The composite damage , functions of all grid cells assigned land <br />'use category 1 are truncated to the specified protection level. The process <br />is repeated for other flood proofed land use categories usinQ their modified <br />composite damage functions. ' <br /> <br />2. An elevation-damage curve is developed for each grid cell (composite <br />damage function plus assigned topo elevation) in the damage reach. <br /> <br />3. The elevation-damage curves are adjusted by the reference flood <br />elevation of the grid cell and index location and aggregated to the index <br />location to generate the total elevation-damage relationship for the damage <br />reach. <br /> <br />FIG. 4.--Flood Proofing Selected land Use, Categories to a Specified Stage <br /> <br />11 <br />
