Testing the waters: 1,4-Dioxane in North Carolina's Cape Fear River Basin
1,4-Dioxane North Carolina Cape Fear River Basin
2015/5/6
rIt was an email from a colleague that tipped off environmental engineer Detlef Knappe of possible 1,4-dioxane contamination in the Cape Fear River Basin, North Carolina's largest watershed and a sour...
Development of Miniature Full Flow and Model Pipeline Probes for Testing of Box Core Samples of Surficial Seabed Sediments
intact and remolded undrained shear strength t-bar and ball toroid and model pipeline testing
2014/10/31
The box corer is a relatively new tool used in the geotechnical community for collection of soft seabed sediments. Miniature full flow and model pipeline probes were developed as tools to characterize...
Measurement of the Hydraulic Conductivity of Gravels Using a Laboratory Permeameter and Silty Sands Using Field Testing with Observation Wells
observation wells permeameter tortuosity
2014/10/31
A new laboratory permeameter was developed for measuring the hydraulic conductivity of gravels ranging from 0.1 to 2 m/s. The release of pneumatic pressure applied to the test specimen induces an unde...
