This document presents a description of the IMPACT Project Case Study adopted for Theme Area 2, Breach Formation, and Theme Area 3, Flood Propagation. The case study is based upon the failure of Tous Dam and the flooding of Sumacárcel, a small town about 5Km downstream of Tous Dam that broke due to overtopping on October 20, 1982. The event isDam #3 failed due to the strength of the dam and the stress on the dam (the water). In addition, in order for a dam to fail, the dam has to exist. In this case, the dam existed in order to manage the sludge waste produced at the coal preparation plant. The possible reasons behind the failure of the 93m high dam are discussed in the first of a series of two articles on the disaster During the middle of the last century, the US Bureau of Reclamation(USBR) built dams to help control flooding, improve irrigation and provide power and recreational areas.
