RAINFALL, RUNOFF AND DRAINAGE

THIS PAPER EXAMINES THOSE ASPECTS OF THE HYDROLOGIC CYCLE WHICH RELATE TO OCCURENCE OF PRECIPITATION, ITS CONVERSION TO RUNOFF, AND THE DISPOSAL OF THAT RUNOFF FROM THE AREA UNDER CONSTRUCTION. THIS INCLUDES A DISCUSSION OF MEANS OF ANALYSIS OF RAINFALL-RUNOFF RECORDS, AND THE LOGICAL EXTENSION OF THAT STUDY INTO THE ESTIMATION OF FLOODS FOR AREAS WHERE NO RECORDS ARE AVAILABLE. AS A NECESSARY PART OF THIS STUDY, CONSIDERATION IS GIVEN TO THE GENERAL CONCEPT OF PROBABILITY AND THE SIGNIFICANCE AND DETERMINATION OF DESIGN RETURN PERIODS, PARTICULARLY WITH RELATION TO THE DESIGN LIFE OF THE PROPOSED FACILITIES. FOLLOWING THIS, THE HYDRAULIC FEATURES OF THE DRAINAGE ROUTES ARE CONSIDERED, WITH INDICATIONS OF THE MOST SIGNIFICANT ASPECTS OF HYDRAULIC DESIGN THAT MUST BE INVESTIGATED. FINALLY, THE PROBLEM OF FLOODWATER DISCHARGE INTO TIDAL AREAS IS CONSIDERED, AND A MEANS INDICATED BY WHICH LOGICAL DESIGNS FOR THESE FACILITIES MAY BE PRODUCED. (A)
