| Abstract: | Forecasting off-road trafficability represents an interesting problem in the earth science field, since variables ranging from solar insolation to soil shear strength are involved. However, existing trafficability models do not include precipitation-soil moisture deterministic submodels. Instead, they frequently commence with soil moisture and invoke empirical relationships to predict trafficability. This investigation couples a deterministic soil moisture submodel to a principal empirical soil moisture-trafficability model. Sensitivity analysis shows the impact cloud cover, as well as other variables, can have on the trafficability of three soil types, and the complexity of the post-storm trafficability response. |
