<br />Task 13 <br /> <br />Task 5 includes using the HEC-l model to compare modeled runoff to historic flood data <br />for the Cherry Creek 1935 storm. The primary purpose of this effort is to assist in back <br />calculations of rainfall amounts and comparing the resulting runoff with peak stream flow <br />data. The findings from this effort will provide valuable information to any follow-on <br />projects which address PMF calculations. This task provides an initial evaluation of the <br />parameters provided by the USACE along with determination of additional HEC -1 input <br />parameters needed to make the model runs. The determination of the input parameters <br />includes delineating drainage areas, channel length and slope, identifying soils and <br />respective hydrologic properties, identifying vegetation type and density, and <br />determining channel geometry. <br />
