Default Rising Sea Levels

Over the next 100 years, how far inland do you think you'll have to go to be safe from destruction due to rising sea levels--worst case scenario?

My chances of being alive in 100 years are pretty slim. If all the ice on the planet melts and the oceans rise a full 30 feet (debatable) My house will be about 1/4 mile closer to the beach.

In OREGON? The coast is very steep and the Willamette Valley is sheltered. Most people in Oregon live 50 miles from the beach, and the coastal towns are usually built high above the beach, so it won't have any effect on anywhere outside a few of the coastal communities.

Why do you care? I guarantee you that you won't be here.

This is funny... most of us won't be here of course but maybe she is concerned about her grandchildren and so on...

I think we should just all get houseboats, yachts, learn to swim, and not worry so much about it. Or maybe as our environment changes over the years we'll all grow gills and webbed feet?


I'm not worried about rising waters so much as I worry about some sort of pandemic... widespread disease and that sort of thing. I do worry about that quite a bit.

Actually, since the Columbia River is tidally influenced upstream past Portland, and there is a small reach of the Willamette that is tidally influenced upstream from the confluence, it's possible that rising sea levels could inundate the low areas along these rivers, including parts of Portland.

I am much more concerned about the condition of our dikes. My father worked for the outfit that designed them, hired about 70 years ago. I remember the Vanport flood. He warned me long ago about New Orleans and said that resources need to be expended to assure that they remain sound.

And yes, there is tidal influence in our water level. Just click on Portland, Vancouver, St. Helens, Longview or Astoria to see it: Advanced Hydrologic Prediction Service: Portland (http://ahps2.wrh.noaa.gov/ahps2/index.php?wfo=pqr - broken link)

In case any of you are wondering, the last time we had flooding .. about 10 years ago, the COE forgot to include a portion of the drainage area in their model. Notice how well it has been managed this year? So far so good.

Before the water gets high enough to worry about, we'll all be dead from eating killer tomatoes.

Most of Oregon's coast has an escarpment along the beaches and shore which is anywhere from 20 to 100 feet in height.
