The best fit approach for the muskingum coefficients X and k and the computer programs for muskingum method

Abstract EN

The maximum linear correlation coefficient is used to determine the Muskingum coefficients X and K instead of the traditional drawing method.

Two computer programs, coded in Quick-Basic 71, are presented in this research for the application of Muskingum method.

The first program is used to determine the expected outflow hydrograph from a river reach.

The second program is for determining the Muskingum coefficients X and K.

Through two illustrative examples, it is concluded that using the maximum linear correlation coefficient in determining the coefficients X and K is simpler than the traditional drawing method.

Moreover, the outflow hydrograph results from a river reach are closer to the real results.

By the use of the constructed programs in this research, the time is saved and the errors that may occur at any step of calculations are prevented.
