<br />and channel widening. Of the original six cross sections in this reach. five cross sections <br />had lost one or both endpoints due to channel migration or bank erosion. Locating the <br />exact position of these cross sections was impossible but with the original field notes. it <br />was possible to locate the original cross section within approximately 10 ft.. which enables <br />an analysis of the magnitude of the cross section changes throughout this reach. <br /> <br />All of the cross sections surVeyed in 1997 were documented with field notes and <br />photographs. The field notes describe bank and floodplain conditions. vegetation. and <br />channel bed material. The resurveyed cross sections were plotted and overlaid with the <br />original cross section surveys in the early 1980's. All of the cross section plots. original <br />field notes. photos. and endpoint coordinate positions will be transmitted to the U.S. Fish <br />and Wildlife Service in a final report in January 1997. The report will include an analysis <br />of channel morphology changes and comparative study of the original and recent photos <br />of the cross section. <br /> <br />VII. Recommendatiol\s: <br /> <br />The results of this channel morphology study can be incorporated into future flow <br />recommendations for the Vampa and Uttle Snake Rivers. The results can also be used to <br />support analyses of flows and sediment transport as it relates to channel morphology <br />changes in the past 15 years. It is recommended that these cross sections be resurveyed <br />again in five to ten years or after a major flood event to examine and relocate the <br />endpoints. At that time. missing or damaged endpoints should be replaced or repositioned <br />to maintain cross section data base. With the increasing accuracy of the GPS technology. <br />it is also recommended that the endpoint coordinates be checked and. if necessary. <br />reassigned. <br /> <br />VIII.
