NSS: The National Streamflow Statistics Program

Floodflow Frequency Plots and Hydrographs for Ungaged Watersheds

  
Estimates of streamflow statistics are used for a variety of water-resources and emergency planning, management, and regulatory purposes, and for design of structures such as bridges and culverts. These estimates are often needed at ungaged sites where no observed flood data are available.

To provide simple methods of estimating streamflow statistics, the U.S. Geological Survey (USGS) has developed and published regression equations estimating the magnitude and frequency of floods for every State, the Commonwealth of Puerto Rico, and a number of metropolitan areas in the United States, and regression equations for estimating other streamflow statistics are available for many states. These equations have been compiled into the National Streamflow Statistics (NSS) Program.

NSS is a Visual Basic program that can be used to:

1. Obtain estimates of various streamflow statistics for sites in rural ungaged basins.
2. Obtain estimates of flood frequencies for sites in urbanized basins.
3. Obtain indicators of the errors associated with the estimated streamflow statistics.
4. Obtain estimates for ungaged sites by use of the Region-of-Influence method.
5. Estimate maximum floods based on envelope curves developed by Crippen and Bue (1977).
6. Create hydrographs of estimated floods for sites in rural or urban basins.
7. Create flood-frequency curves for sites in rural or urban basins.
8. Obtain improved flood-frequency estimates for gaging stations by weighting systematic flood record estimates with estimates from regression equations.
9. Obtain improved flood-frequency estimates for ungaged sites by weighting regression equation estimates with estimates obtained from upstream or downstream gaging stations.
10. Save output from the program in text and graphic files.
11. Obtain documentation and instruction for use of the program from help files.

The NSS Program is available for FREE by download from the Free Software page of the WRCS H&H Software Shop web site.

 

The WRCS H & H Software Suite

24+ Hydrology and Hydraulics Software
 Program Packages on One CD

Over two dozen hydrologic and hydraulic software program packages, developed for various applications in water resources engineering, have been compiled on this single CD. All of these programs, along with all of their documentation files, are included in the WRCS H&H Software Suite:

HYDROLOGY:

  • 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.

  • HEC-DSS (including the new DSS Vue Program) stores data in a fashion convenient for inventory, retrieval, archiving and model use. The DSS was primarily designed for water resource applications. 

  • 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.

  • HYSEP - Hydrograph separation program performs hydrograph separation, estimating the ground-water, or base flow, component of streamflow.

  • PeakFQ - Performs flood-frequency analysis based on the guidelines delineated in USGS Bulletin 17B

  • 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.

  • SMADA (Stormwater Management and Design Aid) - This software is a complete hydrology package included as a number of separate executable files.

  • SWMM (Storm Water Management Model versions 4.4 and 5) - This Rainfall Runoff Model 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.

  • SWSTAT (Surface-Water STATistics) - contains a number of options for statistically analyzing time-series data.

  • TR-20 (SCS Technical Release No. 20) - Computer Program for Project Formulation Hydrology is a physically based watershed scale runoff event model.

  • TR-55 - Urban Hydrology for Small Watersheds (SCS Technical Release 55) presents simplified procedures to calculate storm runoff volume, peak rate of discharge, hydrographs, and storage volumes required for floodwater reservoirs.

HYDRAULICS:

  • CAP (Culvert Analysis Program) follows USGS standardized procedures for computing flow through culverts

  • CHAMP (Coastal Hazard Analysis Modeling Program) is a program for performing coastal hazard assessments of fine-scale wave phenomena associated with hurricane storm surges or northeaster flooding effects.

  • CHANLPRO numerical modeling system addresses three areas pertinent to the design of channel protection: 1) U.S. Army Corps of Engineers design guidance for riprap  placement in channels, 2) guidance for the design of gabion mattresses, 3) guidance for estimating scour depth in erodible channels.

  • CHECK-RAS is a program designed to verify the validity of an assortment of parameters found in the HEC-RAS hydraulic modeling program.

  • FAN aids in the evaluation and mapping of flood hazards on alluvial fans.

  • Flo2DH is a two-dimensional finite element surface water computer program that can compute the direction of flow and water surface elevation in a horizontal plane.

  • HY-8 Culverts automates the design methods described in the Federal Highways Administration (FHWA) publications HDS-5, "Hydraulic Design of Highway Culverts," HEC-14, "Hydraulic Design of Energy Dissipators for Culverts and Channels," and HEC-19, "Hydrology."

  • Quick-2 is the latest version of a hydraulic analysis program used to compute water-surface elevations in open channels of all types. 

  • RASPLOT produces plots from Corps of Engineers HEC-RAS program output files for use in FEMA Flood Insurance Studies.

  • RUNUP is a DOS-based program for wave runup computation.

  • WHAFIS (Wave Height Analysis for Flood Insurance Studies) is a DOS-based program that uses representative transects to compute wave crest elevations in a given study area.

  • WRAS is a conversion program that takes existing WSP2 data sets and converts them in HEC-RAS format for import into HEC-RAS.

  • WSPRO is a water surface profile computation model that can be used to analyze one-dimensional, gradually-varied, steady flow in open channels.

This CD library collection is available on one CD for only $45. For a more detailed description of each program, go to our WRCS Hydrology & Hydraulics Software Suite web page.

The RIPRAP Design System is a powerful stream bank protection design software package. The RIPRAP Design System determines sizing, layer thickness and gradation of rock riprap to protect streams from scour utilizing seven different methods:

  • US Army Corps of Engineers (Engineer Manual 1110-2-1601)

  • Federal Highway Administration (Hydraulic Engineering Circular No. 11)

  • U.S. Bureau of Reclamation (Engineering Monograph No. 25)

  • U.S. Geological Survey (Water Resources Investigation Report 86-4127)

  • California Bank and Shore Protection Manual

  • Isbash (from USACOE Engineer Manual 1110-2-1601)

  • American Society of Civil Engineers (Manual 54)

Simple single execution window allows the user to quickly compare results.

Streambank Protection Design just doesn't get any easier than this!

HEC Software
Latest Releases

US Army Corps of Engineers
Hydrologic Engineering Center Software

   HEC continues to enhance and introduce new products. Here are the latest releases from the Hydrologic Engineering Center of the US Army Corps of Engineers:

HEC-HMS, Hydrologic Modeling Systems, Version 3.3.
Two new simulation features were added to the HMS Version 3.2 software. They include: a new option in the SCS Unit Hydrograph transform method and a simple reservoir evaporation option. In addition, as with any new release, the identification and repair of a number of bugs also took place.

HEC-SSP, Statistical Software Package,
Version 1.0.

This initial release of the HEC-SSP software begins to replace the multiple DOS based statistical applications that HEC has supported for years. Version 1.0 can perform flood flow frequency analysis based on Bulletin 17B, "Guidelines for Determining Flood Flow Frequency" (1982).

HEC-ResSim, Reservoir System Simulation, Version 3.0.
While the latest version of HEC-ResSim, the Reservoir Simulation model, has not yet been released, it is expected very soon. The next release of HEC-ResSim, Version 3.1, has been in development for almost two years. Beta testing began last summer and is almost complete. Included in this release are several new features as well as some great enhancements to existing features. Most of these developments have been made possible through some unique interagency projects and resource sharing.

Other software that is expected to be released in 2009 include HEC-FIA, Flood Impact Analysis, with its loss-of-life capabilities and the new Watershed Analysis Tool, HEC-WAT, (which includes HMS, RAS, SSP, ResSim, EFM and FIA software).

Detailed descriptions of all of the HEC Programs are available on our HEC Programs web page.
