A mixing action that occurs in some estuaries at high tide due to seawater at the surface moving upstream more quickly than the bottom water from the river, causing the denser surface water to sink to the bottom and displace lighter freshwater, which moves to the surface.

[W P Muellenhoff; Environmental Research Laboratory (Narragansett, R.I.);]. Compilation of EPA Mixing Zone Documents Legal mixing zone (LMZ): Refers to a mixing zone in a regulatory sense (e.g., the dimensions of the zone as the state has defined them) as opposed to the mixing zone that naturally occurs in a stream.

Initial dilutions of four ocean outfalls (the Miami-Central, Miami-North, Hollywood, and Broward outfalls) on the east coast of South Florida were determined from dye and salinity studies. Industry and government have used the Offshore Operators Committee (OOC) mud and cuttings dispersion model (Brandsma and Sauer, a) for years to assess the effects of drilling effluent discharges.

Now, a revised version of the model simulates the dispersion of Cited by: major groups of ocean discharges of municipal waste. (Chapter 1 summarizes the total extent of municipal discharges for the nation.) On the Atlantic coast, there is a major assemblage of ocean discharges from both outfalls and barges into the area known as.

The design and prediction of the environmental impact of sea outfalls are discussed. Design objectives and criteria are presented with the emphasis on environmental hydraulics, although internal hydraulics are also reviewed.

Dispersion from outfalls in coastal areas is discussed and two regions of mixing, the near- and far-field, are defined. A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text.

Environmental standards and their implementation in different countries are reviewed for point source discharges into surface waters. The paper focuses on the analysis of existing mixing zone regulations and recommends procedures to develop and manage mixing zone definitions as required by recent amendments of the ‘combined approach' of the European Community water framework by: Initial Mixing Characteristics of Municipal Ocean Discharges (Vol.

I and II). U.S. Environ-mental Protection Agency, Environmental Research Laboratory, Narragansett, Rhode Island. The total quantity of direct discharges to coastal waters (bays, estuaries, and the open ocean) from municipal and industrial facilities does not tell the whole story.

Coastal systems receive inputs from a variety of other sources. Open-ocean discharges through multiport diffusers are diluted rapidly. The National Academies Press. doi. Kaufman and Adams () tried something similar to describe mixing from coastal power plant discharges. As indicated in Fig.

2, their sources and sinks were distributed along a semicircle surrounding the dilution (and hence the magnitudes of the source and sink flows) and the radius of their semicircle were obtained from output of a surface jet model (Stolzenbach and Harleman ).

The near field mixing of such a jet group in a tidal flow is determined by the merging and interaction of coflowing, oblique-flowing, cross-flowing, and counterflowing jets. Despite numerous studies, a general predictive method for such complex jet groups has not been reported; ocean outfall design is often based on comprehensive physical model.

Just upstream from the discharge point, the stream has an ultimate BOD of mg/L. The deoxygenation constant k d is estimated at /day. (a) Assuming complete and instantaneous mixing, find the ultimate BOD of the mixture of waste and river just %(63). The current Ocean Discharge Criteria regulations consider 10 criteria in evaluating NPDES permits for discharges into marine waters.

These criteria emphasize an assessment of the impact of an ocean discharge both on the biological community in the area of the. Initial Study: Exception to the California Ocean Plan for the Hopkins Marine Station Discharge into the Pacific Grove Area of Special Biological Significance.

The Environmental Protection Agency (EPA) is proposing to approve a temporary modification of the currently-designated Massachusetts Bay Dredged Material Disposal Site (MBDS) pursuant to the Marine Protection, Research, and Sanctuaries Act, as amended (MPRSA).

The purpose of this temporary site. is the combination of in-pipe dilution in the case of co-discharges, and near field mixing.

In addition to the salinity requirement, the discharge should meet toxicity and other requirements in the Ocean Plan at the edge of the mixing zone. Co-discharges with power plant cooling water or domestic effluent can be positively buoyant, i.e.

discharges into the affected ASBS maintain natural ocean water quality. If the initial results of post-storm receiving water quality testing indicate levels higher than the 85th percentile threshold of reference water quality data and the pre-storm receiving water levels, then the Discharger must re-sample the receiving water, pre- and post-storm.

Flow features such as the buoyant jet motion and any surface, bottom or terminal layer interaction also take place.

In the near-field region, outfall designers can usually affect the initial mixing characteristics through appropriate manipulation of design variables. * Information obtained from computer output. 1 Depths should correspond to the depths for which initial mixing computation results are provided by the model.

treatment plant discharges and industrial plant stormwater discharges. There are a total of six wastewater treatment plant (WWTP) discharges within the Christmas Bay watershed. Three are municipal facilities (Danbury, Angleton #1, Angleton #2), two are private mobile home parks (Angle Acres Water Supply Corporation, Orbit Systems, Inc.) and one.

Introduction. Santa Monica Bay, like other coastal regions of southern California, receives contaminant inputs from a variety of sources. These inputs include the discharge of municipal wastewater (Raco-Rands & Steinberger, ) and industrial effluents (Raco-Rands, ), disposal of dredged material, atmospheric deposition (Stolzenbach et al., ), and urban runoff during wet and.

Incorporation of the concept of a “mixing zone” In the discussions with Marine and Coastal Management (MCM) and DWAF in latethe concept of a mixing zone within the harbour basin was introduced and accepted in principle by the authorities.

On the other hand, the waste-water discharges to be discussed herein are relatively passive in their effects on the dyn ami cs of the coastal waters, except in the initial mixing zone.

MIXING PROCESSES When sewage effluent is discharged through a submarine outfall diffuser, it undergoes three stages of turbulent mixing processes.The initial sampling locations are selected based on the definition of surface characteristics of the study area and adjoining outfall locations, as well as the purpose of the project (e.g., environmental cleanup, port maintenance, new construction).

Field surveys need to .Further, EPA regulations state that discharges found to be in compliance with section water quality standards will be presumed to also be in compliance with section ocean discharge criteria.

As such, EPA itself has equated ocean discharge criteria with water quality standards, a fact it emphasized when promulgating rules in
