| description | Inputs in a hydrologic system are random characteristics. This randomness is due to precipitation which is random. This randomness of precipitation must be stated with a statistical distribution function. Determining of the probability distribution function will be easy by statistical decision making. In this study, it was determined the best fit probability distribution function of annual precipitation records of Çoruh hydrologic basin. There are 34 raingauge stations distributed fairly uniform in the basin. The best fit of the model investigated both graphically and using Kolmogorov–Smirnov, Chi-Square which are nonparametric tests. While set of the data obtained from some stations have best fitted to normal distribution well, whereas some of them have fitted to lognormal distribution. Some of the rainy stations have fitted to normal distribution, whereas some dry stations have fitted lognormal distribution. |
