Texas Water Development Board Lower West Fork Trinity 2D BLE 20230731 Version 2.6.5.6 FEMA-DCS-Hydraulics Washington, DC Federal Emergency Management Agency https://hazards.fema.gov Federal Emergency Management Agency 20230731 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 Standards for Flood Risk Analysis and Mapping.) Development of a hydraulic model to provide water-surface elevations for floodplain mapping requires significant investment in time and resources to obtain and process topographic survey data including cross-section and bridge surveys. 20230731 Texas Water Development Board CTP Submission Date In work Unknown -97.9335 -96.8982 33.0049 32.4073 ISO 19115 Topic Category environment

UNIT 12030102 None Acknowledgement of FEMA would be appreciated in products derived from these data. These digital data are produced for the purposes of updating/creating a FIRM Database and/or Flood Risk Products. Original data development environment may vary. Finishing of the data is done using Esri's ArcGIS software. The submitted geodatabase was created using ArcGIS version 10.5. The hydraulic modeling was performed using HEC-RAS. The FIRM Database consists of vector files and associated attributes produced in conjunction with the hardcopy FEMA FIRM. The published effective FIRM and FIRM Database 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 regulations 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 Standards for Flood Risk Analysis and Mapping. Attribute 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 FIRM Database was also performed. Hydraulic analysis uses all valid existing flood elevation, survey, 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. Hydraulics Data Capture submittals match the model output with respect to floodplain boundaries, cross sections, and water surface elevations and their precision. Floodplain boundaries and cross sections are not cartographically modified, and the data may not necessarily agree exactly with the published regulatory FIRM, FIRM Database, flood profiles, and Floodway Data Tables. 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 surveying and 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. Modeled velocities are checked for potential erosion.
