Description :
Debris flow frequency and magnitude were determined for 33 basins in southwest British Columbia. Basins are divided into 2 groups using multivariate discriminant analysis : transport-limited basins and weathering limited-basins. Having classified the basins according to sediment supply conditions, multiple regression is used to predict debris flow attributes in each group. An independent test of the regression models with 11 basins yielded generally good results for debris flow magnitude and peak discharge.
