RISClosure to “Design Method for Geogrid-Reinforced Unpaved Roads. I: Development of Design Method” by J. P. Giroud and Jie Han
Publisher: American Society of Civil Engineers
Design Method for Geogrid-Reinforced Unpaved Roads. I. Development of Design Method
Publisher: American Society of Civil Engineers
Abstract: A theoretically based design method for the thickness of the base course of unpaved roads is developed in this paper, which considers distribution of stress, strength of base course material, interlock between geosynthetic ...
Design Method for Geogrid-Reinforced Unpaved Roads. II. Calibration and Applications
Publisher: American Society of Civil Engineers
Abstract: A theoretically based base course thickness design method for unpaved roads was developed in the companion paper. This paper presents a calibration of the design method using data from field wheel load tests and laboratory ...
Degree of Turbulence of Flow in Geosynthetic and Granular Drains
Publisher: American Society of Civil Engineers
Abstract: Flow in porous media, such as geosynthetic and granular drains, is often nonlaminar. Nonlaminar flow can vary in character from semiturbulent to turbulent, depending upon the flow velocity, which is related to the hydraulic ...
Mapping Flash Flood Severity in the United States
Publisher: American Meteorological Society
Abstract: lash floods, a subset of floods, are a particularly damaging natural hazard worldwide because of their multidisciplinary nature, difficulty in forecasting, and fast onset that limits emergency responses. In this study, a ...
Nonintrusive Measurement of Ocean Waves: Lidar Wave Gauge
Publisher: American Meteorological Society
Abstract: In December 1999, a nonintrusive directional lidar wave gauge (LWG) was field tested at the Field Research Facility (FRF) in North Carolina. The LWG uses proven lidar technology to directly measure water surface elevation ...
