Description

Published by the American Geophysical Union as part of the Water Resources Monograph Series, Volume 6.

This monograph is intended to inform interested and capable persons, who happen not to be specialists in water resources planning, of the issues and alternative strategies related to metropolitan water supply. This involves learning something about the alternative strategies—some ancient and others not yet operational—for increasing water supplies and/or modifying demand so a supply/demand balance is maintained. This also requires an awareness of the complex economic, environmental, and social issues that increasingly compound what once was considered a purely technological problem, to be left to water resource specialists to solve.
