CADAM EUROPEAN CONCERTED ACTION ON DAM-BREAK MODELLING

摘要

The nature of legislation in Europe addressing risk assessment for dam safety isrnvaried, as are the numerical codes and techniques applied to predict the catastrophicrnfailure of a dam and subsequent flood inundation. CADAM – a European ConcertedrnAction on Dam-break Modelling – was established to gather and review knowledgernand practice in order to optimise modelling technique and approach. The project runsrnfor a two year period between February 1998 and January 2000. Topics coveredrninclude analysis and modelling of flood wave propagation, breaching ofrnembankments and sediment effects. The programme of study is such that thernperformance of modelling codes are compared against progressively more complexrnconditions from simple flume tests through physical models of real valleys and finallyrnto real dam-break cases. Conclusions from the study will be presented at a closingrnmeeting to be held in Zaragoza, Spain in November 1999.
