models to understand these complex interactions.
We assess the environmental impacts of hydropower plants to support a sustainable development of this energy resource.
Lakes store large amounts of heat. To what extent can this heat be used to replace the use of fossil fuels or electricity for heating and cooling purposes?
The interactions of different chemical and microbial processes in lake sediments can be surprisingly complex. Numerical models help to shed light on these interactions.
What happens if two lakes are connected by a pumped-storage system?

Tools

A one-dimensional physical lake model that can be coupled to biogeochemical models
A tool for modelling diagenetic processes in lake sediments
