A study was conducted of parameters used to adequately describe soil strength for trafficability as related to changes in moisture. Modeling the weather conditions in combination with the terrain will create dynamically changing soil conditions. Off-road predictions of mobility, the detection of buried ordnance, and expedient horizontal construction require a firm understanding of these temporal and spatial changes in the heterogeneous soil system. To validate and verify the soil parameters used to drive a model, rapid and repeatable methods of measuring the soil strength and related physical properties are desired.
