| Abstract | Daily streamflow models based on the shot noise process have been shown to be able to reproduce the rises and recessions of the daily streamflow hydrograph. It was found that seasonality can be accurately incorporated in the single shot noise models by fitting harmonic functions to the statistics of the data. The single shot noise models can preserve the mean and standard deviation of the daily and monthly data as well as the daily first serial correlation coefficient. The monthly first serial correlation coefficient is not preserved. The use of Weibull distribution instead of the exponential distribution for pulses produces more realistic flood magnitudes and can approximately preserve the skewness of daily data. The double shot noise models can preserve the monthly first serial correlation coefficients in addition to those statistics preserved by the single shot noise models. Three variants of the double shot noise models were investigated. In an attempt to find a possible link between stochastic hydrology and deterministic hydrology the models were modified and some of the driving parameters of the models were estimated directly from data. Reasonable results were obtained. |
