Flood discharges can be calculated by using the flow observation station data and the precipitation observation station data. In this study, both of the data set were evaluated and the results were correlated each other. Firstly (Model 1), based on flow data of Kocaırmak (Bartın) River, the possible flood discharges were calculated by using different statistical distribution functions. Secondly (Model 2), calculations were made with the help of different maps and different methods based on the data of precipitation observation stations using software. In Model 1, as a result of calculations made with Normal, Log Normal, Gumbel and Pearson distributions functions, the flood discharges according to 50 year return period were determined as 926, 1579, 1128, and 1024 m3/sec, respectively. The calculations made with the help of DSI and Mockus methods using the 1/25000 scaled digitized topographic maps and Aster-GDEM images with 30x30 m resolution in Model 2, the flood discharges were calculated as 999, 1305, and 1033, 1332 m3/sec, respectively. By comparing the results obtained from models, it was found that the values obtained by Pearson distribution from Model 1 and the values obtained by DSI Synthetic Method from Model 2 were correlated well with each other.
