Potential Impact of Climate Change Analysis on the Management of Water Resources under Stressed Quantity and Quality Scenarios

Assuring access to high-quality water for its multiple uses is increasingly difficult and relevant, as climate changes are gradually altering the hydrologic cycle and impacting traditional and well-established techniques of water resource management. This manuscript proposes a methodology to assess...
