The HFAM systems consist of a set of physically-based, continuous, deterministic models. Modeling results are viewed in graphical displays. A variety of screens show the model setup and maps of the watershed area. HFAM combines hydrologic simulation and data management with an interactive graphical interface to provide a tool for streamflow forecasting and log-term analysis of streamflow, reservoir operations, and watershed development. HFAM (Hydrocomp Forecast and Analysis Modeling) A graphical user interface allows the user seamless movement between the different parts of the program. The program features a completely integrated work environment including a database, data entry utilities, computation engine and results reporting tools. It is designed to be applicable in a wide range of geographic areas for solving the widest possible range of problems. The HEC-HMS is designed to simulate the rainfall-runoff process of dendritic watershed systems. This US Army Corps of Engineers program performs frequency computations of annual maximum flood peaks in accordance with the Water Resources Council "Guidelines for Determining Flood Flow Frequency" Bulletin 17B The output is a HEC-1 input ready table of incremental rainfall depths. It will distribute rainfall over SCS Type I, II, or III storm patterns or a user specified pattern. This program will take a cumulative rainfall total and distribute it incrementally over a set storm time period. HEC-HMS will eventually replace this program. The program will allow various methods for calculating rainfall hyetographs, basin unit hydrographs and watershed loss rates. This program will produce runoff hydrographs for complex watershed networks using unit hydrograph or kinematic wave methods and incorporating reservoir and channel routing procedures. US Army Corps of Engineers Flood Hydrograph Package for rainfall-runoff simulations. The program provides the calculation of unbiased frequency factors and confidence limits for estimates. User Friendly Data Input.įREQ is least squares estimation program for LP3 flood frequency estimation. Built-in Volume Calculations, Automatic Soil "C" adjustment using Burn Factor if desired. The program is fully MS-Windows 3.1 and MS-Windows 95 based with menus and push buttons for easy user-program interface Gumbel, Log Pearson Type 3, 2 or 3-Parameter Log Normal distributions are available. Alternatively the user can enter low flows manually.

This program is a preprocessor for generating 7-day or 30-day average flow series from daily flows available from standard data bases such as HYDAT or USGS. The program is fully MS-Windows 3.1 and MS-Windows 95 based with menus and push buttons for easy user-program interfaceĮSLOFFAN (Engsoft Low Flow Frequency Analysis) Gumbel, Log Pearson Type 3, or 3-Parameter Log Normal Distribution are available (more distributions available optionally). Alternatively flood flows can be entered manually. This program is a preprocessor for generating 1 to 12 annual flood flow series from daily flows available from standard data bases such as HYDAT or USGS. The method uses Snyder's Least Squares algorithm coupled with the author's modified smoothing method.ĮSFFAN (Engsoft Flood Frequency Analysis) Provides an estimation of a unit graph from rainfall and discharge data.

There is also an expanding library of subroutines for graphics, user interaction, and data storage and retrieval available to application programmers designing software utilizing WDM files. The WDM file provides users with a common data base for many applications, thus eliminating the need to reformat data from one application to another. Geological Survey ( USGS) and the Environmental Protection Agency ( EPA) currently use WDM files. Many hydrologic and water-quality models and analyses developed by the U.S. Data are stored in a direct access file called a Watershed Data Management ( WDM) file.
