MotivationClimate Change-Sea level rise-Storm Surges

Canadian First Nations-High risk of pollution in water systems

Walkerton Tragedy-E.Coli bacteria-Seven people died

North Battleford Tragedy-Affected 5800 people

Research Questions and Objectives

1. What are the characteristics of stormwater systems in coastal communities? And how can they be described?2. What are the impacts of more frequent severe coastal storms and storm surges on community stormwater system?3. What are the capacities of community stormwatersystems?4. What are the communities responses to stormwatermanagement planning and strategies?
