#DniproHesFlood
🛰️ Dam-break modelling with GRASS GIS

I used the r.damflood module in GRASS GIS on a historical scenario:
the destruction of the DniproHES dam by Soviet forces in August 1941 during their retreat from Ukraine.

I reconstructed a pre-war DEM of the Dnipro River from old topographic maps, modeled the dam structure, and created a breach raster.

Using r.damflood, I simulated the propagation of the flood wave over the first 24 hours after the dam explosion.
Based on this model, I generated a visualization showing the wave dynamics.

All tools used are fully open-source.
The results have not yet been published anywhere.

Geospatial analysis and modeling is not only about:
1. downloading Copernicus data,
2. generating pretty maps,
3. calling it “analysis”.

In reality it often means years of collecting and reconciling heterogeneous data from different eras: digitizing historical maps, fixing coordinate systems, validating geometry through indirect evidence. This stage can easily take more time than all later modeling.

The images show how I digitized and georeferenced 1920s–1940s topographic maps of the lower Dnipro region. After transforming them into a unified coordinate system, I used them to reconstruct the pre-flood terrain (before the Kakhovka Reservoir).
That DEM later became the basis for modeling the 1941 DniproHES dam-break wave.

…This data-preparation phase alone took me almost four years.

The CEO of "Ukrhydroenergo" reported significant damage to DniproHES due to the recent attacks. He emphasized that the upper part of the building will need complete restoration, while the analysis of the equipment is pending. Over 8 rockets hit the facility, causing extensive damage. It will take at least 2-3 days to assess the full extent of the damage. The CEO stressed the need for restoration, and the assessment of the consequences will depend on the time and cost. #Ukraine #DniproHES

In Zaporizhia near the DniproHES, there were 2 direct hits - at HES-1 and HES-2, with the latter being seriously damaged. The full restoration of the machinery room and electrical equipment will be required. The consequences will be assessed within a day to understand the situation and the operational capacity of HES-2. #Zaporizhia #DniproHES
