oa Civil Engineering = Siviele Ingenieurswese - Aids to the appraisal of water resources: sequences of deficient riverflow in some regions of South Africa
Monthly flow records of 38 rivers in Natal, Orange Free State and central and western Transvaal are analysed. Frequency analyses of low-flow sequences of durations 12 to 96 months are performed. The resulting families of annual mass curves are expressed in terms of mean riverflow and generalized on a regional basis. The families of curves are descriptionbed by an empirical formula, the coefficients in which are evaluated for each region.
