Receiving basin

The term mouth is recommended to be used either in a wide sense as a reduced version and absolute synonym if the term mouth area (in this case, the use of the term river mouth is quite necessary) or in a narrow sense as applied to the point of inflow of any watercourse to another watercourse (tributary mouth) or to a receiving basin (delta branch mouth) as well as to the outlet to the open sea from a semi-enclosed coastal water body (liman mouth, lagoon mouth, estuary mouth). 

It covers a part of the lower reach of a river (mouth reach if the river, including a delta if it is available) and a part of the coastal zone of a receiving basin (nearshore zone of the river mouth) usually with a complex and very changeable hydrographical system inherent in them. This hydrograph-... 

The river mouth area is characterized by accumulative land forms flooded with river water and sometimes with water of the receiving basin, low-lying lands composed of interpenetrating layers of fluvial, marine, and lacustrine deposits. 

River mouth areas on the coasts of oceans, seas, and large lakes are very diverse in structure and hydrological regime. This diversity depends, firstly, on the morphological peculiarities of the lower reach of the river, nearshore zone of the receiving basin and coastal zone as a whole, and, secondly, on peculiarities of the hydrological regime of the river and nearshore zone of the sea. 

The open nearshore zone of the mouth area can be subdivided into wide or narrow, deep or shallow types. The nearshore zone is considered to be deep, when the river streamflow entering the receiving basin separates from the bottom by the seawater layer if this streamflow occupies the whole water column, the nearshore zone is considered to be shallow. 

The proposed morphological classification of river mouth areas also reveals the scheme of river mouth evolution. Only two genetic series of this evolution are possible under the condition of a relatively steady water level in the receiving basin I -> IV and II -> III -> IV. 

The basin A is then gently heated by a small Bunsen flame, which should be carefully protected from side draughts by screens, so that the material in A receives a steady uniform supply of heat. The material vaporises, and the vapour passes up through the holes into the cold funnel C. Here it cools and condenses as fine crystals on the upper surface of the paper B and on the walls of C. When almost the whole of the material in A has vaporised, the heating is stopped and the pure sublimed material collected. In using such an apparatus, it is clearly necessary to adjust the supply of heat so that the crude material in A is being steadily vaporised, while the funnel C does not become more than luke warm. 

Method 1. Arrange the flask containing the reaction mixture for steam distillation as in Fig. II, 40, 1. Proceed with the steam distillation until crystals of p-dibromobenzene appear in the condenser. Change the receiver and continue with the distillation until all the p-dibromobenzeiie has passed over from time to time run out the water from the condenser so that the crystals melt and run down into the receiver. Reject the residue in the flask. Transfer the first distillate to a separatory funnel, wash it with a httle water, and dry the lower layer with a little anhydrous magnesium sulphate or anhydrous calcium chloride filter. Distil slowly from a small distilling flask use a wire gauze or an air bath (Fig. II, 5, 3). Collect the fraction which passes over at 150-170° pour the residue (R), while it is still hot, into a small beaker or porcelain basin for the isolation of p-dibromobenzene. Redistil the fraction of b.p. 150-170° and collect the bromobenzene at 154-157° (3). The yield is 60 g. 

The modem approach to wastewater treatment, protection of the oxygen resources of the receiving waters, requires that all aspects of the problem be addressed, ie, the systems approach. The Ohio River Sanitation Commission (ORSANCO) is an excellent example of basin-wide management dealing with situations that involve several poUtical entities. This approach has been adopted in several other regions. 

During the distillation it is advisable to hold the Bunsen and to heat the rctoit with the bare flame. Under a pressure of 36 min. the acid distils at 245. The pale yellow oil which collects in the receiver is poured out into a basin whilst hot and allowed to cool. The cake of acid is spread on a poious ]jlate and left to drain, when it becomes nearly colourless, and, after one or two crystallisations from small quantities of spirit, is pure.

A reservoir to receive recovered condensate, located at the bottom of a surface condenser. Also any other tank or basin that receives water from flash steam recovery. 

The Willamette River Basin, Oregon serves as an excellent case study of river quality assessment for a number of reasons. First, the Willamette River has been cited internationally as a classic example of how water quality can be restored from a previously poor quality waterway (1-3). Second, excellent background data were available, particularly on hydrology. Third, at the time most of these studies were initiated, the Willamette River was the largest river in the U.S. for which all point-source discharges were receiving secondary wastewater treatment. 

The area, volume and average depth of the ocean basins and some marginal seas are given in Table 10-1. The Pacific Ocean is the largest and contains more than one-half of the Earth s water. It also receives the least river water per area of the major oceans (Table 10-2). Paradoxically it is also the least salty (Table 10-3). The land area of the entire Earth is strongly skewed toward the northern hemisphere.

Am may enter surface water from nuclear power plants sited on the shores. A region of possible concern is the Great Lakes where 35 nuclear facilities are located in the lakes basin. A sample of water from Lake Ontario collected in 1985 and fdtered through a 0.45 pm Millipore filter contained 0.3 mBq 241Am/L (8 fCi/L) (Platford and Joshi 1986). A few water samples from the Savannah River, which received runoff and discharges from the DOE Savannah River Plant, contained 0.05 fCi 241Am/L (2 pBq/L), about the same levels as other American rivers (DOE 1980). 

Some kraft mills use both aerated and nonaerated basins. The stabilization basin, which may precede or follow the aerated stabilization basin, serves as a polishing or holding pond to remove additional organic materials, including biological solids, or to reduce final effluent discharges to receiving waters.
