COMPARISON OF MATHEMATICAL VERSUS EXPERIMENTAL FLOOD WAVE ATTENUATION IN PART-FULL PIPES/ FOR SUBCRITICAL SLOPES ONLY/

THIS PRELIMINARY REPORT PRESENTS A COMPARISON OF OBSERVED ATTENUATIONS OF SUB-CRITICAL FLOOD-WAVES IN A PART-FULL PIPE WITH THE COMPUTED RESPONSE TO THE SAME FLOW CONDITIONS USING A NUMERICAL SOLUTION TO THE UNSTEADY FLOW EQUATIONS. THE OBSERVED DATA PRESENTED WERE THESE ON SLOPES OF 0.001 TO 0.004, COLLECTED BY THE DEPARTMENT OF SCIENTIFIC AND INDUSTRIAL RESEARCH, HYDRAULICS RESEARCH STATION, OF WALLINGFORD, BERKSHIRE, ENGLAND, AND WERE TAKEN VERBATIM FROM THEIR REPORT. REPRESENTATIVE PLOTS SHOWING THE COMPARISONS FOR PEAK DEPTH VERSUS BOTH DISTANCE FROM PIPE INLET AND TIME ARE SHOWN. DIFFERENCES BETWEEN COMPUTED AND COMPARED DATA WERE MEASURED AND THOSE DEVIATIONS ARE PRESENTED IN TABLES. NO ATTEMPT IS MADE IN THIS REPORT TO INTERPRET THE DIFFERENCES INCURRED WITH THESE COMPARISONS. /AUTHOR/ REFERENCES' THE ATTENUATION OF FLOOD WAVES IN PART-FULL PIPES, P. ACKERS AND A. J. M.
