THE ESTIMATION OF RUNOFF FROM RAINFALL FOR NEW BRUNSWICK WATERSHEDS

PREDICTION EQUATIONS HAVE BEEN DERIVED FOR FORECASTING RUNOFF VOLUME FOR REGIONS WITHIN THE PROVINCE OF NEW BRUNSWICK. FIVE BASINS WERE SELECTED SO AS TO PROVIDE A REGIONALLY REPRESENTATIVE DISTRIBUTION OVER THE PROVINCE. THE PREDICTION EQUATIONS ARE BASED ON THE STORM RAINFALL, ANTECEDENT PRECIPITATION INDEX, BASE FLOW AND WEEK NUMBER IN WHICH THE STORM OCCURRED. STATISTICAL METHODS WERE USED TO OBTAIN THE LEAST-SQUARES MULTIPLE LINEAR REGRESSION EQUATION, CORRELATION COEFFICIENT, AND THE STANDARD ERROR FOR EACH OF THE TECHNIQUES USED FOR THE WATERSHEDS. THE NUMBER OF STORMS VARIED FROM 8 TO 23 FOR THE BASINS STUDIED. THE STANDARD ERROR OF THE OPTIMUM PREDICTION EQUATIONS FOR RUNOFF RANGED FROM 0.065 INCHES TO 0.212 INCHES AND THE MULTIPLE CORRELATION COEFFICIENT VARIED FROM 0.556 TO 0.963. THE RESULTS OF THE REGRESSION EQUATIONS DEVELOPED FOR ONE BASIN WERE EXTENDED TO A NEIGHBOURING BASIN OF SIMILAR HYDROLOGICAL CHARACTERISTICS BUT WITH ONLY STREAMFLOW RECORDS.
