Typical layers in a wall system with rainscreen drainage plane. A rainscreen drainage plane is an air gap and the water resistant barrier of a rainscreen. Together they provide a predictable, unobstructed path drainage for liquid moisture to drain from a high point of the wall (where it enters) to a low point of the wall (where it exits) the ...
"Over a mile long reach [of the water channel] adds up to over 1.5 acre of land needed for the two stage drainage ditch design". This acreage of land may already be currently used for other purposes or contains infrastructure and subsurface gas or sewer lines. Thus, the larger the channel is, the more soil, and thus, increased funds required to ...
The drain is characterized by its long length and narrow width, the cross-section of the drain is a function of the maximum flow volume anticipated from the surrounding surface. Channels can range from 1 inch (2.5 cm) to 2 feet (61 cm) in width, while depths can reach up to 4 feet (120 cm).
A constructed swale or bioswale built in a residential area to manage stormwater runoff. A swale is a shady spot, or a sunken or marshy place. [1] In US usage in particular, it is a shallow channel with gently sloping sides.
In the United States, the International Building Code and ASTM International define Exterior Insulation and Finish System (EIFS) as a non-load-bearing exterior wall cladding system that consists of an insulation board attached either adhesively, mechanically, or both, to the substrate; an integrally reinforced base coat; and a textured protective finish coat.
In geotechnical engineering, an interceptor ditch is a small ditch or channel constructed to intercept and drain water to an area where it can be safely discharged. [1] These are used for excavation purposes of limited depth made in a coarse-grained soils. These are constructed around an area to be dewatered.

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.
