DEVELOPING REGION IN SELF-AERATED FLOWS

THE RESULTS OF TWO INDEPENDENT RESEARCH PROGRAMS ARE COMBINED. THE FIRST INVESTIGATION WAS A STUDY OF THE EFFECT OF AERATION ON THE SPILLWAY FLOW OF A LARGE DAM; THE SECOND, A STUDY OF THE REGION OF DEVELOPING SELF-AERATED FLOW IN A MODEL FLUME. USING THE MODEL DATA AS A BASIS, AN ANALYSIS OF THE DEVELOPING REGION IS PRESENTED, IN WHICH THE AERATED LAYER IS TREATED INDEPENDENTLY OF THE UNDERLYING WATER LAYER AND THE PHYSICAL CONDITIONS UPSTREAM OF THE CRITICAL POINT WHERE AERATION COMMENCES. ON THE BASIS OF A COMPARISON WITH THE PROTOTYPE DATA, A DESIGN METHOD IS PRESENTED FOR A PORTION OF THE DEVELOPING, PARTIALLY-AERATED REGION OF SPILLWAY FLOWS. /ASCE/
