| Popis: | Computing flood discharge of a watershed reliably is of great importance in the design of hydraulic structures. Many empirical methods used for this purpose produce different results. Therefore, methods taking regional climatic conditions and watershed characteristics should be employed. In this study, effectiveness of unitless Turc, Mc Math and Rational methods were investigated through comparing the calculated surface run off from these methods to the directly measured values and also calculated values of an individual methods to those of the others. Using Turc Method, which also includes coefficient suggested for the regional similar sub-basins, water yields were underestimated in comparison to the other methods. Having considered all the calculated and measured results, empirical methods with the new optimised coefficients representing the regional conditions were suggested in order to build reliable hydraulic structures and their spillways. In this way, total cost will be decreased and, on the top of that, the lives and properties will be secured. |
