Flash floods and landslides pose a serious problem for Odessa region of Ukraine, especially for its coastal line. They have an impact on environment, social and industrial infrastructure, cause loss of recreational areas, unique landscapes and agricultural lands.

Flash floods and landslides risk assessment is an important tool for coastal zone management and natural hazards prevention in the North-Western part of the Black Sea [1]. This is an important part of integrated approach to disaster mitigation, which takes into account four stages of the natural hazard mitigation cycle – prevention, preparedness, response and recovery [2-5].

The paper aims to locate and assess the potential areas that can be influenced by flash floods and landslides. As the pilot areas for the flash floods risk assessment were chosen the basin of the Ukrainian part of the Danube delta (regional scale) and basin of Aliyaga river (local scale).

Landslide hazard assessment on the regional scale was made for Odessa region using the Mora & Vahrson methodology. Maps were created using the software QGIS 2.10, SAGA GIS 2.1 with partial use of ArcGIS 10.2.

This research was supported by the Join Operation Programme “BLACK SEA BASIN 2007-2013” (Project “A Scientific Network for Earthquake, Landslide and Flood Hazard Prevention – SciNetNazPrev”). Approaches of risk assessment were harmonized with the practices of neighbouring EU countries.
