NRC releases report on “Groundwater Fluxes across Interfaces”



Estimates of groundwater recharge and discharge rates are needed at many different scales and for many different purposes. These include such diverse tasks as evaluating landslide risks, managing groundwater resources, locating nuclear waste repositories, and estimating global budgets of water and greenhouse gases. A report summarizing some of the major issues in recharge and discharge, titled “Ground-water Fluxes across Interfaces,” has just been released by the Committee on Hydrologic Science (COHS) of the National Research Council. The report focuses on spatial and temporal variability of recharge and discharge, their scaling relationships in space and time, and interactions of groundwater with climate.
