<br />Curve Number Table. A card image of each LU card is shown in Exhibit <br />3-l (12). The Curve Number table identifies the Curve Numbers assigned to <br />each hydrologic soil group within a given land use category (13). <br /> <br />Subbasin Parameter Cards. Card images of the SB card input are also <br />included (14). This display provides an opportunity to check the input <br />values of the subbasin data. <br /> <br />Subbasin Summary Table. For each subbasin under analysis, the stream <br />length (miles), length to the centroid of the area (miles), stream slope <br />(feet per mile), and the HYDPAR subbasin designation are given (l5). (The <br />centroid length is not needed for this computational technique and the HEC-l <br />stations are required only when the results are saved for automated inter- <br />face with the HEC-l computer program). <br /> <br />Specific Subbasin Data. Computational results are printed sequentially <br /> <br /> <br />for each subbasin. Each subbasin is identified (l6) and the land use cate- <br /> <br /> <br />gories that exist within its boundary are listed. For each identified land <br /> <br /> <br />use, data is printed for four headings: Average Curve Number, surface slope <br /> <br /> <br />(percent), area in acres, and percent of the subbasin that is occupied by a <br /> <br /> <br />specific land use (l7). For each subbasin, the computed average values of <br /> <br /> <br />Curve Number and surface slope are given (l8). The percentage of the sub- <br /> <br /> <br />basin area associated with a given land use is used to weight the curve num- <br /> <br /> <br />ber and surface slope and the weighted values are then used to produce the <br /> <br /> <br />subbasin averages. A tabulation of pertinent data and computed hydrologic <br /> <br />parameters is also printed (l9). (It should be noted that in this instance <br /> <br /> <br />stream length and slope were input directly). <br /> <br />Summary of Subbasin Data. The summary output is a condensed ver- <br />sion of subbasin data (20). Each subbasin is identified and for each sub- <br />basin, computed values of drainage area, percent of watershed (represented <br />by the identified subbasin), average curve number, subbasin lag, and subbasin <br />slope are given. (The stream length and slope values were provided initially <br />with the input data). <br /> <br />3-l2 <br />
