Introduction: The general project of correlating soil properties with geologic information and with simple soil index characteristics, one phase of which is described in this report, consists in comparing soil properties with soil types and with their geologic history and environment in order to determine what correlations are possible.

"The purpose of this report is to present the results of a study of the performance of the three relief well systems [along the Missouri River] during the July 1951 and April 1952 floods, and to compare their performance with design predictions. [...] The report includes observed uplift and well-flow data, descriptions of relief well operations during the floods, and an analysis of the effectiveness of the well systems together with discussion and comments on several experimental and test wells" (p. 2).

Summary of trafficability studies conducted by the Waterways Experiment Station. It includes information about phase I tests related to "Soil Classification and Trafficability Data" as a sub-project of "Trafficability of Soils as Related to the Mobility of Military Vehicles" (published 1947-1955). It also includes initial results of phase II, "Soils Trafficability Predictions."
