Effects of Timber Harvesting on Groundwater Level and Slope Stability in Deeply Weathered Material

Purpose

Effects of timber harvest on groundwater level and slope stability in deeply weathered material. Areas will be clear-cut when sufficient data on the water table and soil creep has been collected. The researchers anticipate about a 5 yr. period to develo

Consequences of Canopy Interception for Stability of Slopes

Purpose

For field validation of a model that will describe the short term variation in canopy storage of rainfall. The goal is to determine 1)the contribution of canopy interception of rainfall to stability of slopes by its effects on short term water balance on
