The Stormwater Report

Often containing miles of impervious runways, ubiquitous chemical demands for sanitation and safety purposes, and enormous fleets of vehicles with the potential to drip fuels, airports face unique stormwater management challenges.

Building seawalls around high-traffic coastal areas such as piers, boardwalks, and beachfronts often can provide suitable protection from storm surges, but this added security can entail a social cost. In many cases, seawalls obstruct ocean views. Even worse, while seawalls may confine floodwaters to the beach, they also can restrict convenient ocean access by pedestrians […]

Eastern U.S. coastal communities are particularly sensitive to ice-melt in the Arctic Sea, according to hydrologist David Vallee. Vallee, the Hydrologist-in-Charge at the National Weather Service’s Northeast River Forecast Center (Norton, Massachusetts), was one of three stormwater experts to discuss the effects of climate change on coastal and riverine areas of the eastern U.S. during […]

In today’s urban development landscape, striking a balance between economic prosperity and environmental stewardship is increasingly difficult. If property developers fill wetlands and other natural landforms that accept stormwater runoff, provide habitat for wildlife, and control erosion, the result is often increased flooding and decreased biodiversity. On the other hand, development can stagnate if local […]

When Hurricane Katrina tore across Louisiana in 2005, decimating wide swaths of New Orleans, the region’s vulnerability to flooding from severe storms became a cautionary tale for municipalities around the world. In the years since, local, state, and federal governments have spent more than $20 billion surrounding the city with updated flood control measures, explored […]

Flooding costs billions of dollars in damage annually in the U.S. alone, but finding reliable ways to determine when flooding occurs, predicting the intensity of that flooding, and communicating warnings to the public remains a challenge. Researchers at Northern Arizona University (NAU; Flagstaff) have launched an ambitious project aimed at making floods easier to track. […]

In July, flooding caused by an intense rainstorm in the Halkidiki region of northern Greece led to 7 deaths and more than 100 injuries. The flooding, which occurred in the middle of one of Greece’s traditionally driest months, knocked out water and power in much of the affected area for several weeks. The flood effects […]

In 2010, a smartphone-based campaign that called on motorists to report roadkill sightings in California via text message inspired University of Buffalo (UB; N.Y.) hydrogeologist Chris Lowry to undertake an experiment. If it didn’t require any prior knowledge or specialized equipment besides the small computers we carry in our pockets, could ordinary people help gather […]

In South Carolina, which barely escaped the brunt of Hurricane Irma last summer, municipal stormwater managers are demonstrating that there is no “one-size-fits-all” solution to limit runoff pollution. And as the risks of poorly conceived stormwater management plans heighten with more frequent and more intense precipitation, the state’s big cities and beach towns are taking […]

A record-breaking accumulation of snow on the Sierra Nevada mountains is melting steadily as temperatures continue to warm and the thaw continues. That’s both good and bad news for Nevadans — while snowmelt represents one of the most reliable sources of drinking water for the dry West, this year it could bring up to 2.5 […]
