Abstract/Additional Information |
During extreme flooding and internal erosion failure events, detailed data on flow and formation processes of breaches through embankments / dams are rarely recorded. Consequently field and laboratory tests of embankment breaches due to overtopping and piping have been conducted to support numerical model development, testing, and verification. Controlled field tests of rock fill, clay, and glacial moraine embankments, 5-6 m height, have been conducted in Northern Norway. Laboratory tests of sand, and clay embankments, 0.6 m height, have been conducted in a large flume at HR Wallingford, United Kingdom. Observations and conclusions from these tests will be presented in this paper. 16 pp., 1 table, 22 figures, 5 references.
