Thesis (M.Eng.) - Asian Institute of Technology, 1975 The purpose of this study is to analyze the streamflow record of the Mekong River· and to establish an adequate data.-generation model for the synthesis of monthly flow time series. The streainflow data at Vientiane station on the Meko.ng River was chosen for this purpose.· The historical record was assumed trend free and power spectrum analysis was applied to detect the significant periods of the streainflow time series. Since there is no more than one year periodicity of significance, the monthly flows in each calendar month were assumed to be independently distributed following three types of probability distribution. Three data-generation models were constructed based on this assumption, which neglected serial correlations between consecutive monthly flows. The generated monthly flow series were investigated using the capacity requirements as criteria. The Thomas-Fiering generation model, which incorporated serial correlation between consecutive monthly flows, was also used for comparison purpose, The result showed that for water supply purpose, for most practical range of assumed water demands, the normal distribution model and Thomas-Fiering model gave more consistent result with the historical record than the other two models. For flood control purpose, for practical range of assumed flood cut levels, the three probabilistic models gave more consistent results with the historical record than the Thomas-Fiering model. The inadequacy of using capacity requirements as criteria for assessing the generated streamflow series, was shown in this study to be due to the somewhat similar results obtained for the different models, Hydraulics Okamoto, Masami, Chairperson Nir, Zeev, Examination Committee Suphat Vongvisessomja, Examination Committee Asian Institute of Technology.
