| dc.description.abstract | The whole development of Zimbabwe and in particular the efficient water resources planning, requires a study of what the low regime is like. The reasons for variation of the mean runoff throughout the country were investigated. Lack of rainfall, rainfall intensity and soil type were ascertained as primary factors that influence or control the occurrence of low and zero flows. The mean annual runoff, mean annual rainfall, mean minimum flow and rainfall in the wet season, length of zero season, catchment lags etc. were calculated from the available ten years data for the seventy three stations chosen. Curves are presented for estimating mean annual runoff from mean annual rainfall for the catchments considered in the study. A map is presented showing catchment lags in the different hydrological zones. An index based on flow duration curves was developed by which the availability of water for abstraction and sewage dilution could be judged. This showed a marked regional variation. | en_US |
