SYNTHESIS OF THE INLET HYDROGRAPH FROM SMALL PERVIOUS AND COMPINATION PREVIOUS-IMPERVIOUS DRAINAGE AREAS

BASED ON THE ACTUAL RECORDED RAINFALL-RUNOFF DATA ON TWO GAGED AREAS IN BALTIMORE (MONTEBELLO 2 - WITH 92% PERVIOUSNESS AND HAMILTON 2 - WITH 80% PERVIOUSNESS), THE COEFFICIENTS IN HORTON'S INFILTRATION EQUATION FOR EACH OF THESE TWO AREAS WERE DETERMINED BY USING A SIMPLE LINEAR STORAGE RESERVOIR MODEL OF THE RUNOFF PROCESS WITH DOUBLE ROUTING TECHNIQUE SUGGESTED BY HOLTAN AND OVERTON (ASSUMING THESE AREAS AS 100% PERVIOUS). THEN BY APPLYING SCHAAKE'S RUNOFF ROUTING COMPUTER PROGRAM TOGETHER WITH THE THUS DERIVED HORTON'S INFILTRATION EQUATIONS FOR THE PERVIOUS PORTIONS OF THESE DRAINAGE AREAS, THE COMPUTED HYDROGRAPHS CAN CHECK WELL WITH THE ACTUALLY RECORDED HYDROGRAPHS, IF THE RIGHT VALUES OF THE ROUGHNESS COEFFICIENT 'N' FOR THESE PERVIOUS AND IMPERVIOUS SURFACES CAN BE USED. /AUTHOR/
