Abstract: Research under work package 2 (WP2) of the IMPACT project focuses on our ability to predict breach formation through a dam or flood defence embankment. The core work links field and laboratory testing (to collate reliable data sets and understand basic breach formation processes) with numerical model testing, comparison and development. In addition, consideration is given to factors affecting breach location and also the uncertainty associated with breach modelling is also investigated.

摘要： 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。
