Removing water from a river will lower the rivers volume and level.
Keeping the water within the river and capturing it within a pipeline maintains the rivers volume and level.
In order to prevent the lowering of the rivers level and volume we need to control the flow of water in the pipeline to that of specific boundary layer near to the pipeline’s intake.
Water in a river does not all flow at the same velocity.
The velocity increases from the rivers bed to a maximum flow in the main stream of a river.
Looking at this two-dimensionally we get the velocity profile from the riverbed to the surface, water moves slower on the bottom of a river and faster on the surface.
The water near to the rivers banks will also move slower than that in the middle of the river.
To mesure the velocity of the bounder layer at the pipelines intake we would use Ultrasonic flow metres measure the velocity of the rivers flow.
Then using a cross-correlation method all particles in the water would be detected at the same time covering the entire measurement beam.
The particle images can then be evaluated by comparing the correlation, to each other, this comparison would repeat within a few milliseconds, giving us a measurement of the flow velocity, from this we could determin the flow profile directly in river.
This mesurment of rivers velocity would be used as the set point, to control the systems pump.
Flow in the pipe would then measured by An electromagnetic flow metre. two field coils are located inside the meters body, with what is termed poll shoes, these coils generate a constant flow over the entire cross-section of the measuring tube.
Then two electrodes are installed at right angles in the wall of the tube..
The Hydrocirc pipe design is polyurethane so there are no short circuits to inter-fear with the conductive liquid.
When water moves through the electric field, the field applies a force to the charged particles, as a result the positive and negatively charged particles in the liquid are separated and collect on the opposite sides of the pipes wall, now an electrical voltage forms that is detected and measured by the two electrodes.
This voltage is liquid proportionable to the flow velocity in the pipeline, with this and together, with the known pipes cross-section area the pipelines flow can then be calculated.
Data from the electromagnetic flow meter, would then be feed back to control unit which automatically adjusts the controlled output of the pump.
By using the set point of the rivers flow and the measured process of water flowing in the pipe line to control the pumping rate, the flow of the pipeline can be matched to that of the rivers boundary layer.
This process is, no more complicated than a proportional, Integral Derivative unit used to control the cruise control of your car.
Now we can capture water in the pipeline and move it through the rivers' estuary, were the pipeline passes the seawater interface of the river into the sea.
Here the rivers water would normally become seawater. But in this case we have saved the water in the pipe from becoming seawater.
During the process, the fresh water has remained within the pipe, while flowing at the same rate as the river.
The pipes volume has displaced the rivers' volume, along the length of the river, so flow rates and the river's volume downstream are not affected.
In matching the rivers flow along the pipeline we have removed no water from the rivers course therefore the rivers' volume and level remains unchanged.
The Pipe line can now travel to the nearest sea shore where water can be collected for treatment for human consumption or pumped to other location, for agricultural or industrial use.
Hydrocirc, s system would also screen and filter the rivers water,
Filtering is aided by a multi layered debris screen designed to prevent ingress of river sediment and organic material.
down stream finer sediment filtering then takes place, within a five way channelled system, containing flow censors and reversible rotating conical filters.
The Hydrocirc concept is a new system enabling greater water extraction with less environmental impact.
