Rimkus, Stefan

Education & Occupation

• Research assistant at the Institute of Environmental Engineering, Chair of Hydrology and Water Resources Management (since 2006)
• Master in Environmental Science at the ETH Zurich, 2006 [Thesis title: Modelling distributed melt on Haut Glacier d’Arolla using an enhanced temperature-index approach: testing the model sensitivity and analysis of the spatial-temporal variability of the input data]

Projects & Research Interests

TOPKAPI-ETH [TOPographic Kinematic wave APpoximation and Integration]

• A physically oriented, fully distributed hydrological model. Revision, modification, and extension of the program code of the original TOPKAPI model provided by Prof. Todini and others in the areas snow- and ice melt, evapotranspiration, infiltration, interception, etc. as well as investigating the resulting changes in the model behaviour

APUNCH [Advanced Process UNderstanding and prediction of hydrological extremes and Complex Hazards]

• The goal of APUNCH is to gain a comprehensive and process chain based insight into the response of Alpine watersheds hit by storm rainfall events. In this context the project is concerned with distributed precipitation, weather forecast, landslides, sediment transport, and dyke breaches. For more information I refer to the APUNCH Project Homepage. APUNCH is as well part of the SwissExperiment Project.

Glaciology

• Focusing on the influence of the input data quality on the performance of glacier melt models and the modeling of glacier bed-surface topography
