This document discusses the complex interactions between climate change, land use change, and their effects on water resources and aquatic ecosystems. It notes that as the climate warms and becomes wetter in New England, precipitation and evapotranspiration patterns will be altered, impacting water availability and streamflow. Increased development leads to higher peak flows and lower base flows in streams due to changes in infiltration and groundwater recharge. Forested watersheds help sustain streamflow during dry periods through subsurface water storage and release. The interactions between climate, land use, and hydrologic processes present challenging questions regarding their relative impacts on water systems over time.
