3. RIVERINE HYDIlAUUC ANALYSIS FORM _Is Submitted (I'or areas which have detailed flooding: Full input and output listings along with files on diskette (if available) for each of the models listed below (items I, 2, 3, 4. and 5) and summary of the source of input parameters used in the models must be provided. The summary must include a comolete description of any changes made Crom model to model (e.g. duplicate effective model to corrected eft'ective modell At a minimum, the Duplicate Effective (item 1) and the Revised or Post-Project Conditions (item 4) models must be submitted. See instructions for directions on when other models may be required. For areas which do not have detailed flooding: Only thelOO-year flood profile is required. A hydraulic model is not required for areas which do not have deteiled flooding; however, BFEs may not be added to the revisec! FIRM. If a hydraulic model is developed for the area, items 3 and 4 described below must be submitted. - . IChydraulic models are not developed, hydraulic analyses for existing or pre-project conditions and revised or post- project conditions must be submitted. All calculations must be submitted for these analyses. (See item 6 below) 1. Duplicate Effective Model Natural Floodway Copies of the hydraulic analysis used in the effective FIS, reCerred to as the l!!9 lI!I effective models (lO-, 50-, 100-, and 500-Y<<Jr multi-profile runa and llu floodway run) must be obteined and then reproducecl on the requestor's equipment to produce the duolicate effective model. This is required to assure that the effective model input date has been transCerred correctly to the requestor's equipment and to assure that the revised data will be integrated into the effective date to provide a continuous FIS model upstream and downstream oCthe revised reach. 2. Corrected Effective Model The corrected effective model is the model that corrects any errors that occur in the duolicate effective model. adds any additional cross sections to the dUDlicate effective model. or incorporates more detailed topographic information than that used in the currently effective model. The correctecl effective model must!!2!: reflect any man-made physical changes since the date of the effective model. An error could be a technical error in the modeling procedures, or any construction in the floodplain that occurred prior to the daLe of the effective model but was not incorporated into the effective model. 3. Existing or Pre-Project Conditions Model The duolicate effective or corrected model is modified to produce the existinll or Dre-Droiect conditions model to reflect any modifications that have occurred within the floodplain since the date of the effective model but prior to the construction of the project for which the revision is being requested. If no modification has occurred since the date of the effective model, then this model would be identical to the corrected effective or dUDlicate effective model. 4. Revised or Post-Project Conditions Model The existinsr or Dre-oroiect conditions model (or duplicate effective or corrected effective model, cg appropriGte) is revised to reflect revised or post- project conditions. This model must incorporate any physical changes to the floodplain since the effective model was produced as well as the effects of the project. When the request is Cor proposed project this model should reflect proposed conditions. 5. Other: Please attech a sheet describing all other models submitted. 6. Hydraulic Analyses (Only ifHydraul\c Models are not developed) Please attach all calculations Cor the existing or pre-project conditions and the re.vised or post-project conditions.
