The document discusses the creation of a geographic database for the upper Nishava catchment area. A GIS platform was established including ArcGIS software. The database includes spatial data on boundaries, rivers, infrastructure, climate, land use, and more. Layers were created from various sources and formats. Maps were produced showing potential population, environmental, and transportation risks from flooding in the catchment area, including specific maps for the towns of Godech and Dimitrovgrad.
