Abstract: The Corps of Engineers' HEC-1 program has been used with a specialized pre-processor program to provide interim emergency flood forecasting for a 4000 sq mi (10,360 sq km) watershed in east-central Missouri. Results to date have been excellent despite inadequate real-time data, particularly rainfall information. Flood crests have been predicted within 1-2 ft (0. 3-0. 6 m) with 24-48 hr warning time on all but one occasion.
