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?
