The computer program HEC1F, developed by the Corps of Engineers' Hydrologic Engineering Center, performs runoff forecasting. The focus of this paper is on application of HEC1F in making short-term (three to five day) forecasts for the 11,733 square mi. Allegheny River Basin, which contains nine flood control reservoirs operated by the Pittsburgh District, Corps of Engineers. Following a brief overview of the nature and scope of the water control software system, the intended application of HEC1F is provided. The characteristics of the Allegheny Basin, data collection networks, and forecast needs are described, as well as the approach used for model calibration and initial results. Finally, comments are made regarding the present status of model development and usage, and plans for the future.
