Summary

Objectives are quantitative scientific examination of hydrologic processes in the near-stream environment to determine spatial and temporal patterns of stream exchanges with shallow ground, for the purpose of improved understanding of streambed exchanges and resulting impacts on water resources and stream ecology.
