摘要

The objective of Ontario Power Generation's (OPG) Dam Safety Emergency Preparedness and Response Plan (EPRP) program is to minimize the loss of life and property damage in areas that could be affected by dam failure. A key component of the plan is to develop flood inundation maps showing the potential limits of flood conditions prior to and after dam breach. This paper presents an approach that OPG has adopted, utilizing state of the art technology, to automate the production of inundation maps. Mapping software was developed to produce 3-D watershed surface models, generate river valley cross-sectional profiles, and delineate flood inundation limits on digital base maps. The benefit of this software not only increases the mapping accuracy but also significantly reduces costs in comparison to the traditional method of manually superimposing flood inundation limits on topographic maps. The paper describes OPG's experience with the introduction of this software as well as some recommended improvements.
