Model of a 200 - 1800 m dam break at the Nova Kakhovka dam

Modeled by Dämmningsverket AB using the US Army Corps of Engineers (SACE) software HEC-RAS 6.3. The terrain data comes from Nasa.’s Shuttle Radar Topography Mission (SRTM) and are available from the United States Geographical Survey (USGS). The model is not based on actual measurements of the current state of the Dnipro flow, waterline, temperature, humidity, air pressure, wind speed and anytning else which would affect the model, but on assumptions for a worst case. Assumptions include that the water-level in the dam is 13 meters above the Dnipro downstream, and that the dam break over an hour expands to a width of approximately 200, 400 and 1800 meters. The destruction of the dam by Russia woudl be a war crime according to the Geneva Convention.
