The paper studies the impact of the flooding water on environment – water bodies, soil and other endangered values. The proposal of flood environmental impact and risk assessment index calculation includes state of environment and environmental hazards in the chosen area. Keywords: Environmental impact assessment, risk analysis, Bodva river basin, Slovakia, flood risk, sources of pollution 1 INTRODUCTION Year 2010 was in terms of precipitation extremely above average and with significantly unequal in distribution of rainfall in each month in all regions of Slovakia. These rainfall conditions had a significant impact on the environment, catchment saturation and hence the overall flood situation on extreme flows in Slovakia, also a significant increase in groundwater levels, which flooded buildings.
