STOCHASTIC APPLICATION OF THE LOW-WATER P HENOMENON

The volume and duration of low-flow events in river channels are impor tant characteristics for water management and the design of hydraulic structures. These extreme low-flow characteristics were studied separa tely, as identically distributed random variables, on a time interval of I year. A statistical analysis was performed on the low-flow data s eries of Lepreau River, station 01AQ001 (New-Brunswick, Canada). The o bserved characteristics were compared with the theoretical results usi ng the Kolmogorov-Smirnov and (or) chi(2) tests. It was generally conc luded that the proposed model adequately fits the low-water phenomenon .
