Unlike vulnerable cities and towns along the East Coast of the ., where frequent storms and big waves lead to large variations in day-to-day water levels, tropical coastlines tend to be surrounded by waters with depths that vary less. That means many tropical coastlines were not built to withstand the kinds of routine flooding that will be caused by rising seas.
Stark increases in instances of flooding are projected for Pacific islands, parts of Southeast Asia and coastlines along India, Africa and South America in the years and decades ahead before spreading to engulf nearly the entire tropical region, according to a study led by Sean Vitousek , a researcher at the University of Illinois, Chicago.

Moreover, Galloway observes that when Congress authorizes a USACE project, the money for it is quickly appropriated. But when it comes to appropriating money to remedy any environmental problems resulting from the project, Congress is very slow to allocate funds, an observation Johnson says is “probably true.”

Coastal residents of poor and fast-growing tropical countries face rapid increases in the numbers of once-rare floods they may face as seas rise, with a new statistical analysis offering troubling projections for regions where sea level data is sparse.
Areas damaged by wildfires are known as burn scars and are particularly susceptible to flash floods and debris flows during rainstorms. Rainfall that is normally absorbed by vegetation can run off almost instantly, causing creeks and drainage areas to flood much earlier and with higher magnitude than normal. NSSL supplied real-time close-up radar mobile radar data during rain events in southern California where the local NWS radar beam is blocked by the terrain. The effort was part of the NOAA/USGS demonstration flash flood and debris flow early warning system to help forecasters improve flash flood and debris flow warnings in areas damaged by wildfires.
The researchers combined a statistical technique used to analyze extreme events with models simulating waves, storms, tides and the sea level effects of global warming. They created snapshots of the future flood projections that can be difficult to generate with the limited ocean data available in some places.
Larry Buss, who chairs the USACE National Nonstructural/Flood Proofing Committee, says that when a levee is built in compliance with the requirements of the National Flood Insurance Program, there is no longer any floodplain management in the area behind the levee. All kinds of new development can then occur in the area landward of the levee as if the floodplain no longer exists—when in fact it does.
From the perspective of the USACE, attitudes toward floods have been evolving into what Buss describes as a more “holistic” approach focused on reducing flood risk with the realization that floods will occur. This approach considers all flood risk reduction tools including not just levees but also buyouts and relocations. Buss says many professional flood risk experts believe the nation should consider levees only as a last resort after first considering measures such as buyouts, relocations, elevation, and zoning.
