The quantitative analysis of topography conducted in this study shows that considerable spatial variability of slope steepness occurs between differing slope aspects of large areas in the Palouse. This information could be used in developing improved runoff and erosion prediction models that account for spatial variability of topography over large areas. Gaussian frequency distributions provided the best statistical description of the data.
7464. Weaver, J.E. and W.C. Noll. 1935. Comparison of runoff and erosion in prairie, pasture, and cultivated land.. Conservation Dept. Bull. 11, Univ. Nebraska, Lincoln, NE.
Relative runoff from 27" rainfall over 15 months on plots with 10% slope: prairie 2.5%; overgrazed pasture 9.1%; bare soil 15.1%. Water penetration was nearly four times as great in prairie as in pasture. Even with runoff, no measurable erosion occurred on any of the grassed plots.

Windbreaks are valuable for reducing soil erosion and lowering evaporative stress on crops, leading to higher yields. Crop yields begin to decline at a distance from the windbreak of about 5 times its height.
