What I want to do

West Bay was one of the original Mississippi River Delta Restoration projects, if not the first one governments attempted on purpose. It's had a storied opposition and history. For all of that history, it has even more to teach coastal restoration scientists and advocates.

Can the Delta win against the shipping industry? Can Louisiana maintain its integrity and remain the conduit through which the United States dumps its waste and floats its exports?

For hi altittude mapping of emerging islands of the West Bay Diversion, i want to create a photo series of the public photography available.

the screen shots were taken from LA DNR SONRIS GIS at
http://sonris-www.dnr.state.la.us/gis/agsweb/IE/JSViewer/index.html?TemplateID=181

DNR's slippy map is nice, but their Metadata is crud. Some of these data layers are restricted for state of LA use.

Why I'm interested

hopeful story in Louisiana

animated gif of land v water?

dredge and river working together with community input into government restoration

I'm more interested in islands that emerge than islands that are built with the dredge, although it will be very interesting to see which kinds of land last longer in river Floods and Hurricanes, and which plants grow on which islands.

there's also new channels which are built

much more visible in infrared photography

no 2007 no 2010 --water was so full of sediment that it's only a big glare

The Set of Four shows land building, and then a HUGE scouring and re-deposition in step 3, then more scouring and new channels in step 4
