The hydraulics of channels influenced by rotation of the earth

Controlled flow in ordinary channels occurs when the fluid flows through a contraction or over a barrier as eg. a dam. The same effect takes place in very wide channels although the rotation of the earth makes the description far more complicated. This is due to the considerable cross-channel variations of depth and speed that are induced by rotation. Based on observations from the northern Øresund where one may observe a two-layered version of the phenomenon the project aims at giving a physical and mathematical description of the problem.
