The Hydrologic Engineering Center(HEC) implemented HEC-2 for MS-DOS compatible microcomputers (PC) in 1984. The edit program for HEC-2 data (EDIT2) was also implemented at that time. The PC program distribution started in the fall of that year. The programs were modified to meet Fortran 77 standards. The PC versions maintained all the capabilities of the original mainframe version of the programs, except for internal trace and comment information. For the past two years, HEC program development has focussed on providing a more convenient set of programs for PC use. The package for programs described here reflects our attempt to bring together all the necessary tools to accomplish a complete computation and display of water surface profiles on a personal computer. Refinements to the programs, to take advantage of the unique capabilities of the PC, will continue as funds are available. Contents: Overview of the HEC-2 Package; Program Support; Computer Equipment Requirements; New Input/Output Programs; and Current Program Developments.

Flood control and flood plain management investigations using spatial data management techniques are increasing in the Corps of Engineers. Pilot studies initiated in the mid-1970's were successful in consolidating analysis concepts, fostering the development of spatial data file creation and management technology and enhancing the consideration of existing and alternative future development patterns in Corps' planning studies. Over 30 studies using HEC-SAM, the Corps' spatial data management system, are now completed or underway. HEC-SAM was created through selective acquisition of commercial software, adaption of academic research products, and development by researchers at the Corps' Hydrologic Engineering Center (HEC). The HEC role continues to be that of system developer and technology transfer agent. The evolution, present capabilities, and applications of HEC-SAM are described. Observations are offered on spatial technology development, implementation, and servicing. (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 paper describes the new version of the HEC-1 Flood Hydrograph Package - a comprehensive simulation model computer program. The many hydrologic and hydraulic simulation capabilities of the model are described. Special emphasis is given to analysis of dam safety and dam failure flood damage studies, and urban hydrology. The general applicability and usage of the model are described. (Author).

The Corps' Hydrologic Engineering Center (HEC) has developed a generalized simulation model capable of analyzing complex river-reservoir systems. The development of the model, 'HEC-5, Simulation of Flood Control and Conservation Systems' (Eichert, 1974, 1975) has been paced by the changing mission of the Corps as well as the evolution of computer systems. HEC-5 development and management, including code development, testing, documentation, training and field application experience, is discussed. (fr).
