NOAA water level data - Matlab files

I've downloaded most NOAA water level stations from east coast into Matlab 'mat' files.
They are at data link

State by State SLR reports

Having just got a link to a report by New Hampshire I'm going to put together a list of what might be called official or state government requested reports created by state entities stating SLR rates.

Reports states are doing are often about adapting to SLR so they will or may have a statement about what SLR rate to adapt to.

I'll put all this in a page on this blog as the list builds but here are three that I'm aware of now.

Here are the links. Go to them to make sure you get the correct information.

Delaware
Maryland
New Hampshire
New York Report
Virginia
Florida
Rhode Island
Connecticut
New Jersey


Here are the rise rates stated in the reports  - go to the report linked above to see the basis for their guidance. I use their units.

NOTE - data below needs updating

Delaware (2012)

Three scenarios to 2100
0.5 m (1.6 ft),  1.0 m ( 3.3 ft) and 1.5 m (4.9 ft)

Maryland (2013)

2050 Best 0.4 m(1.4 ft)
2050 Low 0.3 m (0.9 ft)
2050 High 0.7 m (2.1 ft)

2100 Best 1.1 m (3.7 ft)
2100 Low 0.7 m (2.1 ft)
2100 High 1.7 m (5.7 ft)

New Hampshire (2014)

2050 Intermediate Low 0.6 ft, High 1.3 ft, Highest 2.0 ft
2100 Intermediate Low 1.6 ft, High 3.9 ft, Highest 6.60 ft


New York for Lower Hudson Valley & Long Island (2010)

Sea level rise
2020s 2 2 to 5 in

Sea level rise with rapid ice‐melt scenario
2020s 3 5 to 10 in
2050s 19 to 29 in
2080s 41 to 55 in

New Jersey (2019) Please look at the report as this is the most sophisticated analysis that I know of by a state. I'll try to summarize it so it compares to other states. All state planners should look at this analysis.

Virginia (2013)

1.5 feet by 2050

Florida (2010)
0.5 to 1.0 m by 2100 (directly from IPCC)

Conversions 

1 inch = 0.0254 m
1 foot = 0.3048 m

Virginia Beach SLR Adaptation Plan

The City of Virginia Beach and the Hampton Roads Planning District Commission has just released a report titled "Developing a Local Sea Level Rise Adaptation Plan for Virginia Beach". Link to report

The authors are Benjamin J. McFarlane, Hampton Roads Planning District Commission Hampton Roads Planning District Commission
and

Whitney K. McNamara, CFM 723 Woodlake Drive, City of Virginia Beach Planning Department

Flooding maps are included.

They conclude:

Specifically, the City of Virginia Beach will:
1) Use the case studies and other information developed for this report to update existing
city policies;
2) Develop and update outreach materials such as those described in this report as part of
its comprehensive plan update process and ongoing public engagement activities;
3) Use the case studies and other information to help develop a city-wide strategy to
address recurrent flooding and sea level rise.
The Hampton Roads Planning District Commission will:
1) Continue developing and providing policy recommendations related to recurrent
flooding and sea level rise to local governments in Hampton Roads;
2) Use the mapping methodology described in this report to develop regional sea level rise
and storm surge inundation maps to support vulnerability analyses and other technical
services for local governments.

South Florida SLR

Nice publication titled "Water, Water, Everywhere: Sea Level Rise in Miami"

NOAA Tide Gauge Data in Matlab format

I routinely gather hourly water level data from NOAA tide gauge databases.

If you use Matlab  - the are two 'mat' files for each NOAA water level station: one for 'Height' and one for 'Date'. Height in meters and Data in Matlab 'datenum' format.

Here is the link Matlab file links

NOAA CO-OPS Inundation Analysis Tool

NOAA CO-OPS Inundation Analysis Tool

Just saw this nice new tool - http://tidesandcurrents.noaa.gov/inundation/

From the User Guide

The inundation analysis tool provides frequency and duration of inundation statistics above a specified threshold elevation at a given location using observed data from the NOAA Center for Operational Oceanographic Products and Services’ tide stations. The analysis uses six-minute interval time series, with observed times and heights of high waters (tides). Initially developed by the CO-OPS Coastal Oceanographic Applications and Services of Tides and Lakes (COASTAL) Program for the purposes of marsh restoration and planning, the program potentially has broader applications for the coastal engineering and mapping community, including analyzing return frequencies for coastal flooding threshold elevations and/or user specified datum elevations.

Here is a snippet from Sewells Point for early 2014 using MHHW as the reference.

This might be useful for engineers and planners.

Coastal Flooding Perfect Combination

A period of spring tides combined with heavy rains are causing more than nuisance flooding in parts of the mid-Atlantic. Winds switched to the north on the 7th adding to the higher tide and flooding.
