For these subbasins, the rainfall l1sted above was used w1thout areal <br /> <br />adjustment. However, with the Standley Lake area included, rainfall amounts were <br /> <br />decreased to reflect a 10-20 square-mile areal adjustment. <br /> <br />HEC-l. In this appl1catlon of the HEC-l computer program of the USACE, the hydro- <br />graphs developed using the CUHP program were input as part of the HEC-l model. <br />These hydrographs were supplemented with Information about the channel capacities <br />and how the subbasins relate to one another. The model was run and the total run- <br /> <br />off volumes, hydrographs, and peak discharge rates at various locations In the <br />watershed were determined. <br /> <br />Dlscharoe at C&S Railroad.
