MEAN HIGH WATER


Flooding & Sea Level Rise in the SC Lowcountry





ABOUT
Mean High Water (MHW) is a project documenting the impacts of sea level rise & flooding in and beyond the South Carolina Lowcountry. The title is in reference to the MHW tidal datum defined and maintained by the NOAA Center for Operational Oceanographic Products and Service.

The tides of Charleston Harbor and the Atlantic Ocean are increasingly encroaching into the natural and built environment of Charleston and the Lowcountry. The rate of increase in the number of coastal flood events is alarming. Approximately 45% of all coastal floods observed in Charleston Harbor from 1953 through 2020 have occurred since 2010. An average of 18.8 coastal floods occurred per year in the 1990s. In the 2010s, the annual average was 42.4 coastal floods2, an increase of over 200%.

MHW was started in 2020 by photographer and engineer Jared Bramblett. It is intended to be an evolving and collaborative documentation of the impacts of flooding.

Featured in The Bitter Southerner: Common High Ground

September 14, 2021


Today, the Bitter Southerner published a beautifully written, tragic piece by Spencer George entitled Common High Ground: How Charleston’s Artists are Responding to Climate Change, and I’m honored to have images from my Mean High Water project included throughout the feature. A few months ago, I met Spencer at a coffee shop in Downtown Charleston to discuss the Mean High Water project, my experience as a stormwater engineer, and the flooding challenges we face here in the South Carolina Lowcountry. It’s exciting to see her work published today as part of Better Southerner’s Hell and High Water Series. The timing could not be better - the latest Army Corps report on a surge protection barrier for the Charleston Peninsula was released last Friday, and the public can comment on the plan until October 25th.

Bitter Southerner also just released a Hell and High Water t-shirt, and $5 from every shirt sold will go towards organizations providing relief in the South. Currently, proceeds will go to support those suffering and recovering from the impacts of Hurricane Ida. Check it out in their store!
