LW-Project: Quantitative aggregation of individual hazards to an overall risk for well catchments

Department of Hydromechanics and Modelling of Hydrosystems

Funded by the Zweckverband Landeswasserversorgung from 1st November 2012 until 30th April 2013


In this project, we will develop a mathematic-stochastic method to quantify the overall risk for well catchments. The goal is find a consistent aggregation for the individual risks from known hazards in the catchment. We will consider the probability of contaminant spills, the uncertain contaminant mass per spill, the concurrence and overlap of events, and the transport in the groundwater from the spill to the well. In transport simulations, we will account for the uncertainty in the hydrogeological description of the well catchment and different release scenarios from instantaneous point-like sources to continuous distributed sources. The unit for total risk will be the failure time (and its statistics) of the water production due to violation of drinking water standards. Special emphasis will be on the expected down time per year and the frequency (annuality) of critical durations of failure.
