Hi, Replying on the original subject, this gov site has river basin maps. From "flood plain" I first assumed it's about rivers and monsoon flooding; not the sea.
https://mwrra.org/maps/ ----- On the sea level rise matter, a prerequisite dataset for creating the coastal flooding scenarios you guys want, is : sea level rise numbers over time. So, locating that data - simple yearwise numbers probably - might be useful. One can take those and generate all the maps they need using the mentioned elevation data etc. What I've seen so far is interactive simulations where people key in how much they want to raise the levels and then the program gives output. When I found one such site some years ago, I had to set the value sky high to see some real action - but it was totally unrealistic. some links related from a quick web search: https://en.wikipedia.org/wiki/Past_sea_level https://en.wikipedia.org/wiki/Sea_level_rise https://www.e-education.psu.edu/earth107/node/1506 https://coast.noaa.gov/slr/ - this simulator (for USA coasts only) starts at 1ft, which is as per the numbers on the wikipedia article would be multiple centuries in the future. Not sure if humans will still be doing coastal tourism / real estate purchases at that point. We're seeing populations of millions moving between continents in present day - it looks a little too far-fetched to assume the affected peoples covered in these maps won't move at all over the span of centuries.A once in a decade storm generally causes far more sea surge and temporary inundation, so one can expect that peoples and governments involved will have/need arrangements going above and beyond these sea level rise extents. Don't want to be rude, but I'm seeing a gap between the buzz and reality here. And since this topic has been going around for over 2 decades now or more, it would be great to see a comparison between then-projected sea level rise versus actual sea level rise, to catch if projection models have under/over estimated anything and make corrections. -- Cheers, Nikhil VJ https://nikhilvj.co.in On Tue, Mar 1, 2022 at 2:12 AM Supriya Krishnan <supriya.k...@gmail.com> wrote: > @Archi and @Parth > I am also working on urban planning and climate change. > I am looking for sea level rise maps (as a GIS) for the Mumbai > metropolitan region coast.
