Abstract : Quantitative geomorphic measurements were made on modern 1:24,000-scale topographic maps for 90 order-3 and 90 magnitude-10 basins randomly selected from a 250 square-mile area of horizontal, homogeneous sandstones in eastern Kentucky. Operator variations were greatest in locating sources and least in measuring areas, and were readily reduced to acceptable limits by training and practice. Similar measurements were made on 153 magnitude-5 basins in the study area. The sample is approximately topologically random with weak, but apparently systematic, deviation. (Author)
