Welcome to the Bay of Fundy MCCAP Workshop
![Page 2: Welcome to the Bay of Fundy MCCAP Workshop. 1.What question about your MCCAP do you most want to gain clarity about today? 2. What municipal decisions.](https://reader036.fdocuments.in/reader036/viewer/2022062515/56649cf85503460f949c913f/html5/thumbnails/2.jpg)
1. What question about your MCCAP do you most want to gain clarity about today?
2. What municipal decisions are you currently making that will be affected by changes in climate?

Workshop premised on . . .
•Climate change may exacerbate considerable geological risk for future development
•We can mitigate some of that risk

Assessing Geological Hazards 4 of 30
. . . to develop a methodology to incorporate geology into the land use planning process
Geohazards are events caused by geological features and processes that present severe threats to humans, property and the natural and built environment.

Geohazards?

Assessing Geological Hazards 4 of 30
. . . to develop a methodology to incorporate geology into the land use planning process
• coastal flooding and riverine flooding• coastal erosion• land sinking – sinkholes• contamination of water from heavy metals
in soil or acid rock drainage• landslides / slope failure
Geo-events that pose threats

Assessing Geological Hazards 4 of 30
. . . to develop a methodology to incorporate geology into the land use planning process
How do we realistically handle these geohazards in our MCCAPs?

2 climate drivers
1.Sea level rise
2.Changes in precipitation
![Page 9: Welcome to the Bay of Fundy MCCAP Workshop. 1.What question about your MCCAP do you most want to gain clarity about today? 2. What municipal decisions.](https://reader036.fdocuments.in/reader036/viewer/2022062515/56649cf85503460f949c913f/html5/thumbnails/9.jpg)
BIO’s relative sea level rise estimates
0.4-0.9m on 50-year time scale
0.9-1.6 on 100-year time scale

Example from
County of Colchester / Truro

MSC’sSTORM SURGE MODEL
Tell us the impacts you are seeing and at what water levels!
Model based on OUTPUT WINDS
![Page 13: Welcome to the Bay of Fundy MCCAP Workshop. 1.What question about your MCCAP do you most want to gain clarity about today? 2. What municipal decisions.](https://reader036.fdocuments.in/reader036/viewer/2022062515/56649cf85503460f949c913f/html5/thumbnails/13.jpg)
MSC’sSTORM SURGE MODEL
Map display; every hour for 48 hrs out from when model run
Time series graph; point forecast for specific location. Show stage 1, 2 or 3 flooding based on past events.

MSC’sSTORM SURGE MODEL
Does NOT include wave run up
Add 10% to surge levelsif wind facing shoreline . . .
. . . then add tide level
![Page 15: Welcome to the Bay of Fundy MCCAP Workshop. 1.What question about your MCCAP do you most want to gain clarity about today? 2. What municipal decisions.](https://reader036.fdocuments.in/reader036/viewer/2022062515/56649cf85503460f949c913f/html5/thumbnails/15.jpg)
MSC’sSTORM SURGE MODEL
65cm surge predicted at nearly high tide = 2.9m
75-80 cm surge experienced = so 3m + at least another 10cm for wave run up
(more if wind from S/SE)

Observed sea level rise exceeded what the Intergovernmental Panel on Climate Change (IPCC) predicted by 50% for the period 1990–2006.
80% of the rise in sea level between during 2003–2008 is believed to be from ice melt

So use 0.57m
