Strati?ed ?ow of salt water

 An incompressible steady ?ow of a ?uid, such as a strati?ed ?ow of salt water (as in the isthmus between a fresh body of water and a body of salt water), ?ows in a channel with a sudden change in the height of the channel bottom (this allows for nonzero and v). Assume no variation in the z-direction and write the two equations that result from the continuity equation. (Experiments show that a stagnant region of ?uid exists in front of a sudden increase in the height of the bottom of a channel in a strati?ed ?ow. This phenomenon causes the buildup of smog in Los Angeles when air ?ows toward the city, but substantial smog does not appear in the more densely populated New York City. There are mountains east of Los Angeles but not west of New York.)
