This report describes the hydrodynamic testing and

Attenuation Device. The purpose of the test was to quantify
the wave attenuation characteristics and structural loading
induced by a test program of monochromatic incident waves
on the submerged structure. The device was...
The shallow, poorly-confined, sand and gravel aquifer underlying the lower
Malheur River basin is contaminated by nitrate and metabolites of the herbicide
