<br />STEP 11 <br /> <br />DETERMINE APPROXIMATE FLOOD ELEVATION <br /> <br />Whether you have used the Continui!~~ Equation (Method 1) or <br />the Manning's Equation (Method 2), you have now calculated a <br />flood depth at each crossnsection. <br /> <br />At each cross-section )'011 should hav'~ a <br />Channel Bottom Elevation that is tied to <br />the Assumed Benchmllllrk for the site (i.e. <br />top of curb, bridge abutment, foundalion), <br /> <br />Add the Flood Depth at each cwss..seetion to <br />Channel Bottom Elevation at that cross-seetion, <br /> <br />That sum is the F'lood Elevation for the <br />cross-section. <br />
