Available in PDF, EPUB and Kindle. Book excerpt: An experimental and analytical study of the basic factors which determine the instantaneous longitudinal distribution of salinity in a partially mixed estuary of constant section is presented. The mass-transfer equation is solved in two parts: (a) the quasi-steady-state convective-diffusion problem for an observer moving with the tidal velocity, and (b) the cyclic translation of saline water due to the tidal velocity. In the steady-state portion the apparent longitudinal diffusion coefficient is a function of the turbulence induced by the tide and of the internal circulations induced by the density difference. An expression is developed for the intrusion length as a function of the estuary length, mean depth, tidal amplitude and period, fresh-water discharge, ocean salinity, and estuary roughness. A stratification number is defined which expresses the degree of stratification or mixing in an estuary. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Water Pollution Research, Volume 1, documents the proceedings of the Second International Conference on Water Pollution Research held in Tokyo, August 1964. The past decade has seen a rapid increase in water pollution research activity in all parts of the world. The vast research activities in Japan and the impact of this activity on all of Southeast Asia led to the unanimous decision to hold the Second International Conference in Japan. This volume contains 16 papers that deal with topics such as the microbiological and virological aspects of water pollution; the impact of toxic substances on fish; research on heavy metal pollution; residual toxic effects of organic phosphorus insecticides in water; and mechanisms of uptake and release of radionuclides by stream sediments. Also included are the opening address by Conference President, Dr. Korokuro Hirose, Professor Emeritus of Tokyo University, and keynote address by A. Key of the Ministry of Housing and Local Government, London, England.

This book was released on 1972 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The salinity structure of a tidal estuary fed by upstream fresh water sources is an important factor of water quality. In addition, this structure is intimately related to the circulation of the estuary because of density currents induced by the salt-fresh water relation. Previous investigations in two and three dimensions have been limited to extremely simplified geometrical and steady-state assumptions. One dimensional studies have considered the variable area case, but have been limited to descriptive rather than predictive methods because of the difficulty of handling the downstream boundary condition for the one-dimensional salt balance equation and because of the necessity to specify a longitudinal dispersion coefficient based on field data for the estuary being studied. This study presents a predictive numerical model of unsteady salinity intrusion in estuaries by formulating the problem in finite-difference terms using the one-dimensional, tidal time, variable area equations for the conservation of water mass, conservation of momentum and conservation of salt. Tidal time means a time scale of calculation larger than that defining turbulence, but much smaller than a tidal period in order to correctly represent the tidal advection within a tidal period. The tidal dynamic equations are coupled to the conservation of salt equation through a salinity-density relationship, and the ocean boundary condition for salt is formulated in a manner which depends on the direction of flow at the entrance to the estuary. The longitudinal dispersion coefficient has been shown to be proportional to the magnitude of the local, time-varying longitudinal salinity gradient, and this constant of proportionality has been shown to depend on a dimensionless parameter which expresses the degree of vertical stratification of the estuary. This relationship has been established for a wide range of stratification conditions. The mathematical model has been verified using data from the Waterways Experiment Station salinity flume and field data from the Delaware, the Potomac, and the Hudson. By specifying initial conditions, fresh water hydrographs, and tidal elevations at the ocean, it is possible to predict the time-varying salinity using this model.

Book Synopsis Salinity Effects on Velocity Distributions in an Idealized Estuary by : Donald R. F. Harleman
Download or read book Salinity Effects on Velocity Distributions in an Idealized Estuary written by Donald R. F. Harleman and published by . This book was released on 1962 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental and analytical investigation of the two-dimensional (i.e. longitudinal and vertical) convective-diffusion processes in an idealized laboratory estuary. The estuary is idealized to obtain steady-state salinity and velocity distributions. The mixing effect of tidal motion is produced by homogeneous turbulence generated by vertically oscillating screens. A fresh water inflow at one end and the introduction of saline water near the other end produces an estuarine salinity intrusion condition. The cyclic convection motion of the tide is not reproduced. The investigation was conducted in three phases which are outlined below. (1) The need for an accurate determination of the salt concentration distribution led to the development of a highly sensitive conductivity probe suitable for measurement in situ. (2) In order to predict the vertical diffusion coefficient from a knowledge of the turbulence intensity, a vertical column was built, and the diffusion coefficient was determined from measurements of the one-dimensional, time dependent, non-convective diffusion process. The horizontal diffusion coefficient is known from previous studies. (3) The horizontal and vertical distribution of salinity was measured in a long, horizontal flume. With an assumption as to the distribution of vertical velocity component, the longitudinal velocity profile was determined. The local value of the bottom velocity was found to correlate with the local, densimetric Frounde Number. The discussion of the experimental investigation concludes with some speculations on the engineering applications of the results.
