Nuisance Flooding
Tidal flooding, also known as sunny day flooding or nuisance flooding, is the temporary inundation of low-lying areas, especially streets, during exceptionally high tide events, such as at full and new moons. The highest tides of the year may be known as the king tide, with the month varying by location. These kinds of floods tend not to a high risk to property or human safety, but further stress coastal infrastructure in low lying areas.
This kind of flooding is becoming more common in cities like Charleston, SC and other human-occupied coastal areas as sea level rise associated with climate change and other human-related environmental impacts such as coastal erosion and land subsidence increase the vulnerability of infrastructure.

Coastal Erosion
Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks along the coastline due to the action of waves, currents, tides, wind-driven water, waterborne ice, or other impacts of storms. The landward retreat of the shoreline can be measured and described over a temporal scale of tides, seasons, and other short-term cyclic processes. Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural.
According to the IPCC, sea level rise caused by climate change will increase coastal erosion worldwide, significantly changing the coasts and low lying coastal areas.

River Flooding
One of the three water related threats that regularly impacts South Carolina is flooding along rivers and streams. Other than Louisiana, South Carolina has more waterways feeding the ocean than any other state in the United States. This tremendous water supply combined with a changing climate make events like Hurricane Joaquin in 2015 more and more likely.
As temperatures on earth increase, more water evaporates from oceans, lakes, and waterways, leading to stronger downpours, intensifying the risk and severity of flooding.
