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.

Sea Rise

Sea Rise

When perspectives on sea level rise are considered they might easily take on the glass half-empty or glass half-filled analogy. For many, the glass is half empty and spells doom for thriving municipalities, helplessly sinking into the sea—reminiscent of the cinematic moment in which Charlton Heston finds the Statue of

The Doomsday Vault

The Doomsday Vault

You’ve probably heard of the Global Seed Vault, a facility located in the Arctic that houses 500 million seeds collected from around the world. The vault is buried beneath the permafrost, and its purpose is to keep safe a supply of seeds we could use to regenerate our food supplies

Rock Solid

Rock Solid

Rocks probably were humans’ first construction materials, and they still may be one of our most important.

Loose, as riprap, or contained in gabion walls, they’re ideal for preventing erosion along water channels, ­rivers, creeks, lakes, and oceans.

Reducing Coastal Erosion

Reducing Coastal Erosion

There is a saying that the only thing constant in life is change. In the realm of coastal environments, nothing could be more true. The shifting winds, the tides, and rains are what has created the often beautiful vistas of coastal landscape, the diversity of habitats and ecosystems: stones ground

Stabilizing Hillsides and Creek Bottoms

Stabilizing Hillsides and Creek Bottoms

The rolling landscape of Scott County, MN, is rural but not particularly remote. “That area is farm country, and the Minnesota River goes through the entire area. On the top of the bluffs it’s farmland, but at the river, the elevation drops about 200 feet in 800 feet,” says Paul

Safe Conveyance of Rare Storm Events

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

Stopping a Sinkhole to Save an Alabama Highway

Stopping a Sinkhole to Save an Alabama Highway

With flooding, sinkholes, danger, and suspense, this story may resemble the latest Hollywood adventure film. However, it is the real-life saga of a stormwater pipe collapse on Birmingham, AL’s Highway 280 and a race against time along one of the state’s busiest roadways. Its dramatic narrative rivals any blockbuster action

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
