Flood environmental impact risk analysis

Abstract

The aim of this paper is to determine the degree of threat in the floodplain of the Hornád river basin and to propose measures that can be used in practice at the time of the flood. The methodology is based on the principle of FEIRA (Flood Environmental Impact Risk Analysis), where the probability and consequence of the negative impact of floods on environmental components is determined on the basis of the analysis of selected stressors. From these indicators, the degree of risk in the Hornád river basin in the event of a flood is subsequently determined. Since there are several industrial sites in the solved area, which can cause extensive pollution of watercourses in case of floods, the work also presents the calculation of the threat according to the point evaluation of pollution sources. The combination of the FEIRA process and the proposed methodology for the assessment of flood environmental damage determined the overall risk of environmental damage due to floods in the Hornád catchment area. This paper is a proposal for measures to protect against floods in the area in case of floods.
