Abstract
Hydrological components that important in solving the hydrological problems in a watershed is streamflow. However, streamflow measurement data is still very lacking. To overcome these problems, the streamflow can be estimated through the analysis of the water balance using a variety of hydrological models. One streamflow prediction model is Watershed Modeling System (WMS). WMS is a graphical modeling software for all phases of a watershed hydrology. This research aims to simulate the streamflow by using a technical model of watershed modeling system releases 55 (TR 55) in the sub watershed Saddang, Sulawesi. Peak discharge obtained from the simulation results over a period of 2, 5, 10 years, respectively 59.45 m3/second, 74.60 m3/second and 84.80 m3/second. The analysis of regression between measurements and simulated discharge shows a strong correlation with the value of determination of 0.78.
