Description:
Abstract: Recent developments in digital terrain and geospatial database management technology make it possible to protect this investment for existing and future projects to a much greater extent than was possible in the past. The minimum requirement for hydraulics data includes input and output files for all hydraulic models and spatial datasets that are needed to implement the models. (Source: FEMA Guidelines and Specs, Appendix N)
Purpose: Development of a hydraulic model to provide water-surface elevations for floodplain mapping.

Use Constraints: Acknowledgement of FEMA would be appreciated in products derived from these data. This digital data is produced for the purposes of updating/creating a DFIRM database.
Data Quality Information:
Logical Consistency Report: Hydraulic analysis uses all valid existing flood elevation, hydrologic analysis results and other pertinent information for the study area. FEMA approved models are used to compute water surface elevations for required flood events. Computed water surface elevations and topographic data are used to delineate flood hazard boundaries. Roughness coefficients are carefully selected to represent the conditions along stream beds and banks.
Completeness Report: Hydraulic analysis provides water surface elevations at different locations along the stream and for different flooding events. Hydraulic submittal includes key physical data used in the process, model parameters and model output. Data developed in hydrologic analysis are incorporated in hydraulic analysis. Results of hydraulic analysis are used to map Special Flood Hazard Area (SFHA) boundaries. Selection of model parameters (e.g. roughness coefficients, expansion and contraction coefficients, etc) is supported by additional information (e.g. landuse, aerial photo, etc). Model boundary conditions are carefully selected and justified.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report: The hydraulic data consists of study area vector files and associated attributes produced in conjunction with the hardcopy FEMA DFIRM. The published effective FIRM and DFIRM are issued as the official designation of the SFHAs. As such, they are adopted by local communities and form the basis for administration of the NFIP. For these purposes they are authoritative. Provisions exist in the regulation for public review, appeals and corrections of the flood risk information shown to better match real world conditions. As with any engineering analysis of this type, variation from the estimated flood heights and floodplain boundaries is possible. Details of FEMA's requirements for the FISs and flood mapping process that produces these data are available in the Guidelines and Specifications for Flood Map Production Coordination Contractors. Horizontal accuracy was tested by manual comparison of source graphics with hardcopy plots and a symbolized display on an interactive computer graphic system. Independent quality control testing of the hydraulic data was also performed.
