Ocena możliwości analitycznego opisu hydrogramu wezbrania

A mathematical description of flood hydrograph is desirable in analyses and designs of many hydraulic structures because together with the maximum fl ow in time of tense flow it enables to determine more exactly, the volume of flood and it other parameters. The adequacy of the mathematical description is analyzed in the presented work considering equations in dimensionless equation given in the work of Baptista and Michel (1990), McEnroe (1992), Strupczewski (1964) as well as a typical hydrograph SCS. In the analysis the infl uence of a value of equation parameters on the possibility of “adaptation” of the description to the real hydrograph both in shape and the value of calculated values. The compatibility assessment of the calculated hydrograph with the real one was conducted applying three measures proposed in the work of Sarma at al. (1973). The analysis was conducted for 8 individual hydrographs from drainage areas of a different character.
