SLIDE 1

General Implications Climate Change

Increase in Temp Changes in watershed runoff Sea level Rise Changes in Precipitation & ET Changes in Snow and Ice Melt Increase in SST duration, extent Changes in Flood depth, duration, extent

Increased Storm surge height and frequency

Increase salt intrusion

SLIDE 2

Climate scenarios – Sea level rise

2030 low - 10 cm high - 25 cm 2050 low - 20 cm high - 40 cm
