Abstract
The flood quantiles are obtained for each site by fitting each of the Burr Type-III, the Burr TypeXII, and the GEV distributions to the annual maximum observed streamflow using the method of L-moments. For further details, check our publication in Advances in Water Resources (
https://doi.org/10.1016/j.advwatres.2020.103720).
Purpose
Various flood quantiles, corresponding to the return periods of (5, 10, 25, 50, 100, 200, 500, and 1000)-year, are developed at 1119 sites across Canada. These flood quantiles are obtained by fitting Burr Type-III, Burr Type-XII, and GEV distributions to annual maximum streamflow records. An R package called ‘fitsol’ that we recently developed can be used as a tool for estimating these quantiles. This investigation is related to IMPC work package A6: Improving floodplain mapping in flood sensitive areas.
