| dc.description.abstract | A method is developed for preliminary estimates of the amounts of deficit storage which is formed during a particular low flow event with reference to the natural hydrographs of small-medium catchments in Tanzania. The method is based on the assumption that yield levels are of small proportions of the mean flow and the deficits arise due to seasonal fluctuations only. By using the concept of both the mass curve and behaviour analysis techniques, the series of annual maximum storages on each catchment are obtained and these are then analyzed to ensure that the deficits arise due to seasonal fluctuations only. The relationship between the deficit storage and its frequency of occurrence is calculated for various levels of yield on each catchment through the extreme value type 1 frequency distribution. A simple model is described which expresses this relationship in terms of a few parameters. For use on ungauged catchments, those parameters are related to the physical characteristics of the catchments by multiple linear regressions. The proposed method is illustrated through a design example. General comments and limitations of the proposed method are also provided therein | en_US |
