The Federal Emergency Management Agency (FEMA) has developed several programs to support the National Flood Insurance Program (NFIP). The programs that are available for download from this site are included in the tables below. Additional information, including tutorials, user's manuals and guidance documentation, additional guidance and sample data sets are available for certain programs. Links are provided to all available information. Visit this page often to keep up with the available software resources provided by FEMA.

NOTE: The National Flood Frequency (NFF) has been replaced with the National Streamflow Statistics (NSS) program. NSS contains all of the NFF functionality and equations as well as low flow and other probability equations. The NFF program and database have not been changed since 2004 and will no longer be updated or supported.

CHAMP, Version 2.0

Coastal Hazard Analysis Modeling Program (CHAMP) is a Windows-interfaced Visual Basic language program that allows the user to enter data, perform coastal engineering analyses, view and tabulate results and chart summary information for each representative transect along a coastline within a user-friendly graphical interface. With CHAMP, the user can import digital elevation data; perform storm-induced erosion treatments, wave height analyses and wave runup analyses; plot summary graphics of the results and create summary tables and reports in a single environment.

cHECk-RAS, Version 2.0.1

cHECk-RAS is a program designed to verify the validity of an assortment of parameters found in the U.S. Army Corps of Engineers (USACE) HEC-RAS hydraulic modeling program. In cHECk-RAS Version 2.0.1, updates have been made to modernize the program code base, redesign the program interface to be more intuitive and user-friendly, improve and update existing messages generated by the program, develop new messages generated by the program and enhance ‘Help’ and reporting functions.

NFF, Version 3.2*

Version 3 of NFF can be used to:

  • Obtain estimates of flood frequencies for sites in rural (unregulated) ungauged basins.

  • Obtain estimates of flood frequencies for sites in urbanized basins.

  • Estimate maximum floods based on envelope curves developed by Crippen and Bue.

  • Create hydrographs of estimated floods for sites in rural or urban basins and manipulate the appearance of the graphs.

  • Create flood-frequency curves for sites in rural or urban basins and manipulate the appearance of the curves.

  • Obtain improved flood-frequency estimates for gauging stations by weighting estimates obtained from the systematic flood records for the stations with estimates obtained from regression equations.

  • Obtain improved flood-frequency estimates for ungauged sites by weighting estimates obtained from the regression equations with estimates obtained by applying the flow per unit area for an upstream or downstream gauging station to the drainage area for the ungauged site.

  • Save output from the program in text and graphic files.

  • Obtain documentation and instruction for use of the program from help files.

Quick-2, Version 1.0

Quick-2, Version 1.0, is a Microsoft DOS hydraulic analysis program (similar to HEC-2) used to compute water-surface elevations in open channels. Quick-2 was developed to accompany the FEMA guidance manual titled, Managing Floodplain Development in Approximate Zone A Areas. Quick-2 is designed to assist community engineers, architect and engineering firms, developers, and others at the local level that may be required to develop Base Flood Elevations (BFEs) for Special Flood Hazard Areas (SFHAs) that have been designated as Zone A.

Users should note that Quick-2,Version 1.0 only operates on a Disk Operating System (DOS) or DOS emulator, in which FEMA does not maintain.

Quick-2, Version 2.0

Quick-2, Version 2.0, is the latest version of a hydraulic analysis program used to compute water-surface elevations in open channels of all types. Quick-2, Version 2.0 is designed to only run on Operating Systems (OSs) through Windows 98. FEMA does not plan to upgrade for OsS XP and beyond. FEMA suggests using HEC-RAS software for users experiencing issues using version 2.0 on later OSs.

RASPLOT Version 3.0 Beta

The latest version, RASPLOT Version 3.0 Beta replaces RASPLOT Version 2.5.

New Features of RASPLOT 3.0 Beta Include:

  • Floodway Data Table (FDT) creation tool which allows users to easily create FIS report FDTs

  • An option to allow for the exchange of data between the program and FIRM database tables

  • AdobeTM PDF generation and batch merge options

RASPLOT, Version 2.5

RASPLOT Version 2.5 replaces FEMA's FISPLOT program, which is currently used to develop flood profiles.

RUNUP, Version 2.0

RUNUP, Version 2.0, is a DOS-based program for wave runup computation. This program uses stillwater elevation, shore profile and roughness and incident wave condition input information to compute a wave runup elevation that is consistent with the most detailed guidance currently available.

WHAFIS, Version 4.0

Wave Height Analysis for Flood Insurance Studies (WHAFIS), Version 3.0, is a DOS-based program that uses representative transects to compute wave crest elevations in a given study area. Transects are selected considering major topographic, vegetative and cultural features. WHAFIS uses this and other input information to compute an appropriate depth-limited wave height at the seaward end of each transect.
