HEC-1 Flood Hydrograph Package. Users Manual
Abstract
HEC-1 is a mathematical watershed model designed to simulate the surface runoff response of a river basin to precipitation by representing the basin as an interconnected system of hydrologic and hydraulic components. Each component models an aspect of the precipitation-runoff process within a portion of the basin. A component may represent a surface runoff entity, a stream channel or a reservoir, defined by parameters specifying its characteristics and the mathematical relations describing the physical processes. The result of the modeling process is computation of streamflow hydrographs at desired locations in the river basin. All ordinary flood hydrograph computations associated with a single recorded or hypothetical storm can be accomplished with this package. Software Description: The program is written in FORTRAN 77 for implementation on IBM PC/XT compatible equipment, using MS/PC DOS 2.1+ operating system. Minimum of 640 K bytes core. Two 5 1/4 floppy disk drives, or one 5 1/4 floppy disk drive/and a 10 MB hard disk Math coprocessor (8087, 80287,80387) highly recommended but not required. hard disk is required to run MENU1.
