Salt Marshes and Seawalls Work Together to Minimize Flood Damages

Salt marshes — coastal wetlands common to northern parts of the globe that flood and drain with the movement of ocean tides — are prized for their ability to protect coastal communities by shrinking and slowing ocean waves. However, according to a recently published study, contemporary and historical data underscore an even more important function […]

Increasing Dependence on Mountain Meltwater Could Threaten Lowland Agriculture

California’s Central Valley generates an estimated $17 billion in crop sales each year while occupying less than 1% of farmland in the U.S., according to the U.S. Geological Survey (USGS). In many southern stretches of the Central Valley, as much as 50% of water currently used for agricultural irrigation originates from the Sierra Nevada mountains, […]

$4.6 Billion Plan Aims to Limit Storm Surge Risks in South Florida

The “Great Miami Hurricane” struck South Florida in 1926, creating intense wind gusts as fast as 240 km/h (150 mph). High winds carried huge volumes of rain and ocean water inland, leading to water levels as high as 4 m (12 ft) in downtown Miami. The historic storm caused nearly 250 deaths and more than […]

Virtual Experiences Bring Stormwater Outreach to Life

Part of the challenge of achieving financial and social buy-in for flood management projects is that their benefits often only become apparent when flooding does not occur. Without the ability to demonstrate, for example, how investment in flood control by public officials can minimize future disasters or how taking simple mitigation steps can help homeowners […]

New Report Underscores Funding Needs For U.S. Stormwater Sector

As heavy storm events become more frequent and impervious coverage spreads, the gap between current U.S. investment in stormwater management and the level necessary to satisfy Clean Water Act requirements continues to widen. According to the latest estimates from the U.S. Environmental Protection Agency (EPA), bolstering stormwater infrastructure to effective levels will require nearly $70 […]

WEF Stormwater Experts Offer Feedback on 2020 Industrial Stormwater Permit

Although specific protocols for manufacturing, processing, and storage may vary dramatically across industrial facilities in different sectors, human and environmental health require all industrial facilities to keep toxic chemicals and other contaminants out of stormwater runoff. The U.S. Environmental Protection Agency (EPA) Multi-Sector General Permit (MSGP) helps these facilities manage their discharges by providing specific […]

Build an At-Home ‘Storm in a Glass’ to Engage Kids in Stormwater

Effective stormwater management goes beyond utilities and regulatory agencies. Individuals need to participate, too. Helping these stakeholders understand the importance of stormwater and the forces that drive is an effort that can begin at home.  In April, Popular Science featured a simple, 10-minute experiment aimed at helping children better understand precipitation and the importance of stormwater management. The simple demonstration requires only water, food coloring, shaving cream, and common […]

Unique Seawall Design Provides Rain-or-Shine Benefits

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 […]
