Tag: stormwater runoff

Surface runoff (also known as overland flow) is the flow of water that occurs when excess stormwater, meltwater, or other sources flows over the earth’s surface. This might occur because soil is saturated to full capacity, because rain arrives more quickly than soil can absorb it, or because impervious areas (roofs and pavement) send their runoff to surrounding soil that cannot absorb all of it. Surface runoff is a major component of the water cycle. It is the primary agent in soil erosion by water.

You might never look at gummy bears in the same way again. This summer, fishing crews all along the West Coast of the US and Canada are finding an abundance of pyrosomes—colonies of jelly-like sea creatures, or zooids—that have been compared, in texture and appearance, to the dense, transparent candy. Typically

In many ways, material recovery facilities (MRFs) are harsher work environments than landfill working faces. During both operations, the protection of human health and the environment are primary concerns. While not exposed to the elements, the management of waste in a confined building has its own hazards. Enclosed facilities that

Integrating Land-Use Changes for Future Stormwater Projects

In early July 2013, 2 inches of rain fell within a 45-minute period at the city-owned Lebanon Municipal Airport in Lebanon, NH. This storm created devastation for the city and the airport, with multiple slope failures and roadway washouts. In all, 3.47 inches of rain fell during the 10-year storm

Foliar Rainfall Retention

Foliar Rainfall Retention

Trees and forest systems play an important role in the water cycle by intercepting rainfall and regulating water flow to the soil for more efficient stormwater infiltration. Traditional urban development practices have reduced the function of these systems by eliminating the vertical structure (tree canopy cover), removing existing ground cover

Catching Up

In the 1940s, two former music hall entertainers, Marcel and Nelly Tilloy, purchased an estate in France’s Rhône ­Valley, and by 1952 they had created Relais and Châteaux, with eight hotels and restaurants between Paris and the French Riviera. Today, the association has more than 520 partners around the world.

Rainwater Harvesting

Rainwater Harvesting

Although various forms of rainwater harvesting have been used for thousands of years, as an organized industry, it is still in its infancy. At present, no national standards are in place regulating its use, although various states and municipalities have begun promulgating laws concerning how rainwater may (or may not)

Deploying Plastic Against Itself

Deploying Plastic Against Itself

The amount of plastic debris in the oceans now amounts to hundreds of millions of tons, much of it concentrated in gyres or patches each the size of a largish US state. Although it doesn’t really go away, plastic does break down into smaller pieces—microplastics—that are easily ingested by birds
