The Case for Sihl Dam

This chapter presents a case and results that were undertaken at the request of the Swiss Risk Engineering Company, regarding the potential consequences of a virtual Sihl Dam break event. Note that the modeling is limited to a ‘worst case scenario’ describing a full destruction of the dam wall within a short time span and the consequent release of the whole water reservoir volume. To compare results and show the strength of the proposed model and the associated decision support system, a similar consequence assessment published on the Internet by the Polizei department, Zurich was used as a frame of reference.
