Completed in 1872, the Boyds Corner Dam saw the use of concrete in dam construction for the first time since the Ancient Romans. [ citation needed ] It was put into service in 1873, 78 feet (24 m) high, [ 2 ] making the Boyds Corner Reservoir the City's second oldest, after the New Croton Reservoir .
Different types of fabric used for geosynthetic clay liners. Geosynthetic clay liners (GCLs) are factory manufactured hydraulic barriers consisting of a layer of bentonite or other very low-permeability material supported by geotextiles and/or geomembranes, mechanically held together by needling, stitching, or chemical adhesives. Due to ...
Liners generally have a pore structure that is designed to retain the majority of cement and other small fines. This results (for vertical and inclined surfaces) in the creation of a uniform surface relatively free from blowholes and other surface blemishes when compared to impermeable concrete.
The vertical hard basin drop structure, also called a dissipation wall, is the basic type of drop structure.The vertical hard basin drop consists of a vertical cutoff wall, usually built of concrete, that is usually laid perpendicular to the stream flow, and an impact basin, not unlike a stream pool, to catch the discharged water.

A buttress dam or hollow dam is a dam with a solid, water-tight upstream side that is supported at intervals on the downstream side by a series of buttresses or supports. [1] The dam wall may be straight or curved. Most buttress dams are made of reinforced concrete and are heavy, pushing the dam into the ground.
Pond liners need to be protected from sharp objects (for example, stones) below the liner and from being punctured by any objects in the water body. Protection can be provided with layers of sand, geotextiles (particularly needle-punched nonwovens) and other materials. Pond liners are manufactured in rolls or accordion-folded on pallets.
A landfill liner, or composite liner, is intended to be a low permeable barrier, which is laid down under engineered landfill sites. Until it deteriorates, the liner retards migration of leachate , and its toxic constituents, into underlying aquifers or nearby rivers from causing potentially irreversible contamination of the local waterway and ...
