The WRCS Hydrology Software Suite
WRCS has collected over a dozen software programs that represent a wide cross-section of hydrologic modeling utilities developed for various applications in water resources engineering. These programs, and their User's Manuals and supplemental documentation files have been re-formatted on to one CD for easier installation and your convenience. Many of the programs have documentation in Adobe PDF format, which can be viewed with the Adobe Acrobat Reader, also included on the CD.
Here is a list of the software packages on the CD, as well as a brief description of each. Click on any program title in the following list to go to the description of that program:
ANNIE / HEC DSS / HSPF / HYDRAIN / HYSEP / PeakFQ / SITES / SMADA / SWMM44 / SWSTAT / TR-20 / TR-55
ANNIE |
ANNIE is a program designed to help users interactively store, retrieve, list, plot, check, and update spatial, parametric, and time-series data for hydrologic models and analyses. Data are stored in a direct access file called a Watershed Data Management (WDM) file. Many hydrologic and water-quality models and analyses developed by the U.S. Geological Survey (USGS) and the Environmental Protection Agency (EPA) currently use WDM files. |
HEC DSS |
The HEC Data Storage System (HEC-DSS or just DSS) stores data in a fashion convenient for inventory, retrieval, archiving and model use. The DSS was
primarily designed for water resource applications. The DSS can be interactively used with the following Corps of Engineers programs or program input and output data files: FFA, HEC-1, HEC-5, HEC-HMS, HEC-RAS, UNET. The user may interact with the data base through: a) Utilities that allow entry, editing, and display of information, b) Application programs that read from and write to the data base, c) Library routines that can be incorporated in any program to access data base information. The DSS provides a means for: 1) storing and maintaining data in a centralized location, 2) providing input to and storing output from application programs, 3) transferring data between application programs and, 4) displaying the data in graphs or tables. |
HSPF |
HSPF- Hydrological Simulation Program--Fortran simulates for extended periods of time the hydrologic, and associated water quality, processes on pervious and impervious land surfaces and in streams and well-mixed impoundments. HSPF uses continuous rainfall and other meteorologic records to compute streamflow hydrographs and pollutographs. HSPF simulates interception soil moisture, surface runoff, interflow, base flow, snowpack depth and water content, snowmelt, evapotranspiration, ground-water recharge, dissolved oxygen, biochemical oxygen demand (BOD), temperature, pesticides, conservatives, fecal coliforms, sediment detachment and transport, sediment routing by particle size, channel routing, reservoir routing, constituent routing, pH, ammonia, nitrite-nitrate, organic nitrogen, orthophosphate, organic phosphorus, phytoplankton, and zooplankton. |
HYDRAIN |
HYDRAIN 6.1 (1999) Integrated Drainage Design Computer System HYDRAIN contains the following programs: HYDRO, HYDRA, WSPRO, HY8, and HYCHL All the programs included with this release of HYDRAIN can perform calculations and present results using either U.S. customary units (English) or SI units (metric). HYDRO generates rainfall estimates, peak runoff estimates, and/or hydrographs. HYDRA is a pipe network hydraulics program used to model an existing storm drain/sewer system or to design a new system. WSPRO is a step backwater program for natural channels with an orientation to bridge constrictions. HY8 is a program that presents HDS-5 procedures for analysis and design of highway culverts, design of energy dissipators, storm hydrograph generation, and reservoir routing upstream of a culvert. HYCHL is a program which assists in the analysis and design of roadside channels and riprap lining. |
HYSEP |
HYSEP - Hydrograph separation program performs hydrograph separation, estimating the ground-water, or base flow, component of streamflow. The program provides an automated and consistent method for estimating base flow. Any of the three hydrograph-separation techniques of Pettyjohn and Henning (1979) can be used: fixed interval, sliding interval, or local minimum. |
PeakFQ |
PEAKFQ - Flood-frequency analysis based on Bulletin 17B performs flood-frequency analysis based on the guidelines delineated in Bulletin 17B, published by the Interagency Advisory Committee on Water Data in 1982. The program is interactive and contains the code from the WATSTORE program J407. |
SITES |
SITES - The SITES software is a descendent of the DAMS2 program. DAMS2 was a full-featured rainfall-runoff routing program developed for watershed dam design and analysis. In developing the SITES software, DAMS2 was recoded and the auxiliary (emergency) spillway analysis portion of the program was rewritten and expanded to include new technology for spillway performance evaluation. |
SMADA |
SMADA - Stormwater Management and Design Aid - This software is a complete hydrology package included as a number of separate executable files. These programs work together to allow hydrograph generation, pond routing, storm sewer design, statistical distribution and regression analysis, pollutant loading modeling, matrix calculation, and others. These programs are useful in both classroom and professional applications. Extensive on-line documentation is available for all programs. |
SWMM44 |
SWMM version 4.4 - This Rainfall Runoff Model was developed by the US Environmental Protection Agency, Oregon State University and Camp, Dresser & McKee, Inc. It is a large, complex model capable of modeling the movement of precipitation and pollutants from the ground surface through pipe and channel networks, storage treatment units, and finally to receiving waters. Both single event and continuous simulation can be performed on catchments having storm sewers and natural drainage, for prediction of flows, stages and pollutant concentrations. |
SWSTAT |
SWSTAT, Surface-Water STATistics - contains a number of options for statistically analyzing time-series data. The time-series data are read from a Watershed Data Management (WDM) file. The computed statistics and (or) time series can be written back to the WDM file or to a text file. The statistics options include: Basic, Compare, Duration, Frquency, Hydrograph, N-Day and Trend. |
TR-20 |
TR-20, Technical Release No. 20: Computer Program for Project Formulation Hydrology (TR-20) is a physically based watershed scale runoff event model. It computes direct runoff and develops hydrographs resulting from any synthetic or natural rainstorm. Developed hydrographs are routed through stream and valley reaches as well as through reservoirs. Hydrographs are combined from tributaries with those on the main stream stem. Branching flow (diversions), and baseflow can also be accommodated. |
TR-55 |
TR-55, Urban Hydrology for Small Watersheds - Technical Release 55 (TR-55) presents simplified procedures to calculate storm runoff volume, peak rate of discharge, hydrographs, and storage volumes requ |
