Conse- <br /> <br />quently, soil depth measurements were conducted in Basins A, N. Q, <br /> <br />S. T. and U, only. The basin characteristics were analyzed in order <br /> <br />to determine inter- and intrabasin correlations that would be useful for <br /> <br />describing erosional processes in the badlands. <br /> <br />Longitudinal profiles of the main channel and several major tribu- <br /> <br />taries were measured, as well as several valley cross sections. in each <br /> <br />of the eight basins. Channel length was measured along the center of <br /> <br />each channel. Change in channel elevation was measured with a level <br /> <br />alidade and a stadia rod. Where channels were incised into alluvial <br /> <br />fill, profiles were surveyed along the channel bottom and on the surface <br /> <br />of the alluvial fill immediately adjacent to the channel. The plane <br /> <br />table and alidade method. as described by Compton (1962), was <br /> <br />employed to measure the valley cross sections at roughly equally spaced <br /> <br />locations along the basin lengths. <br /> <br />A hand trowel was used to dig pits for the purpose of measuring <br /> <br />soil depth. Soil. as used in this study. is defined as the layer of <br /> <br />material derived from underlying weathered, yet structurally distinct, <br /> <br />bedrock. Soil depth sites included both divides. both hillslopes. and <br /> <br />channel bottoms. <br /> <br />The soil depth data were analyzed for inter- and intrabasin <br /> <br />relationships. An analysis of variance was conducted to determine the <br /> <br />significance of difference between the soil depth means for: basin <br /> <br />divides and basin hillslopes within each basin; and for each basin <br /> <br />within two sets of basins according to underlying bedrock type.
