The objective of this project is to subject a relatively large body of existing data for a surface water impoundment to statistical computations for establishing and quantifying the largely wind-driven circulation and turbulent processes that affect the quality of the impounded water. The impoundment being studied in this project is the Toledo Bend Reservoir on the Sabine River in Texas, characteristic of many highly stratified, water supply and cooling water reservoirs in the United States with a relatively low rate of water-displacement. The results of this project are potentially applicable for use in validating existing mathematical models for characterizing the physical processes that affect circulation in these types of impoundments and influence the quality of the impounded water. This project's results are likely to lead to a better understanding than now exists of mixing and circulation patterns in stratified lakes that have an impact on the quality of the impounded water. This knowledge may be applied to engineering design of new impoundments, operation of existing impoundments, and the location and operation of treatment systems for bringing the water to standards of quality that are appropriate for the intended use.

该项目的目标是对地表水蓄水的相对较大的现有数据进行统计计算，以建立和量化主要由风驱动的循环和湍流过程，这些过程影响蓄水的质量。本项目研究的蓄水是德克萨斯州萨宾河上的托莱多弯水库，它具有美国许多高度分层的供水和冷却水水库的特点，排水量相对较低。这个项目的结果可能适用于验证现有的数学模型，以描述影响这类蓄水池循环和影响蓄水水质的物理过程。​这个项目的结果可能会比现在更好地理解分层湖泊中对蓄水水质有影响的混合和循环模式。这些知识可以应用于新蓄水池的工程设计，现有蓄水池的操作，以及处理系统的位置和操作，以使水达到适合预期用途的质量标准。
