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.
CULTEC specializes in providing chambers for stormwater management and manufactures chambers that adhere to strict standards. The Recharger 902HD chamber is a 48-inch-tall, ultra-high-capacity chamber that has been designed and tested in accordance with ASTM F2787 “Standard Practice for Structural Design of Thermoplastic Corrugated Wall Stormwater Collection Chambers.” Following rigorous
In recent years, the focus on stormwater mitigation in Surfside Beach, SC, has been on water quality, notes John Adair, public works director.
“The topography along the coast is very flat, so getting the water to go toward the ocean is always a challenge because you might only have very slight

Asset management (AM) is a popular management strategy for maintaining the level of service for water and wastewater systems. These systems have clearly defined services and objectives and have been tested and regulated for much longer than stormwater systems. Compared to wastewater, stormwater less frequently receives direct treatment to remove
The Roman Empire was known for many remarkable engineering achievements, including roads that straddled continents and aqueducts capable of conveying life-sustaining water into ever-growing cities at the heart of the empire. Researchers tracing the history of Roman influence in Great Britain, however, long wondered how one critical, remote outpost in
When perspectives on sea level rise are considered, they might easily take on the glass-half-empty or glass-half-full 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 Liberty submerged
Many agricultural areas of the American West are reliant on groundwater withdrawals—and even more so in the face of drought. But many aquifers have become depleted or overdrafted over the years. And as temperatures rise with climate change and as droughts become more extreme, overdrafts are likely to increase. To
Columbia, SC, sits at a point just north and east of the headwaters of the Congaree River. It is here that the Saluda and the Broad Rivers converge to form the Congaree, which spreads broadly across a wide span of relatively shallow rapids as if designed by nature to accept
