Details

From Shen (2001), the basin is located in the province of Quebec, Canada, and it covers an area of 2690 square km. The data comprises 77 years daily streamflow data from 1919 to 1995 from the HYDAT CD (Environment Canada, 1998). In the basin, winter lasts for about 4 months and precipitation is mainly in the form of snowfall during this period. Spring represents the high flow season due to the contribution of spring snowmelt to river runoff and the spring flood is the annual maximum flood both in flood peak and volume. A typical flood hydrograph with its characteristic values are: flood peak Q, flood volume V, and flood duration D. These flood characteristics are determined by first identifying the flood duration: the dates of start and end of flood runoff using the approach proposed by Yue (2000). Generally, time boundaries of a flood are marked by a rise in stage and discharge from base flow (start of flood runoff) and a return to base flow (end of flood runoff).
