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...

The objective of the study is to calculate with highest reliability the values of the maximum runoff with different probabilities in Nishava catchment, in relation to elaboration of flood risk maps for Godech town. To calculate the maximum runoff of the Nishava catchment, the regionalization method was applied. This method was developed in the state of Baden-Wurttemberg, Germany and is widely used in practice. It is based on eight characteristics and factors of catchment areas and river systems: catchment area; ur...

The purpose of this publication is to assess the multi - risk of hydro meteorological hazards (drought, hail, snowfall and snow accumulation, fog, floods, winds, fires) on the territory of the Danube Water Management District (DWMD). DWMD is one of the four districts designated for water management on the territory of the Republic of Bulgaria. For this purpose, an approach for multi-risk assessment has been developed, which is part of the overall risk management process. It includes three stages: risk identificati...

Air pollution is one of the main environmental causes for the occurrence of many diseases in the Republic of Bulgaria. Despite the efforts and measures taken by the responsible institutions, polluted air continues to have adverse effects. Bulgaria is still far from achieving levels of air quality that do not pose a risk to humans and the environment. In this context, the purpose of this publication is to evaluate the air quality of the border municipalities between the Republic of Bulgaria and the Republic of Serb...

Monitoring progress in the water sector requires an interdisciplinary approach and involves quantitative and qualitative assessment. This need must be integrated in such a way as to allow the solution of a wide range of tasks. In addition, the process should allow the inclusion of views and evaluations of water users. To evaluate the progress of a municipality, country or region, it is necessary to build a monitoring system based on simplified indicators. In this context, the purpose of this publication is to adap...
