Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Interesting -- I would like to learn more about the
water level and topography of the area. Any pointers ?

Now what ?

There's Flood Maps, originally developed to look at sea level rise from global warming...

Though the view of Indian Point

in Buchanan, New York just south of Peekskill
is inconclusive...

From playing with that earlier, I remember that it is not that good outside of coastal ocean areas. I think it simply adds higher water to ocean level, so if you have a river it is upstreams often already higher then the ocean is (thus explaining the water running downstreams). So it is not a realistic simulation of rivers increasing.

Yes indeed, it's a simple mashup that adds a constant to Google's terrain altitudes.

A full hydrological simulation would be a whole other thing. You'd need a full set of USGS data and some fancy modelling tools.

But Irene is currently weakening, and seems unlikely to pick up power again. So it's looking like the damage may not be as bad as everyone hoped for expected.

I have no idea if this means NYC dodged a nuclear bullet. So I'll just mention again that whatever happens is going to be clear proof that windmills are a DFH conspiracy to raise your taxes.

That's all.

Oh - and if Irene doesn't push the water over the walls, it's almost certain some other event will by the end of the century.

That's a different Indian Point, in Maine. The Indian Point power station is on a sand bar in the Hudson river on the east side, in Buchanan. There's nothing secret about it--plenty of places where you can get good photos.

FEMA publishes flood maps for the entire country; here's the one for that area.http://map1.msc.fema.gov/idms/IntraView.cgi?ROT=0&O_X=7044&O_Y=3622&O_ZM=0.077294&O_ SX=1088&O_SY=560&O_DPI=400&O_TH=55896125&O_EN=55874632&O_PG=1&O_MP=1&CT= 0&DI=0&WD=14400&HT=10350&JX=1227&JY=620&MPT=0&MPS=0&ACT=1&KEY=55 895597&ITEM=1&PICK_VIEW_CENTER.x=552&PICK_VIEW_CENTER.y=303&R1=VIN

It's a viewer and might not work right especially over a slow link. Basically it shows the "100 year" flood zone, more properly called the 1% annual recurrence probability event zone. The flood zone doesn't impinge on the nukes.

These maps are made using field data collected over the years by on-site measurements, then calculated using the HEC-HMS and associated hydrological simulation programs.

Normally, flooding is caused by rainwater draining from higher elevations, and while the modeling tools can accommodate the effect of blockages that cause reductions in downstream flow, I don't know if they actually account for upstream flow from a storm surge.

Viewer doesn't work by a simple cut-and-paste of links. Easy to play with here...
