Analyses of design floods for small drainage basins in New Brunswick / by Daniel Caissie, Gabriel Goguen and Nassir El-Jabi. : Fs97-6/3443E-PDF
"Flood frequency plays a key role in the design of hydraulic structures as well as in the management of fisheries and aquatic resources. There are two main approaches used to carry out flood frequency analyses, namely the annual maximum series (AMS) approach and the partial duration series approach (or peak over threshold, POT approach). In this study, both approaches were used to analyse instantaneous design floods for small basins (less than 35 km2) in New Brunswick (NB). Results showed that very few stations are available to analyse small basin floods in NB. In fact, only 9 stations were available to carry out the analysis where 4 stations are active and 5 stations are discontinued. Results showed that both approaches (AMS and POT) were very good in fitting flood data for small basins. Results also showed that the currently used NB Watercourse and Wetland Alteration (WAWA) equation most likely underestimates 100-year instantaneous floods when compared to values calculated in the present study. Design floods calculated from other regional flood equations in NB (i.e., from the literature) do envelop observed data for small basins analysed in this study"--Abstract, page v.
