Streamflow Generation from Subalpine Forests
Much of the hydrologic modelling done in the subalpine forest of the central Rockies is based on the Subalpine Water Balance Model. This paper reports on plot studies on the Fraser Experimental...

Prediction of Soil Water Properties for Hydrologic Modeling
Water flow in soils can be characterized for many boundary and initial conditions by solving governing differential equations. Thus, a physically consistent means of quantifying water...

A Systematic Evaluation of Hillslope Subsurface Flow: The Effects of Slope Angle and Soil Parameter Variation
A two-dimensional finite element variably saturated flow model is used in conjunction with an automatic mesh generating scheme to simulate hillslope subsurface flow. Slopes from 2% to...

Computer Modeling of Roof Support
The Bureau of Mines is using a full-scale geotechnical model of a 15-foot-wide (4. 6-m) coal mine entry in correlation with computer finite-element analysis at its Spokane Research Center...

Modelling of the Fracture Process Zone in Rock
There are a number of situations in the fracture mechanics of rock in which linear elastic fracture mechanics (LEFM) concepts are inapplicable or insufficient. Two such situations are...

Prediction of Highway Construction Noise Levels
A model for the prediction of noise levels from highway construction operations has been developed under sponsorship of the Federal Highway Administration (FHWA). Noise sources are geometrically...

Dynamic-Fatigue Response of Continuous Composite Bridges
The dynamic response of continuous composite bridges and the influence of fatigue loading at resonance frequency on the structural response are investigated. It is shown that cracking...

Strength of Biaxially Loaded SRC Columns
The paper presents the results of an experimental study on the elasto-plastic behavior of 'Steel reinforced concrete (SRC)' columns subjected to biaxially eccentric...
