Abstract or Summary
  • A Stream Reach Inventory and Channel Stability Evaluation procedure has been used to assess the nature and extent of erosional nonpoint sources of pollution in the Evans Creek basin, a tributary to the Rogue River, in southwestern Oregon. The study is based upon the results of the Oregon Department of Environmental Quality Section 208 Nonpoint Source Assessment Project. A terrain analysis of Evans Creek has been performed using quantitative basin morphologic techniques. Regressions analysis techniques were used to relate the channel stability conditions of the streams of Evans Creek to the morphologic characteristics of the basins. The Channel Stability Rating procedure is demonstrated to distinguish differences in the stability of channels under varying conditions of land use and lithology. The inventory procedure identifies and represents in-stream erosional and depositional processes differentially. Quantitative basin morphologic investigations indicate that streams in the. Evans Creek basin generally conform to hydrophysical laws of drainage composition. Channel stability has been significantly related to 20 morphologic variables describing areal, linear, textural, relief and shape aspects of the Evans Creek basin in streams logged six to ten years ago, in second growth and in old growth. Channel stability ratings appear to be related to watershed characteristics which reflect the development of potential energy in a drainage basin and influence the way potential energy is expended in the channel system.
