ABSTRACT: This article introduce the hydrogeomorphological GIS based method of floodplain delineation based on elevation data and flood heights increasing downstream. The results were compared with floodplains derived from soil maps and with boundary mapped using GPS points. The advantage of this method is the low demands on the input data and the ability to define the floodplain of a large catchment area. Resulting floodplain maps present possible flooded area and can be used in preliminary flood risk assessment and landscape planning.
