Abstract

The purpose of this study is an investigation of slope development by statistical analysis of slope angle, slope length, relief and stream gradient data developed on four different glacial drift deposits in Iowa. Measurement from randomly selected points on 1:24,000 topographic maps provide the data. Analysis of variance is used with both F-ratios and between-group t-tests. Differences from comparisons based on the age of the different glacial drifts were found to be significant for all parameters. Significant differences were also found for some of the variables in comparisons based on physiographic classification, stream order of the nearest stream, and orientation of the slope. Relationships among the variables are indicated by correlation coefficients with significance determined by t-tests.
