US West Coast Coastal Solutions 2021

Coastal Flood Modeling, Prediction and Observations for the U.S. West Coast

March 31, 2021: 10:30am – 2:30pm PDT April 1, 2021: 9:30am – 12:30pm PDT

In recent years, there has been significant progress in U.S. West Coast coastal flood observations, modeling, and forecasting products. Many of these products and observations are now designed in active partnership with local and state partners, and are intended to assist community stakeholders with addressing today’s coastal flood hazards and future flooding, inundation and sea-level rise. This workshop will serve as a forum for assembling the research community working on these various west coast efforts to improve integration and collaboration among these entities to better serve coastal stakeholders. The workshop will also showcase case studies for how these products are evolving to meet a range of coastal stakeholder needs for addressing contemporary and future coastal flood hazards.

Review the current state of coastal flood

observing and modeling capabilities (at multiple time scales) along the West Coast and identify high priority short-term and long-term research tasks that would further advance services that meet stakeholder needs.

Compile and characterize West Coast coastal community solutions projects

that are actively engaging stakeholders at the city, county, and/or state level to co-design and deploy observing and modeling frameworks for coastal flood monitoring, modeling and forecasting needs.

Discuss and synthesize the range of spatial and temporal observations

and modeling/forecasting services needed by stakeholders (e.g., 72-hour flood alerts, real-time data, mid to long-term predictions and scenarios) and engagement platforms.

Establish a roadmap for engaging the stakeholder community

through subsequent workshops or listening sessions to improve integration and collaboration among west coast observing and modeling entities with the aim of enhancing stakeholder services.
