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).

Last year the Hydrologic Engineering Center (HEC) and the Waterways Experiment Station incorporated the results from more than ten years of research and development into a new version of computer program HEC-6: 'Scour and Deposition in Rivers and Reservoirs' (HEC, 1977). Because of the extensive modifications made to HEC-6, an entirely new User's Manual was also prepared. HEC released a Beta Test Version of the program in the fall of 1989, for field testing. Public release of the new version of HEC-6 is scheduled for September 1990. This paper describes the present status of the program as of April 1990, the expanded capabilities, and the improved documentation to be included in the forthcoming release of computer program HEC-6. Keywords: Computer programs; User manuals; Sediment transport modeling; Deposition; One-dimensional mobile boundary model; Rivers; Reservoirs. (CP).

This technical paper presents a general overview of the Corps of Engineers' past involvements, present practices, and the future roles in dealing with alluvial fan flooding problems. The Corps' approach to alluvial fan flooding studies and the analytical methods they use to assess potential flood hazards are summarized. Selected case studies are presented. Six important issues that need to be considered as part of an effective alluvial fan management approach are presented. An extensive list of references is also included. (fr).
