Workshop on: Water Science and Engineering in River Impoundments, Status, Information Gaps and Research Priorities; Murray, Kentucky; April 9-12, 1989

大坝及其附属水库的建造是为了各种目的，包括防洪、发电、蓄水、航行等，所有这些都涉及到大坝的运行。有关运营的决定伴随着大坝的存在。在这一点上，水库与天然湖泊有着本质的区别，但水库中也会出现与天然湖泊相似的现象。这些现象在多大程度上受到水库河流特征的显著影响，因此引起了湖泊学的兴趣。随着大坝建设的极限接近，随着水质问题变得更加优先，随着人口、经济和法律改变了用水者的法律地位，现在正在更加认真地处理可能带来额外利益的业务变化。因此，大坝运行对水库本身和下游蓄水河流的影响不可避免地将基础（科学）和应用（管理）联系在一起。建议举办一个讲习班，重点讨论水库科学以及对水生生态系统感兴趣的几个学科之间的相互作用。这些包括：(1)基于物理的建模者，(2)基于生物学的建模者，(3)经验地球科学家（地球化学，生态学，水文学），(4)实验生态学家。这次会议的会议记录草案将记录科学的现状，并从科学家的角度确定信息的差距。这次水库湖沼学家和基础科学家的跨学科会议的结果将发表在一卷中，对这一主要水生群落感兴趣的人将很容易获得。

Dams and their attendant reservoirs are built for various purposes, including flood control, power generation, water storage, navigation, etc., all of which involve the operation of the dam. Decisions about operations accompany the existence of dams. In this regard, reservoirs are essentially different from natural lakes, however, phenomena similar to natural lakes occur in them. The degree to which these phenomena are significantly influenced by the riverine character of reservoirs is significant and, therefore, of limnological interest. Changes in operations which might carry additional benefits are now being addressed more seriously as the limits of dam construction are approached, as water quality issues become of higher priority and as demography, economics and law alter the legal standing of water users. Thus, the influence of dam operations on the reservoirs themselves and on downstream reaches of the impounded river unavoidably links the basic (science) and the applied (management). A workshop is proposed which will focus on reservoir science with interactions among several disciplines interested in aquatic ecosystems. These include: (1) the physics based modelers, (2) the biology based modelers, (3) empirical earth scientists (geochemistry, ecology, hydrology), and (4) experimental ecologists. A draft of the proceedings of this meeting will document the status of the science and identify gaps in information from the perspective of the scientists. Results from this interdisciplinary meeting of reservoir limnologists and basic scientists will be published in a volume which will be easily accessible for those interested in this major aquatic community.
