what does gingham mean dredged definition

When originally imported into Europe in the 17th century, gingham was a striped fabric, though now it is distinguished by its checkered pattern. Some sources say that the name came into English via Dutch. The name may originate from Malay genggang 'ajar, separate.' Alternatively, it is speculated that the fabric now known as gingham may have been made at Guingamp, a town in Brittany, France, and that the fabric may be named after the town. It is made of carded, medium or fine yarns. Gingham, also called Vichy check, is a medium-weight balanced plain-woven fabric typically with tartan (plaid), striped, or check duotone patterns, in bright colour and in white made from dyed cotton or cotton-blend yarns. Environmental Protection Agency provides oversight and authorization for the disposal of dredged materials.Type of fabric Gingham cloth with green and white checks Army Corps of Engineers issues permits for the disposal of dredged material the U.S. The disposal of dredged material is managed and carried out by federal, state, and local governments, as well as by private entities such as port authorities. NOAA's Office of Response and Restoration plays a major role in protecting and restoring marine natural resources when environmental damage occurs. These pollutants are introduced to waterways from point sources such as sewer overflows, municipal and industrial discharges, and spills or may be introduced from nonpoint sources such as surface runoff and atmospheric deposition. This environmental dredging is often necessary because sediments in and around cities and industrial areas are frequently contaminated with a variety of pollutants. Since massive ships carry the bulk of the goods imported into the country, dredging plays a vital role in the nation's economy.ĭredging is also performed to reduce the exposure of fish, wildlife, and people to contaminants and to prevent the spread of contaminants to other areas of the water body.

This water depth continues to increase over time as larger and larger ships are deployed. Vessels require a certain amount of water in order to float and not touch bottom. It is a routine necessity in waterways around the world because sedimentation-the natural process of sand and silt washing downstream-gradually fills channels and harbors.ĭredging often is focused on maintaining or increasing the depth of navigation channels, anchorages, or berthing areas to ensure the safe passage of boats and ships.

Dredging is the removal of sediments and debris from the bottom of lakes, rivers, harbors, and other water bodies.
