For these subbasins, the rainfall listed above was used without areal <br /> <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 /> <br /> <br />graphs developed using the CUHP program were Input as part of the HEC-l model. <br /> <br />These hydrographs were supplemented WIth information about the channel capacities <br /> <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 /> <br />watershed were determined. <br /> <br />Dlacherae .t C&.S R.lIro.d.
