SNAPP TEAM:Water Flow Impact

How can we prioritize source water protection programs that can alleviate the risks of too little or too much water, both today and in the future?

Maintaining reliable freshwater flows is essential for human health and well-being, sustainable economic development, and ecological integrity. This means a minimum amount of water in our rivers and streams during dry seasons, and high flows that are within natural ranges of variation during wet seasons. Floods and droughts are expected to increase with continued shifts in climate. To effectively implement the right actions in the right places in specific watersheds, we need to understand how and where different source water protection actions can contribute to achieving reliable freshwater flows.


OUR APPROACH: To address this issue, this team brings together hydrology and adaptation experts to examine the science, and then work with stakeholder group representatives to interpret the meaning of that science through the lens of those groups: downstream utilities and municipal managers, humanitarian groups working with upstream communities, and aquatic ecologists.

This project is funded in part by the Gordon and Betty Moore Foundation through Grant GBMF7100 to The Nature Conservancy to support the work of the Science for Nature and People Partnership (SNAPP).

Team Status: ONGOING
Team Critical Challenge: Water and Nature
  • Synthesize the best available science on land use and vegetation change impacts on baseflows, flooding, and groundwater recharge, to assess levels of confidence around relationships in different contexts and identify key information gaps.
  • Summarize, in language accessible to key audiences, what the scientific evidence tells us about the potential for different source water activities to generate meaningful impacts related to baseflows, flooding, and groundwater recharge, to enable the design of realistic and effective source water protection programs.
  • Produce ‘principles and guidance’ documentation for helping water funds and other source water protection programs evaluate the potential for land-based adaptation to hydrologically-mediated impacts from land use change and climate change
  • Develop and populate a searchable online portal of key peer-review papers, gray literature, and associated data, to streamline the process of finding and accessing information of relevance to planners’ particular geographic or biophysical contexts
