Part of: 50th Anniversary of the Hydraulic Division 1938-1988


The historical development of hydromechanics in the fifty years since the founding of the Hydraulics Division is reviewed. Rouse's 1938 text, Fluid Mechanics for Hydraulic Engineers, provided the intellectual underpinning for the replacement of empirical hydraulics by analytical techniques based on fluid mechanics. Progress in hydromechanics, of interest to Civil Engineers, is traced by discussing a few milestone papers published at the third points of the fifty year period. 1956 is represented by a series of exploratory studies in hydraulics that introduced important concepts of buoyancy and stratified flows. These studies set the stage for research during the following thirty years. 1988 is represented by a series of papers illustrating our ability to solve complex, multi-dimensional problems involving free-surface flows, buoyancy, shear-generated turbulence and biogeochemical transformations.
