A joint NASA-Department of Defense study projects that saltwater intrusion will occur by century’s end in 77% of coastal watersheds evaluated, affecting groundwater systems and ecosystems worldwide. The research indicates that 77% of coastal watersheds will experience saltwater intrusion by century’s end due to combined effects of rising seas and changing groundwater recharge patterns. The threat stems from two key factors: sea level rise and alterations in groundwater recharge rates. “Depending on where you are and which one dominates, your management implications might change,” explains Kyra Adams, groundwater scientist at NASA‘s Jet Propulsion Laboratory (JPL) and lead author of the … Continue reading NASA-DOD Study: 77% of Coastal Watersheds to Face Saltwater Intrusion by 2100
