Trafficability of Soils: Eighteenth Supplement, Development of Revised Mobility Index Formula for Self-Propelled Wheeled Vehicles in Fine-Grained Soils

Description: The main purposes of this study were to (a) obtain adequate test data to determine experimentally the vehicle cone index (VCI) for 50 passes for vehicles mounted with nonconventional tires and (b) use results of the field tests to develop a revised mobility index (MI) formula for self-propelled wheeled vehicles.

An Analytical Model for Predicting Cross-Country Vehicle Performance, Appendix B: Vehicle Performance in Lateral and Longitudinal Obstacles (Vegetation), Volume 1: Lateral Obstacles

Description: First part of an appendix that accompanies a study meant to develop a model for predicting the cross-country performance of military vehicles in various conditions. This volume describes a segment of tests to determine the ability of vehicles to negotiate lateral obstacles (e.g., trees, boulders, holes, mounds, etc.).

Acoustic Flowmeter Prototype Evaluation Tests

Description: Summary: "Prototype tests of an acoustic flowmeter system were made in a 24-ftdiam power penstock at Oahe Dam to evaluate the system prior to permanent installation in the outlet works at Summersville Dam. Comparative discharge measurements included acoustic, penstock pressure-momentum (Gibson), turbine model test ratings, scroll-case pressure differential (Winter-Kennedy flowmeter), and surge tank volume changes. The acoustic flowmeter measurements were very consistent and many of the comparisons were within 1%. The location of the measuring section for a single-path acoustic flowmeter must be selected to give a known or measurable relation between the flow pattern of the whole section and that along the acoustic path" (p. xi).

Investigation of Membrane Stack Resistance Increase With a Natural Brackish Water

Description: From Introduction: "An investigation was undertaken by the Bureau of Reclamation to identify the cause of causes of this problem with a particular brackish water. The resistance increase of is of great concern principally because of the increase in power consumption that ultimately contributes to a higher cost for product water. Reports show that membrane stack resistance has increased as much as 200 percent over period of several days."
