... Challenges in addressing issues related to groundwater fluxes also arise because researchers are based in many different disciplines including soil science, hydrology, oceanography, geochemistry, geophysics, and wetland ecology. Estimates of recharge/discharge fluxes are needed at many different scales and for many different purposes, including evaluating local risks of landslides, basin-scale sustainable use and management of groundwater resources, management of nuclear waste, and global budgets of water and greenhouse gasses for climate studies.

... The proposed experimental benchmark sites program should also work cooperatively with field programs connected with large-scale hydrocTimatic studies for example, the WCRP Global Energy and Water Experiment (GEWEX) and with studies conducted under the NSF-supported CUAH:SI (Consortium of Universities for the Advancement of Hydrologic Science, Tnc.)

... This would require comprehensive tabulation of regional, continental and global groundwater withdrawals and the extent of the area of wetlands drained during the past century accompanied by evaluation of the effects of the withdrawals and drainage on climate Finding 3 Groundwater measurements are needed across a range of temporal and spatial scales; measurements at one scale are often needed to address questions at another scale. For example, remote sensing techniques provide extensive, spatially complete data sets that hold promise for addressing many of the unresolved questions identified in this report.
