Abstract:

The paper presents the comparison of simulation results of the overflow operation parameters, obtained using a hydrodynamic and probabilistic model. The probabilistic model used the determined empirical relationships. It was shown that the selected parameters of the overflow operation can be determined based on the maximum 30 minute precipitation value. It was demonstrated that the number of precipitation events included in the simulation, and uncertainty of the estimated coefficients affect the forecast results of the storm overflow operation, and their omission may lead to underestimation of the designed overflow edge. The results of calculations by the probabilistic and hydrodynamic models were compared. Comparable results of simulation of overflow operation were obtained. The empirical relationships presented in the study are of a universal nature and the precipitation data are collected in most municipal units, therefore the discussed probabilistic model can be a valuable tool for assessing the operation of storm overflows.
