In this study, flood simulation analysis was carried out for the natural channels in the urban area and a risk map of flood waters was formed. For this purpose, Horata channel in Malatya city center was selected as the application area where there are a total of four streams, which have the flood risk potential. The flood events observed in the past were investigated and the factors that cause it were evaluated. Flood hydrographs were obtained for 50, 100 and 500 year return periods for the Horata channel. Info-works ICM was used for flood simulation and flood analysis was performed for different recurrence periods. It was observed that stream sections were inadequate and settlement areas would be adversely affected especially for the return period of 500 years. As a result, flood propagation maps were created for each case and the affected areas were determined. According to the results of these analyzes, the regions where the risk of floods are high can be listed as follows, especially where the natural flow is disturbed, the section is constricted for bridging, the areas where meandering are formed, regions where the section is insufficient.
