tide can continue to unloaded a river after the tide has
turned and the level of the water is rising. The moment of
the tide that races on the centre of the river is in excess of
what along the banks, so that the current changes near the
it sustained before ago in the middle one, and, as maritime water is of
greater specific gravity that the coolness, weighing 64 lbs for
cubic foot against 62-1/2 lbs, flows on the bed of the river
to the principle of the tide, while the fresh water on the
surface is working in the opposite direction. After a duration the
water of salt is diffused in the fresh one, so that the density
of the water in a river it decreases as the distance from the sea
increases. Sewage's disposition discharged in a river is
due primarily to the action that mixes that you/he/she is taking place;
since the tide of the tide that is the agent that transports
it more quickly flows rarely than from two to four miles for now,
or, says, twelve to fifteen miles for tide. The extension to that
the suspended matter is brought again back on brook when the
developed current they depend on the quantity of water of highland that
you/he/she has flowed in the part of the tide and superior of the river during the
tide of decline, as this water occupies a certain amount of space,
according to the depth and ampleness of the river, and this way
it prevents again the flowing maritime water to the position that has occupied
on the preceding tide, and bringing with him the matter in
suspension. The movement of permanent seaward of sewage discharged
in the Thames to Barking when there is only a small quantity
of water of highland is to the percentage of approximately a mile a day,
thirty days that you/they take for traveling the trentuns miles to the sea,
while to the mouth of the river the percentage doesn't exceed one-
third of a mile a day.




I CAPITULATE IV.

SELECTION OF PLACE FOR SEWER OF OUTFALL.


The selection of the place for the sewer of maritime outfall is a matter
asking for a more accurate consideration of the many factors
being born on the point and the permanent success of some scheme
