Groundwater injection turns a challenge into an opportunity, say University of Texas researchers

As the saying goes, everything is bigger in Texas — including the water management challenges. Depending on the weather, many Texans routinely deal with either too much or too little water. Over two weeks in 2017, for example, Hurricane Harvey delivered approximately 80 million acre-feet of water to southeastern parts of the state — enough […]

New flood model: Slight increases in rainfall can create major traffic disruptions

Many of the modeling tools that public works agencies, disaster response organizations, and watershed managers use to predict the effects of flooding from major storms do not consider a detail that makes a major difference, according to new research: land elevation. A study published in May in the journal Nature Communications describes a new flood-modeling […]

Report: Green and gray infrastructure work together to enhance service, cut costs

Green infrastructure often requires more frequent upkeep and maintenance than gray infrastructure, generally entails more financial risk, and its effectiveness largely depends on its location. However, a newly released joint report by the World Bank (Washington, D.C.) and the World Resources Institute (WRI; Washington, D.C.) offers a new perspective on how to increase green infrastructure’s […]

U.S. EPA crowns winners of 7th annual Campus RainWorks Challenge

On April 23, the U.S. Environmental Protection Agency (EPA) announced the winners of its 7th annual Campus RainWorks Challenge. The competition tasks college students and faculty nationwide with designing innovative, on-campus stormwater management features. These features need to demonstrate how green infrastructure can mitigate runoff pollution, reduce local flooding, and create new amenities that enhance […]

Volunteers ‘Adopt-a-Drain’ to improve urban stormwater management

According to estimates from the U.S. Bureau of Labor Statistics, about 1 in 4 Americans donate their time each year as volunteers. A growing number of U.S. municipalities are capitalizing on residents’ willingness to pitch in with new volunteer programs that support stormwater management and protect vulnerable waterways. In the Minneapolis–St. Paul (Minn.) metro area, […]

City of Hampton, Va., considers ‘pay-for-success’ funding strategy to enhance resilience

In coastal Hampton, Va., city planners are considering an innovative financing strategy to support new green stormwater infrastructure (GSI) projects. This aims to turn the tide against the severe weather and rising sea levels that have led to increased flooding. The city hopes that by issuing “environmental impact bonds” (EIBs) to investors who seek financial, […]

Denmark demonstrates footprint-free stormwater treatment method

The Danish island of Amager, located just east of Copenhagen, is the testing ground for an innovative stormwater treatment technology called dual porosity filtration (DPF). Early results from a demonstration DPF facility recently constructed on the island’s water-conscious Ørestad district have proven the technology’s ability to treat up to 110 L (30 gal) of urban, […]

USDA: Growing rice helps farmers curb pesticide water quality risks

More than 40,000 different varieties of rice are grown on every continent (except Antarctica), making rice one of the world’s best-loved food crops. And according to new findings from U.S. Department of Agriculture (USDA) researchers, rice crops also have a secondary function: They keep pesticides and other contaminants out of vulnerable waterways.   The problem […]

Climate change and development have intensified flash floods around the world

While average temperatures gradually warm in most parts of the world, resulting in increasingly frequent and intense rainstorms, human expansion and development continue to disrupt the natural landscape’s ability to manage stormwater runoff. According to the first global analysis of how these trends already have affected rates of both precipitation and runoff generation, existing climate […]

‘How high is your river?’ asks CrowdHydrology citizen science project

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 […]
