In this seminar, five flood management practitioners will provide information and insights on several aspects of this topic, including:
- An overview of flood hazards and history of flood management in BC – Neil Peters),
- The current flood management “administrative model”, (i.e., the roles and responsibilities of various levels of government and other organizations, programs, funding, and new initiatives) – Mitchell Hahn,
- Flood hydrology and climate change – Piotr Kuraś,
- Geographic Information Systems (GIS) applications for flood modelling, hazard and risk mapping – Sarah North, and
- Case studies of BC flood management projects that demonstrate some of the new tools – Monica Mannerström.
The seminar will help participants gain a historical perspective as well as current information about flood management activities in BC. Recent advances in hydrologic analysis, floodplain data management, and hydraulic modelling will be described and illustrated by case studies.
Engineers, planners, and other staff involved with flood management and protection, planning, and development.
Mitchell holds a bachelor’s degree in civil engineering and had 15 years of consulting experience in a broad spectrum of engineering before joining the BC public service. Mitchell began with the Ministry of Forests, Lands, Natural Resource Operations and Rural Development as the Senior Waterworks Engineer and was subsequently appointed the Inspector of Dikes and Head of the Provincial Flood Safety Program in 2016. Mitchell is responsible for envisioning, leading and implementing provincial flood hazard management programs, guidelines, and dike safety along with his staff and eleven appointed Deputy Inspectors.
Mr. Kuraś is a hydrologist with over 15 years of consulting and research experience relating to hydrology, hydrologic modelling, analysis of extremes (peak flows, low flows, precipitation, and Probable Maximum Floods), prediction in ungauged basins, climate change, and field instrumentation and monitoring. Piotr’s specialties include the estimation of extreme (peak) flows and extreme rainfall analysis at hundreds of sites throughout the province for the purposes of infrastructure design (e.g., bridges and hydroelectric dams). Piotr’s recent experience as a lead and reviewing hydrologist include hydrology and climate change studies on the Lillooet River, assessment of drinking water supply for Greater Vancouver, storm water system and upland creek modeling on the North Shore, and forecasting for hydropower projects.
Ms. Mannerström is a Civil Engineer and Principal of NHC with 30 years of consulting experience in hydrology, hydraulics and river engineering. Monica specializes in flood hazard assessments and has managed and provided technical input on a number of floodplain mapping studies for municipal and provincial governments, Fraser Basin Council, First Nations, and BC Hydro. Monica recently managed or acted as technical lead/reviewer for flood studies on the Fraser River from Hope to the Ocean, the Lillooet River, Serpentine and Nicomekl Rivers in City of Surrey, Alouette Rivers in Maple Ridge, Fraser and Nechako Rivers in City of Prince George and numerous other studies dating back to the Federal-Provincial floodplain mapping program in the 1980’s. Monica has prepared case studies for Natural Resources Canada to aid practitioners across the country on incorporating climate change in floodplain mapping and has participated in the preparation of Engineers and Geoscientists of BC's guidelines on flood hazard assessments and flood mapping.
Ms. North is a GIS Analyst and has been with NHC for the past 19 years. She has a B.Sc. in Geography and is a Certified GIS Professional. Sarah works to develop and apply GIS to NHC’s water resource engineering projects, primarily using ArcGIS software. Application areas include flood mapping, flood loss estimation, hydrology, and river morphology. Sarah is responsible for database development, data management and documentation, GIS customization, and manipulation of spatial data for input to numerical hydraulic models. She has managed the GIS work for a number of large projects, including the Lower Mainland Vulnerability Assessment for the Fraser Basin Council.
Mr. Peters has 40 years of experience in water resources engineering, management, and administration with a focus on flood management. Through his work with both the public and private sectors, he has participated in a wide range of projects, including hydrological and hydraulic analyses, river engineering, flood hazard assessment, dike design and operation, and administration of provincial government flood management programs in BC. In 1987, Neil joined the BC Public Service and over the following 28 years he was responsible for implementation of provincial dike safety, river management, flood emergency planning, and floodplain management programs. From 2002 to 2015 he was Head of the Provincial Flood Safety Program and Inspector of Dikes for the BC Ministry of Forests, Lands, Natural Resource Operations and Rural Development (MFLNRORD). He joined NHC in 2016.
