Area 2: Obtain Climate Change Information

For description of this technical area and for the context on how this area fits into the outline of technical areas for incorporating climate change information into water resources assessments, please see our Long-term climate change research activities.

. These areas were featured in discussion of desired versus current capabilities in Addressing Climate Change in Long-Term Water Resources Planning and Management:  User Needs for Improving Tools and Information (pdf 8MB). The result from that discussion are a listing of research needs, or "gaps", under eight technical areas. After compiling this list, a process followed where relative research priorities were assigned to each gap (low, medium and high). The second and third columns of the table indicates priority ratings reflecting pooled views from Reclamation and USACE only, and pooled views from all document reviewers, respectively. The fourth column lists the research activities being supported by Reclamation's Research and Development Office associated with these gaps.
