Projects - Research and Application

FloridaWCA partners are actively proposing and implementing collaborative research and application projects to advance their shared interests in relevant climate data and tools for use in water supply and resource planning. Initial project funding (Project 1 below) from NOAA SARP supports not only the technical research, but also the group building process itself. Often the “coordination” and group building aspects that we believe are critical to collaborative research are the most difficult aspects to fund.

Collaborative proposal development is important to sustaining the learning network and ensuring relevant outputs. Two externally funded projects have been funded by NOAA CPO listed below. Multiple proposals have been developed.

Project 1: Collaborative Development of Public Water Supply Utility Relevant Climate Information for Involvement Operations and Planning

Project Dates: 09/01/2011-8/31/2013 extended to 8/31/2014 (COMPLETE)

The goal of this project is to increase the regional relevance and usability of climate and sea level rise data and tools for the specific needs of water suppliers and resources managers in Florida. Specific objectives are to:

  • Develop a collaborative “Working Group”
  • Identify the appropriate spatio-temporal scales, climatic indices, and events that drive utilities’ decisions
  • Evaluate the practical applicability of current climate data, models, tools at these scales
  • Evaluate the usefulness of these data for minimizing current and future risks associated with climate in decision making processes.

    The goal of this project is to improve the regional relevance of seasonal climate forecasts and increase their usability for multiple water managers in Florida. By increasing this usability, these seasonal forecasts can help to minimize short-term operational risks for water supply as well as ecosystem restoration. The specific objectives of this project are to:

    • Evaluate of the skill of the large-scale NMME seasonal climate predictions using the NMME set of seasonal hindcasts
    • Statistical downscaling of the NMME forecasts to the watershed scale and evaluate the skill of these seasonal predictions over three specific domains: Peace River Manasota Regional Water Supply Authority, Tampa Bay Water and the South Florida Water Management District.
    • Execution of a comparative study across three organizations of the benefits and limitations of using seasonal climate forecasts for their operational needs
