Effect of climate change and human perturbation on groundwater-streamflow interactions: recent and projected trends for North-America

Abstract

"Groundwater is a very important natural resource as it is the main source of freshwater. Although this resource is depleting over the world because of increasing water demands mainly due to irrigation. The main objectives of this research are to point out the areas in North-America that are becoming wetter and drier, and to assess if these changes are mainly due to human or climate influence. Knowing where humans have the most influence on stream interaction changes, enables us to determine which areas we should dedicate more attention and what kind of management policy should be applied there. An analyses was done on the past period and for the future.''
