Flood simulation was conducted in the Gills Creek (hydrologic unit code (HUC): 0305011002; 193 [km.sup.2]) watershed in central South Carolina and Waccamaw (HUC: 03040206; 4277 [km.sup.2]) watershed at the border of South Carolina and North Carolina (Figures 1 and 2) using HEC-HMS [30].
Although the PRISM data provide areal representation of precipitation for a longer time period than radar data (i.e., 1981 to present), the daily temporal resolution of the PRISM data is not adequate for HEC-HMS which requires hourly precipitation inputs.
In the HEC-HMS model there are six main folders: basin (where the conversion of the rainfall/runoff is carried out through the hydrological elements of the model), meteorologic (that defines the meteorologic boundary conditions of the model), control specifications (that describes start and end time of the simulations), time-series data (where the time-series of precipitation data is inserted in the model), paired data (functional data such as cross-section profiles, unit hydrographs and storage-discharge data, depending on the available data that the modeller has for the study) and grid data (for the management of the model grid cells).
Shabanloo and Hamrang [14] showed in a study of flood hydrograph estimated by the models of integration and distribution in the catchment basin By HEC-HMS and HEC-GeoHMS programs, it is closer to the formation of surface flow hydrograph and precipitation formation in a modified distribution method ModClarc integrated approach towards the SCS hydrograph recorded in the basin.

These models have recently evolved towards HEC-HMS and HEC-RAS, which should be used in the near future.
Section 3 provides a description of the HEC-HMS hydrological model, followed by a detailed discussion of the calibration procedures and simulation scenarios for the hydrologic model and then lists statistical criteria of its performance evaluation.
