A flood is an overflow of water that submerges land which is usually dry. The European Union (EU) Floods Directive defines a flood as a covering by water of land not normally covered by water. In the sense of “flowing water,” the word may also be applied to the inflow of the tide. Flooding may occur as an overflow of water from water bodies, such as a river or lake, in which the water overtops or breaks levees, resulting in some of that water escaping its usual boundaries, or it may occur due to an accumulation of rainwater on saturated ground in an areal flood. While the size of a lake or other body of water will vary with seasonal changes in precipitation and snow melt, these changes in size are unlikely to be considered significant unless they flood property or drown domestic animals.

Updates in Hydraulic and Hydrologic Modeling Software

Updates in Hydraulic and Hydrologic Modeling Software

Developers of hydraulic and hydrologic modeling software have recently unveiled exciting new program updates and products to increase the efficiency and effectiveness. Dramatic decreases in model run times, thoughtful assembly of multiple information sources, and greater flexibility within hydrologic connectivity options demonstrate just a few ways these changes have improved

EPA Announces Winners of the Fifth Annual Campus RainWorks Challenge

WASHINGTON—The U.S. Environmental Protection Agency (EPA) today announced the winners of its fifth annual Campus RainWorks Challenge, a national college competition to engage the next generation to design solutions for stormwater pollution using green infrastructure. Student teams proposed designs that help aid innovative problem solving for their campus and community.

CULTEC
CULTEC’s Contactor and Recharger chambers may be installed in a trench configuration along roadsides as an alternative to swales. Not only is an underground stormwater solution easier to maintain, it is also aesthetically more pleasing than traditional swales. The subsurface installation eliminates a potential trash collection site and exposed ponding—which

Getting a Grip on Sea Level Rise

Getting a Grip on Sea Level Rise

Climate change, sea level rise, failing infrastructure, and challenged ­budgets are a recipe for disaster in the truest sense. However, while the fact of sea level rise is scientifically undisputed, it is a slow-moving disaster. No one will wake up and find Miami or New York suddenly under water. Yet,

Safe Conveyance of Rare Storm Events

Two people were swept downstream and died during a catastrophic flash flood that struck Ellicott City, MD, on the evening of July 30, 2016. The infrastructure designed to carry stream flow and storm runoff along Tiber Run, which runs through the historic district, was unable to meet the demands of

A Critical Role

A Critical Role

When it comes to moving water efficiently, pumps and valves play a critical role. Some efficiency concerns focus on the wastewater utility sector, where “the EPA state revolving funds are going to fixing failing existing sewers—not so much extending into new service areas as much as they have been, but

What Do We Know, and When Did We Know It?

Those of us who live near the coast (that’s about 39% of the US population) or who in some way depend on products that come from the ocean or are delivered via ports (that’s just about all of us) have a stake in what happens with sea level rise. The
