This procedure meant a delay of at least 20 minutes for the boat travelling upstream, while the ship heading downstream suffered a delay of about 45 minutes as a result of the manoeuvre. The introduction of auxiliary engines enabled chain boats to travel downstream under their own power without using the chain, thus avoiding the need for these ...

The water in this stream forms varying currents as it makes its way downhill. In hydrology, a current in a water body is the flow of water in any one particular direction. The current varies spatially as well as temporally, dependent upon the flow volume of water, stream gradient, and channel geometry.
A body of water, such as a river, canal or lake, is navigable if it is deep, wide and calm enough for a water vessel (e.g. boats) to pass safely. Navigability is also referred to in the broader context of a body of water having sufficient under keel clearance for a vessel. [1]
