Breaching Processes: A state of the art review

This report provides an overview of the state of the art with regards to embankment breach initiation and formation processes. Basic breach formation processes are explained, including a review of commonly held misconceptions. The different stages of breach initiation and formation are also explained, along with the varying needs of different...

Review of the IMPACT Project breach field test data

The IMPACT Project (www.impact-project.net) provided valuable data on breach formation processes. Five large scale field tests were performed in Norway, and a further 22 laboratory tests were performed in the UK. A review of this data has been undertaken to support breach model testing and development under Task 6.

Hydraulic model tests on breaching with and without waves

This report describes small-scaled experiments performed at Leichtweiß-Institute for Hydraulic Engineering and Water Resources, Technical University Braunschweig (LWI). The experiments have been conducted to investigate the development of dike breaches in homogeneous sand dikes with and without a clay layer. The used scaling factor was 1:10.The...
