特大洪水演变过程及不确定性研究项目专题(IMPACT)之WP2专题(即溃决形成专题)的重点是通过对大坝或防水堤的研究来提高预测溃决形成的能力。其核心工作是将现场试验和室内试验(现场试验和室内试验的数据可以相互对照、比较以确定有效性和了解基本的溃决形成过程)与数字模型试验联系起来进行比较和分析。另外,还考察了影响溃坝地址的各种因素,也对与溃坝模型相关的不确定性进行了考察。 The WP2 project IMPACT is focused on improving the ability to predict the formation of crashes by studying dams or watertight dikes. Its core task is to compare and analyze the field tests and laboratory tests (the data of field tests and laboratory tests can be compared with each other to determine the validity and understand the basic process of the formation of the failure) with the numerical model tests. In addition, various factors that affect the address of dam break are also examined, as well as the uncertainty associated with the dam break model.
