<br />mobilizing sediment, maintaining saturated conditions within the fine sediments, and <br />limiting the residence time of sediment in pools. <br /> <br />Other Jvfanagement Constraints <br /> <br /> <br />Often, other conditions such as funding, personnel, or water limitations may <br /> <br /> <br />dictate management decisions regarding ways to prevent or mitigate sedimentation <br /> <br /> <br />hazards. Should availability or expense of water for flushing flows be prohibitive, <br /> <br /> <br />sediment transport modeling would be useful to determine a minimum magnitude and <br /> <br /> <br />duration necessary to recover pool volume. First, however, decisions regarding the <br /> <br /> <br />desired pool volume recovered would be necessary, and then the modeling could be <br /> <br /> <br />directed at that goal. The uncertainty of such a study depends on the quality and quantity <br /> <br /> <br />of the input data. and the expertise of the modeler. <br /> <br /> <br />In situations were water availability and expense are unconstrained, stepped <br /> <br /> <br />experimental releases, preferably several in sequence are recommended, to the maximum <br /> <br /> <br />capacity of the dam structure, Minimizing sediment deposition initially, during a <br /> <br /> <br />sediment release. would minimize the hazards that beset the North Fork after the release <br /> <br /> <br />in September 1996, <br /> <br />15 <br />
