在1984年的大部分时间里，在德克萨斯州科珀斯克里斯蒂地区持续干旱期间，对户外用水和水配给的强制限制分阶段实施。本文给出了一种方法，将保护对日常用水的影响与天气和季节变化的同时影响分开，从而能够对保护限制进行定量估计。结果表明，与峰值用水量约为100 mgd相比，限制措施平均减少了29 mgd的用水量。由于用水量已降至冬季基准水平，随后实施的更严格限制措施几乎没有带来额外节约。 研究还表明，保护的剩余效应一直延续到1985年，甚至在取消限制之后。包括10个参考文献、表格和图表。

Mandatory restrictions on outdoor water use and water rationing were implemented in stages in Corpus Christi, Texas, during the course of a regional drought lasting through most of 1984. This article gives a methodology for separating the effects of conservation on daily water use from concurrent effects of weather and seasonal variation, enabling a quantitative estimate of the conservation restrictions to be made. It is shown that the restrictions reduced water use by an average of 29 mgd, compared with a peak water-use of about 100 mgd. Subsequent implementation of more stringent restrictions resulted in little additional savings because water use had already decreased to winter base levels. It is also shown that the residual effects of conservation extended through 1985, even after the restrictions were lifted. Includes 10 references, tables, figures.
