All but one crossing is a culvert, and the culverts were <br />modeled with the culvert option in HEC-RAS. <br /> <br />Small pedestrian path crossings over the channel were assumed to be obstructions <br />without conveyance below the crossings. These crossings were usually hard coded into <br />the HEC-RAS model, which can result in an inverse slope for a short distance in the <br />profile. <br /> <br />-24- <br /> <br />-.--~. .-". ~-._._- <br />
