Welcome to the WRCS Hydrology & Hydraulics Software Shop,
the premiere spot for locating hydrology and hydraulics modeling tools.

WRCS is an authorized vendor of both US Army Corps of Engineers and commercial surface water hydrology and hydraulics (H&H) computer programs.  We also feature many free software downloads. For information on our firm and the engineering services that we provide, please go to our WRCS Profile Page.

Current News Notes: Check out our What's New! page for details and the latest in H&H modeling news.

Here is a sampling of the programs we are now featuring:

Our Featured Program Packages:

• WRCS Hydrology & Hydraulics Software Suite:
  WRCS has collected over two dozen software programs that represent a wide cross-section of  hydrologic and hydraulic modeling utilities, developed for various applications in water resources engineering, all on one CD.
• HEC-Works CD:
  HEC-RAS (River Analysis System), HEC-HMS (Hydrograph Management System), HEC-SSP (Statistical Software Package),  HEC-1 (Flood Hydrograph Package), HEC-2 (Water Surface Profiles), HEC-5 (Reservoir Regulation System), HEC-6 (Scour and Sedimentation) and the HEC-DSS (Data Storage System) Utilities, all on one CD!
• Aquadyn Hydrodynamic Modeling System:
  AquaDyn is a powerful and easy-to-use hydrodynamic simulation software package for water resources engineering studies, risk assessment, and impact studies. It allows the complete description and analysis of two-dimensional hydrodynamic conditions (e.g., flow rates, water levels, concentration of diffused particles or heat) of open channels such as rivers, lakes, and estuaries.
• Hydroflo for Windows:
   A tool for the design and analysis of fluid conveyance systems that consist of a single source and a single discharge and up to 10 parallel lines. Up to 10 pumps in series or parallel may be modeled. HYDROFLO 2 allows a designer to "drag and drop" pipes, pumps, fittings and valves into a design.
• Hydronet 4:
  A powerful DOS based application that solves for the steady-state pressures and flows throughout a fluid conveyance network. Systems of up to 3,000 pipes, 1,000 fittings and valves, 300 pumps and 3,000 nodes can be analyzed. Easy data entry, fast solutions and 3-D system graphics make this software essential for all hydraulic design professionals.
• PumpBase:
  Finds the best pumps for your fluid conveyance application using 40 criteria from 1000's of curves. PumpBase provides graphic output of pump performance, system and NPSHR curves. Selected pumps are ranked by efficiency and are displayed with associated data.
• RipRap:
  The RIPRAP Design System is a powerful stream bank protection design software. The RIPRAP Design System determines sizing, layer thickness and gradation of rock riprap to protect streams from scour utilizing seven different methods. Simple single execution allows the user to quickly compare results.

Latest Corps of Engineers Releases:

• HEC-SSP:
  The U.S. Army Corps of Engineers Statistical Software Package (HEC-SSP). This software allows you to perform flood flow frequency analyses of hydrologic data. HEC-SSP is available as part of WRCS's HEC-Stats Pack CD.
• HEC-RAS Version 4.0.0:
  The latest version of the Corps' River Analysis System water surface profiles modeling software. HEC-GeoRAS is available as a FREE Add-On to HEC-RAS.
• HEC-HMS Version 3.1.0:
  The latest version of the Corps' Hydrologic Modeling System. HEC-GeoHMS is available as a FREE Add-On to HEC-HMS.
• HEC-ResSim Version 3.0:
  HEC-ResSim performs Reservoir System Simulations to meet the needs of real-time reservoir regulators for a decision support tool, as well as the needs of modelers doing reservoir projects studies.
• HEC-DSSVue 1.2.10
  HEC-DSSVue is a graphical user interface program for viewing, editing, and manipulating data in HEC-DSS database files.

New Free Programs For Download:

• NSS - The National Streamflow Statistics Program:
  An easy to use computer program for estimating streamflow statistics for ungaged sites for a variety of water-resources and emergency planning, management, and regulatory purposes, and for design of structures such as bridges and culverts.
• HCALC for Windows:
  A  full pipe flow calculator/unit converter program for Windows. You can solve for head loss, diameter or flow using the Darcy-Weisbach, Hazen-Williams or Manning equation.
• Inlet on Grade:
  An Excel application which calculates the flow capacity of street sections and catch basins on continuous grade.
• LoggerDB:
  LoggerDB is a database program specifically created to store time-series data. Its great for stream gage stations because it has separate tables for rating curve entry, journals and offsets.
• Time Series Manager:
   A software tool providing convenient access to HEC-DSS databases. 

And numerous other FREE download programs, including: CEPIPE, DCUH, DESERT,  FREQ, H&H Utility Suite, Hydraulics Utility Programs, HEC-1Time, Surface Profile Calculator for Windows....and MORE. Go to our FREE PROGRAMS page for all of these downloads.
