Many US communities suffer from routine and severe flooding due to a combination of riverine impacts and old, undersized stormwater collection systems, especially in urban areas. But how many communities have the opportunity to develop detailed hydrologic and hydraulic models of both systems on a watershed scale? How many also use these models to transform their downtown with holistic flood mitigation solutions that truly redefine urban drainage? The City of Fayetteville, NC, had the vision and financial commitment to do just that. This presentation will step through the overall program and vision of the city in establishing and implementing the watershed master plan program. It will discuss the process used to develop, validate, and integrate the 1D and 2D riverine and collection system models, including several project invations to improve efficiency and accuracy. It will also detail the process used and the proposed project developed to cost-effectively provide holistic improvements, mitigate stormwater flooding, and improve livability in downtown Fayetteville. After this session, participants will be able to:
• Identify processes and tools to efficiently integrate 1D and 2D H&H models for the riverine and collection systems.
• Identify strategies to provide holistic solutions to address urban flooding.
• Link collection system and transportation improvements to solve large-scale urban drainage issues and provide greater resiliency.
