<br />has been only limited research about sediment transport and the geomorphic <br /> <br />characteristics of this river system. Increased attention was focused on the hydrology <br /> <br /> <br />and geomorphology of the White River in the mid-1970s due to oil shale exploration in <br /> <br /> <br />the region. Between 1974 and 1980, the U.S. Geological Survey (USGS) established <br /> <br /> <br />baseline discharge and water quality data in anticipation of widespread oil shale <br /> <br /> <br />extraction in the region (Lindskov and Kimba11984). Suspended sediment transport <br /> <br /> <br />measurements at the Watson gage were made on a daily basis for most of water year <br /> <br />1975, and these data are used in this study. Bedload transport was estimated from <br /> <br /> <br />observed changes in mean channel depth during high flows at a gage temporarily located <br /> <br /> <br />near the mouth of the White River (station 09306900) (Seiler and Tooley 1982). During <br /> <br /> <br />a flood of 4, 100 cfs, the bed scoured roughly 1 m at this site. They estimated that <br /> <br /> <br />approximately 1.3 x 106 m3 of bed material was scoured and filled in 18 rm upstream <br /> <br />from the gage during this flood. Jurado and Fields (1978) used airphotos taken as early <br /> <br />as 1936 to document long-term changes in channel position throughout the White River. <br /> <br />They found that the White River is prone to channel migrations, and that the degree of <br /> <br />channel migration is dependent on specific reach characteristics such as slope and degree <br /> <br />of bedrock confinement. During the past century, the channel has migrated less in <br /> <br />reaches of high slope and narrow bedrock 'confinement. <br /> <br />The listing of four endemic fishes as endangered species, including the Colorado <br /> <br />pikeminnow, has also increased attention on the hydrology and geomorphology of the <br /> <br /> <br />White River. Changing hydraulic and geomorphic conditions influence physical habitat <br /> <br /> <br />features such as the size and frequency of eddies (Orchard and Schmidt 1998), and the <br /> <br /> <br />amount of fine-grained sediment located in the interstitial spaces in gravel bars (Kondo If <br /> <br /> <br />4 <br />
