Primary Water Resources Data-Base for the Second National Water Assessment (Magnetic Tape Documentation)

摘要

The Second National Water Assessment by the U.S. Water Resources Council presents a comprehensive nationally consistent data base for the 21 water resources regions of the United States, published in report format in four volumes as 'The Nation's Water Resources--1975-2000' (December 1978, through GPO). The magnetic tape contains much of the data presented in 'Volume 3, Analytical Data.' Information is presented not only for the 21 water resources regions, but for 106 water assessment subregions that provide more localized information. Information is presented for present (1975) and future (1985 and 2000) conditions.
