Abstract
Several studies have been done to examine the reasons for the flooding problem in the Salmon River over the past ninety years. The MacLaren Plansearch (1988) study and the follow-up study by EDM (1997) are among the most comprehensive. A major contribution of these studies was the determination of the maximum water surface profile of the Salmon and North Rivers using T = 20-year and T = 100-year return period hydrologic and tidal events. These results were based on a computer program developed by Environment Canada called '1-D'. This research set out to re-examine these findings by first determining whether or not such a complex model, based on the solution of the gradually-varied unsteady flow equations (the St. Venant equations) is needed. The next task involved reproducing the results of '1-D' using another model called SWMM that, if successful, offered important features for modeling the flooding of this system. Other tasks included experimenting with new scenarios and control structures. An important contribution of this research work was to demonstrate the capability, inherent in SWMM, to connect a small stormsewer system to an existing river system, and the study of the effects of doing this for part of the Truro system.
