Concrete check dams in Austria A steel check dam A common application of check dams is in bioswales, which are artificial drainage channels that are designed to remove silt and pollution from runoff. A check dam is a small, sometimes temporary, dam constructed across a swale , drainage ditch , or waterway to counteract erosion by reducing water ...
Reinforced earth with gabions supporting a multilane roadway Gabions as X-ray protection during customs inspection. A gabion (from Italian gabbione meaning "big cage"; from Italian gabbia and Latin cavea meaning "cage") is a cage, cylinder or box filled with rocks, concrete, or sometimes sand and soil for use in civil engineering, road building, military applications and landscaping.
Scheduled repairs total around $389,498 USD, and include overall reinforcement of the culverts and concrete wing-walls, overall construction of the masonry works and gabion boxes, and construction of the check dam retain walls. [2] Alongside Jidbali road, the Garowe-Bosaso highway is one of the main paths from the Nugaal to the north. [5] [6]
Chemical sediment control is currently used on some construction sites around the United States and Europe, typically larger sites where there is a high potential for damage to nearby streams. [3] Another active treatment system design uses electrocoagulation to flocculate suspended particles in the stormwater, followed by a filtration stage. [ 4 ]
Sack gabions in Casalecchio di Reno Bridge abutment with gabions. A Maccaferri gabion refers to a type of gabion produced by the Maccaferri family.. In 1893, in Casalecchio di Reno near Bologna, Italy, large quantities of wire mesh Maccaferri sack gabions were used for the first time to repair dams destroyed by a flood of the river Reno.
Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.
A few check dams exist on small upper tributaries of San Juan Creek, mostly inside the Cleveland National Forest. A larger gabion-type dam is located on the middle part of San Juan Creek near the Cañada Gobernadora. Although the dam has silted in and is no longer used for water storage, its roughly 3-to-4-foot (0.91 to 1.22 m) drop still poses ...
Erosion control is the practice of preventing or controlling wind or water erosion in agriculture, land development, coastal areas, river banks and construction. Effective erosion controls handle surface runoff and are important techniques in preventing water pollution , soil loss , wildlife habitat loss and human property loss.
