| Abstract | Many water resources development projects require detailed information on the frequency and magnitude of extreme hydrological conditions such as low and high flows in order to inform various design, planning and management related activities. This study is concerned with low flow conditions and their probabilistic assessment. A low flow condition can be defined as a period, ranging from a day to several days, during which the average streamflow is a minimum for the entire year or for a selected seasonal period. Probabilistic characterization of low flow conditions is important for a number of engineering purposes and to satisfy many societal needs and natural environmental functions, such as the determination of minimum flow requirements downstream of a hydropower plant, design of water storage facilities, quantification of available water resources to inform municipal and industrial usages, management of water quality, determining effluent dilution capacity, assessing the impact of low flows on aquatic ecosystemsand recreational facilities, etc. |
