The volcanic Burda Mountain is located in southwest Slovakia, surrounded by the Danube, Hron and Ipeľ rivers. Their conflence creates signifiant flod-risk potential leading to arable land damage and consequent soil erosion in the inundation area. This article presents the mapped range of flod-affected areas during the June 2013 flod event; especially noting the paralyzing effct on Chľaba village on the Slovak–Hungarian border. Our map of the sloped and underfloded areas is based on conventional fild research methods and is compared with the prognostic Flood Hazard Map and Flood Risk Map created in the Danube FloodRisk project. We also propose landscape use changes to reduce negative flod impact, and intend this case study to encourage realistic government department awareness which will help marginal Slovak areas regularly enduring debilitating flod damage.
