Environmental Hydraulics: Stratified Flows: Stratified Flows

The present lecture notes cover a first course in th~ most common types of stratified flows encountered in Environ­ mental Hydraulics. Most of the flows are buoyancy flows, i.e. currents in which gravity acts on small density differences. Part I presents the basic concepts of stagnant, densit- stratified water, and of flowing non-miscible stratified fluids. The similarity to the (presumed) well-known open channel flow, subject to a reduced gravity, is illustrated. Part II treats the miscibl...
