climate change and water working group ccawwg
Climate Change and Water Working Group(CCAWWG)

Provide Scientific Collaborations in Support of Water Management as Climate Changes

Water Supply, Hydropower, Ecosystem Needs, Recreation, Etc.

Surface Water, Groundwater, Ecosystems, Etc.

Flood Control,

Navigation, Hydropower,

Etc..

Climate Change and Variability, Climate and Weather Predictability

Emergency Management, Flood Risk Assessment, Etc.

Water Quality, Air Quality, Etc…

ccawwg approach
CCAWWG Approach
  • Work with the water management community to understand their needs.
  • Foster collaborative efforts across the federal and non-federal scientific community to address their needs in a way that capitalizes on interdisciplinary expertise, shares information, and avoids duplication.
ccawwg activity defining user needs and developing research strategy
CCAWWG Activity:Defining User Needs and Developing Research Strategy
  • Build on the foundation established by USGS Circular 1331
  • Provide collaborative forum to better define the critical capability gaps that face the water management community
  • Facilitate collaborative research and development to address capability gaps
two user needs documents
Two “User Needs” Documents
  • Both address improvement of knowledge, methods and tools
    • “LTdoc” (Assessing Climate Change in Long-Term Water Resources Planning and Management)
    • “STdoc” (Use of Weather and Climate Forecasts in Near Term Federal Water Resources Management)

feedback on additional research areas
Feedback on additional Research Areas
  • Monitoring and Data Collection:
    • Need for understanding adequacy of existing monitoring networks to support water management in a changing climate.
  • Making Decisions Under Uncertainty:
    • Need for understanding the relative merits of various tools/concepts (e.g., adaptive management, robustness, resilience, flexibility) to support water management and development under a changing climate.
    • Need for understanding the compatibility of these tools/concepts with current influences on management (e.g., legislation, appropriations, policy).
