1) To understand how vulnerable water resources are in face of climate change; 2) to increase understanding of processes influencing onsite water availability and downstream export and how these might be changing over time and in response to climatic changes; 3) to explore forest and climate interactions with water quality, including nutrients, temperature, sediment from headwaters to downstream users; 4) to examine hydrologic responses to climate change through coupling of field observations, modeling and experimental manipulations; and 5) to communicate these findings to researchers, managers, public and policy makers.
