Cartography and GIS
The purpose of the paper is to clarify the formation mechanism of the devastating flood in the town of Svilengrad, in the Republic of Bulgaria, in June 2012.
The systemic approach is used to analyze flood formation mechanisms and improve under-standing of the complex interactions between the factors determining the formation and manifestation of floods. The spatial analysis method takes a central place in the examination of the flood formation mechanisms, using GIS as a tool for analysis. Hydraulic model for the 9 km long river section has been adapted and for this purpose a Digital Elevation Model (DEM) has been generated. Taking into account the specifics of the riverbed and the results of previous research on the design and investment process in the river area, a one-dimensional model is applied (Hydrologic Engineering Center - River Analysis System, version 5.0.3, developed by the US Corps of Military Engineers) to determine the flooded areas during the flood.
The main result of the study is the clarified flood formation mechanism in the town of Svilengrad, which occurred on 06.02.2012.
Information on the flood formation mechanism is of particular importance for the institutions responsible for flood risk assessment and management. It will allow them to formulate adequate measures for reduction of the floods risk in this part of the Maritsa River. The popularization of the results of the survey among the population of Svilengrad is a prerequisite for raising its awareness and preparedness for a more adequate response in case of a new disaster/flood.
