PRESSURE CHANGES AT STORM DRAIN JUNCTIONS

A DISCUSSION IS PRESENTED OF THE RESULTS OF A TEST PROGRAM CONCERNING THE HYDRAULIC BEHAVIOR OF OPEN JUNCTIONS. DATA AND METHODS ARE PRESENTED OF THE HYDRAULIC DESIGN OF THE STRUCTURES. THE EFFECTS OF OPEN JUNCTIONS ARE ANALYZED ON THE MAGNITUDE OF PRESSURE CHANGES IN STORM DRAIN SYSTEMS FLOWING FULL. RECTANGULAR BOXES SERVED AS OUTLETS FOR SURFACE FLOW ALONE AND AS COMBINATION INLETS. PIPE JUNCTIONS WERE STUDIED. SQUARE AND ROUND MANHOLES WERE INVESTIGATED. SEVERAL MEASURES WERE EVOLVED TO REDUCE PRESSURE LOSSES FOR JUNCTION TYPES OTHERWISE CHARACTERIZED BY ESPECIALLY LARGE LOSSES. A CONCLUDING SECTION PRESENTS METHODS FOR THE DESIGN OF INLETS AND JUNCTIONS IN STORM DRAIN SYSTEMS FLOWING FULL, TOGETHER WITH ILLUSTRATIVE EXAMPLES.
