Modeling Climate Change Impacts On Coastal Resources With Enhanced Simulation Model Mantra

Accelerated sea level rise (SLR) and precipitation change in response to climate change is well underway, the impacts of which call for appropriate climate action SDG 13. The associated increase in surface seawater inundation and subsurface saltwater intrusion will reduce the availability of fresh g...
