Integration of satellite monitoring for flood risks forecasting on the example of the Dnister’s Flood Surveying Site

The relevance of the study lies in the development, improvement and practical implementation of a geoinformation approach to flood risk forecasting within the Dniester flood control area by integrating satellite monitoring, spatial analysis and interpolation methods. The study was aimed at creating an effective system for identifying potentially dangerous areas, analysing floodwater pollution and assessing the impact of climate change on hydrometeorological processes in order to increase environmental safety and ensure sustainable risk management at the level of territorial communities. Mapping of Quaternary deposits, geomorphological levels and landscape structure was carried out, and a forecast map of flooding of territories with water rising by 1, 3, 5 and 10-12 meters was constructed. The final result was a 3D map, which is presented as an interpolated surface, created using the inverse weighted distance method. The optimal intervals of the value and size of the cells were selected: the obtained result allows not only to analyse the risks of flooding, but also to draw up reports with visualisation of data stored in the form of graphic images. For the first time, a map of the ecological risk of flooding of the Dniester flood control site by catastrophic floods was created for the Dniester Valley and adjacent territories of Podillia and Prykarpattia. The study showed that the process of flooding of the Dniester Valley occurs sequentially: first, the low floodplain is flooded (water rise +1 m), then the middle (+3 m), high (+5 m) floodplains and, finally, the first suprafloodplain terrace (+10-12 m). Based on the identified patterns, a system for predicting the rise of water during floods was developed. In addition to forecasting, this system performs the function of notifying the population about catastrophic manifestations of water elements
