<br />1'." <br />'.0 <br />c..c <br />r.-. <br /> <br />ABSTRACT <br /> <br />The Pacific Sountwest Interagency committee, 1968, Sediment Yield <br />Procedure is a resource evaluation tool that can be used to <br />characterize sediment and salt yield from various sized <br />hydrologic units, watersheds and geomorphic units. This sediment <br />yield model is a documented reliable procedure that will result. <br />in quantification of sediment and salt yield. A sediment <br />delivery ratio can be applied to derive sediment and salt <br />delivery quantification from the modelled hydrologic unit or <br />watershed to a downstream delivery point. These proposed <br />revisions incorporate recent research into the procedure and <br />improve the utility of the procedure. The revisions include <br />applying the procedure to three planning frameworks: Present <br />Condition, Future Without Project condition and Future with <br />Project Condition, and to a burned watershed (wildfire) <br />condition. All of these planning models procedures can be used <br />in a timely manner for planning purposes or for emergency <br />watershed protection evaluations. A new evaluation sheet is <br />presented for efficient field Use. Emphasis is placed on the <br />necessity of maintaining the field oriented interdiscipinary <br />method of applying the sediment yield model. An example of the <br />use of the revised sediemnt yield model is cited for the Colorado <br />River Basin Rangeland Salinity project, State of Utah, 1990-1991, <br />as conducted by an interagency, interdisciplinary team <br />
