The Casiquiare river is a distributary of the upper Orinoco flowing southward into the Rio Negro, in Venezuela, South America.

The origin of the Casiquiare, at the River Orinoco, is below the mission of La Esmeralda at, and about above sea level.

The volume of water the Casiquiare captures from the Orinoco is small in comparison to what it accumulates in its course.

This named outflow is the Casiquiare canal, which, as it heads downstream ( southerly ), picks up speed and also accumulates water volume.

The simplest description ( besides the entire area-floodplain ) of the water divide is a " south-bank Orinoco River strip " at the exit point of the Orinoco, also the origin of the Casiquiare canal.

The Casiquiare canal connects the upper Orinoco, 9 miles below the mission of Esmeraldas, with the Rio Negro affluent of the Amazon River near the town of San Carlos.

This trip, which lasted four months and covered of wild and largely uninhabited country, had the important result of establishing the existence of the Casiquiare canal ( a communication between the water-systems of the rivers Orinoco and Amazon ), and of determining the exact position of the bifurcation, as well as documenting the life of several native tribes such as the Maipures and their extinct rivals the Atures ( several words of the latter tribe were transferred to Humboldt by one parrot ).

At low gains, only a small corrective action is applied when errors are detected: the system may be safe and stable, but may be sluggish in response to changing conditions ; errors will remain uncorrected for relatively long periods of time: it is over-damped.

By carefully increasing the gain ( i. e. reducing the width of the PB ) this over-damped and sluggish behavior can be improved until the system is critically damped for this SP temperature.

Apart from sluggish performance to avoid oscillations, another problem with proportional-only control is that power application is always in direct proportion to the error.
