Rivers and Streams: Multi-scale Understanding and Tools

Session Organizers: Nick Jones, Stephanie Melles
Date: January 5, 8:30 – 10:30 
Location: Salon E

Summary Information

Watersheds are composed of hierarchically nested branched directional networks that present challenges in studying their function and variation at different spatial scales. Likewise, resource managers face an overwhelming complexity of information that requires understandable solutions. This symposium will focus on understanding processes across scales and types of streams to reduce complexity and provide tools for research and management.
