本文描述了以哈德逊河为代表的部分分层水体的水动力学特征，并提出了建立密度诱导流速和环流与盐度、淡水径流和潮汐特征的定量关系的若干方法。这些方法利用已知的或可测量的物理和水力参数来确定河口的密度诱导循环（DIC）和混合特性。DIC概念在河口排放中起着重要的作用，并已被用于获得河口稀释可用流量的估计。与此DIC模式相关的稀释流可能是高地径流的许多倍。据观察，在几个河口，它们的系数从10到40不等。本文第二部分B对河口环流型作了简要的描述。第三部分讨论部分分层河口的环流型。这些模式与净速度分布有关，净速度分布大体上是潮流与密度或盐度分布之间的动态相互作用的结果。在不同密度的沃茨相互接触的系统中，河流高地径流的存在和由潮汐引起的湍流产生的垂直混合控制了这些分布。第四部分d提出了一些分析和经验的方法来发展DIC和河口稀释流的定量关系，以主导系统参数，特别是淡水流量和盐浓度。第五部分e采用这些方法来估计在各种水动力和气象条件下的哈德逊河DIC流量。本文中总结的许多研究是近年来在作者的监督下，作为Quirk、Lawler和Matusky工程师公司对哈德逊河主干沿着工业排放的持续工作的一部分进行的。此外，这里报告的大部分分析调查都是作为一个正在进行的研究计划的一部分进行的。I6这些研究被用作本文的信息来源，并被适当引用。
This paper describes the hydrodynamic characteristics of partially stratified water bodies, as typified by the Hudson River, and presents a number of methods of establishing a quantitative relationship of density-induced velocity and circulation to salinity levels, freshwater runoff, and tidal characteristics. These methods utilize known or measurable physical and hydraulic parameters to determine the density-induced circulation (DIC) and mixing characteristics of estuaries. The DIC concept plays an important role in estuarine discharges, and has been used to obtain an estimate of the flow available for dilution in estuaries. Dilution flows associated with this DIC pattern may be many times that of the upland runoff. They have been observed to be higher by factors of from 10 to 40 in several estuaries. A brief description of estuarine circulation patterns is given in the second section b of this paper. The third section c addresses itself to circulation patterns in partially stratified estuaries. These patterns are related to the net velocity distribution, which by and large is a result of dynamic interactions between the tidal current and density or salinity distributions. The presence of river upland runoff in a system in which waters of different density are brought into contact with each other and vertical mixing generated by tide-induced turbulence control these distributions. The fourth section d presents a number of analytical and empirical approaches to the development of a quantitative relationship of DIC and estuary dilution flow to dominating system parameters, particularly freshwater flow and salt concentration. The fifth section e employs these approaches to estimate DIC flows in the Hudson River under various hydrodynamic and meteorological conditions. Many of the studies summarized in this paper were conducted in recent years as part of Quirk, Lawler & Matusky Engineers’ continuing work effort on industrial discharges along the main stem of the Hudson River, under the author’s supervision. Additionally, much of the analytical investigations reported here have been conducted as part of an ongoing research program.I6 These studies are used as sources of information for this paper and are duly referenced.
