vi . Model Results Reporting <br /> A modeling report will be prepared as an appendix to the BPP . The report will document the data <br /> collection , model setup , calibration , and specific results of the modeling effort. The information to be <br /> included will be as follows : <br /> • Model set- up and features . <br /> • Grid development and characteristics . <br /> • A summary of the bathymetric and wave data used in the modeling and analysis . <br /> • An explanation of model calibration and application for the wave cases examined . <br /> • The parameters and processes utilized in the DeIft3D modeling package . <br /> The appendix will conform to FDEP' s guidelines for DeIft3D modeling studies . <br /> Task 6 : Coastal Modeling = Vulnerability Analysis <br /> CPE will perform a storm damage vulnerability analysis for Indian River County . The analysis will <br /> utilize the Storm Induced Beach Change Model , SBEACH , developed by Larson and Kraus ( Larson <br /> and Kraus , 1989) for the US Army Corps of Engineers ( USACE) . SBEACH simulates changes in the <br /> beach profile that could result from coastal storms of varying intensity in terms of storm tide <br /> levels , <br /> wave heights , wave periods , and storm duration . Information required as input to run the SBEACH <br /> model includes the beach cross-section , the median sediment grain size , and the time histories of the <br /> wave height , wave period , and water elevation . This information will be gathered from existing data <br /> sources . No new collection of data is proposed . If it is determined that the available data is insufficient <br /> to develop an accurate model then collection of additional data will be discussed with the County. The <br /> current assessment is that the available data should be sufficient . <br /> CPE will develop a suite of storms for 4 different return intervals ( 5 -years , 10-years , 20-years , and 30- <br /> years) . Each return interval will have 6 distinct storms . Each of the storms will have one characteristic <br /> (wave height , peak wave period , or storm stage) that matches the value of the return interval for that <br /> characteristic . The other characteristics will be scaled in relation to the scaling of the characteristic <br /> intended to match the return interval . For example , if the maximum offshore wave height for a 5-year <br /> storm event is 20 feet , then we would take an actual storm event that had a maximum wave height of <br /> 16 feet and increase all the storm characteristics by 25 % . <br /> The model will be run for all 119 profile lines within the County . With 24 storm events per profile , a total <br /> of 2 , 856 model runs will be performed . <br /> The pre and post-storm profiles will be compared for each storm event and the most landward <br /> reduction in profile height by 0 . 5 feet and 1 . 0 feet identified . This will be translated <br /> to a plan view <br /> location within a GIS map . Thus an area of expected " land loss" and expected damage can <br /> be <br /> estimated for each return interval . CPE will calculate the expected land loss and the associated land <br /> value along the length of the County . CPE will include the expected damage costs on a structure by <br /> structure basis if the County can provide , in GIS format , structure values and locations . It is beyond the <br /> scope of this work to digitize the outline of each structure and match its value from County Property <br /> records . This additional effort would provide a more accurate assessment of projected damage but is <br />
