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

“Developing an integrated coastal research community focused on transforming knowledge into solution actions for climate adaptation and resilience”

Co-Sponsored and Organized by

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.

  • A web-based compilation of West Coast case studies that feature co-designed and deployed coastal flood solutions with stakeholders. 
  • Workshop summary synthesizing the landscape of west coast capabilities and priorities for enhancing these through research and stakeholder application. 
  • A roadmap for engaging with stakeholders for enhanced input on user needs and how well engagement platforms meet their needs.
  • A white paper to inform decision-makers and coastal programs on ways to foster further integration and advancement of capabilities and services to best meet stakeholder needs.

Official Deadline March 20, 2021 -- however all late submissions will be included in workshop outcomes (e.g. posting of project overview videos and contribution to journal publications outcomes).

We invite submission of case studies featuring ongoing projects or efforts where researchers and stakeholders are co-designing and/or deploying observing networks and modeling for coastal flooding solutions along the US West Coast. Please submit your project abstract and a 3-15 min overview recorded presentation (optional but encouraged, can be prepared later after submission) even if you cannot attend the dates of the virtual workshop.
We seek Projects Case Studies that satisfy each of the following characteristics:
  • Research that includes coastal observing networks and/or coastal modeling and prediction for coastal flooding and sea-level rise applications
  • Either ongoing projects both funded or unfunded, and/or terminated in the last 2 years
  • Projects wherein researchers co-design and/or co-deploy with stakeholders at the city/county/state level (federal stakeholders not included for now)
  • Each project case study should be a separate independent submission. If you have more than one case study you wish to contribute please submit separately (multiple submission allowed)
