Quality Considerations for Water Supply Evaluations
In regions where the water quality of the sources can vary, the beneficial effects of the higher quality water should be considered. This is particularly true in the Southwestern United...

Wave Setup and Design Water Level
During the winter of 1975-76 measurements were made by the Leichtweiss-Institut of the Technical University of Braunschweig at the west coast of the island of Sylt in the North Sea. The...

Engineering Solutions to Bay Area Drought Conditions
California underwent a 2 yr drought from 1976 to 1978 which had a serious effect on all water supplies of the State. In the San Francisco Bay Area, several local water agencies, in conjunction...
