The Characteristics And Genesis Of Stone Stripes In North Central Oregon, John Baine Pyrch
The Characteristics And Genesis Of Stone Stripes In North Central Oregon, John Baine Pyrch
Dissertations and Theses
Stone stripes are linear accumulations of rock debris separated by finer material and oriented down the steepest available slope. In north central Oregon, the stone stripes are composed of basalt fragments and occur where the soil mantle averages less than 1 m in depth. They are best developed in areas of higher elevation, usually from about 900 to 1100 m, and are most prominent on convex to straight slopes of 15 to 30 degrees. The stripes vary from a few meters to over 150 in length, and their widths range from 0.3 to over 3 m. The depth of the …

Broad Spectrum Microwave Systems For Remotely Measuring Soil Moisture Content, W. P. Waite, K. R. Cook, B. B. Bryan
Arkansas Water Resources Center Technical Reports
A theoretical and experimental study of the microwave reflectivity of soils with varying moisture content was conducted. A system was developed to measure reflectivity over a continuous frequency range of 4 to 26.5 GHz, at incidence angles from 10° to 70°, and with both horizontal and vertical polarization. The measurements were found to be extremely accurate for smooth homogeneous surfaces, however, the effects of surface roughness were found to be more severe than predicted due to the discontinuous nature of naturally occurring rough surfaces. An algorithm was developed which used the frequency dependence of the reflectivity to estimate the effective …
