A flood bypass is a region of land or a large man-made structure that is designed to convey excess flood waters from a river or stream in order to reduce the risk of flooding on the natural river or stream near a key point of interest, such as a city.

The bypass system uses ten pumps located along the jetty. [6] These are two metres beneath the sand. The pumps collect 500,000 cubic metres of sand over the course of a year. [6] The sand, which is naturally moving northwards is pumped via a tunnel under the seaway to South Stradbroke Island, thereby making dredging unnecessary. [6]
The bypass ratio (BPR) of a turbofan engine is the ratio between the mass flow rate of the bypass stream to the mass flow rate entering the core. [1] A 10:1 bypass ratio, for example, means that 10 kg of air passes through the bypass duct for every 1 kg of air passing through the core.
Concentrations of salt in seawater can vary, and splash zones can cause concentrations to increase dramatically from the spray and evaporation. SAE 316 stainless steel is a molybdenum - alloyed steel and the second most common austenitic stainless steel (after grade 304 ).

Brine (or briny water) is a high-concentration solution of salt (typically sodium chloride or calcium chloride) in water.In diverse contexts, brine may refer to the salt solutions ranging from about 3.5% (a typical concentration of seawater, on the lower end of that of solutions used for brining foods) up to about 26% (a typical saturated solution, depending on temperature).
A navigation system is a computing system that aids in navigation. Navigation systems may be entirely on board the vehicle or vessel that the system is controlling (for example, on the ship's bridge) or located elsewhere, making use of radio or other signal transmission to control the vehicle or vessel. In some cases, a combination of these ...
