The source of most of Oahu's domestic water supply is from ground water occurring in the permeable materials of volcanic rock. Movement of the ground water is intrinsically through thin cracks in basaltic
lavas. This project studied passage of an...

Two remote sensing techniques of measuring offshore ground-water spring discharge that have been studied are: (i) multispectral photography, and (ii) infrared thermometry.
During the summer of 1967, exposure factors for filter-film-camera...
