HEC-1 (Hydrologic Engineering Center-1) and HEC-2 (Hydrologic Engineering Center -2) Applications on the Microcomputer

摘要

The hydrologic Engineering Center (HEC) has developed versions of the HEC-1 Flood Hydrograph Package and the HEC-2 Water Surface Profiles Programs for MS/PC-DOS compatible microcomputers (PC). The increased speed, memory and storage capacity of the latest PCs make the use of these large FORTRAN programs highly practical in the PC environment. Typical tasks that are required when using these batch oriented programs include creating, checking and editing input data; executing the program; and summarizing and displaying the results. The HEC has developed a menu driven user interface or shell program to integrate several application programs, an editor and other utility programs to assist the user in accomplishing these tasks. The interface takes advantage of the unique capabilities and user friendliness found in the PC environment. In addition to the HEC-1 and HEC-2 programs, the integrated package includes a program (SUMPO) for creating summary tables of HEC-2 results, a program (PLOT2) that plots cross sections and water surface profiles, and a PC version of the Corps of Engineers editor (COED), which features full screen editing and on-line help screens and documentation. The application of these programs is described and demonstrated using the menu driven interface. (Author)
