Flashing is thin pieces of impervious material installed to prevent the passage of water into a structure from a joint or as part of a weather resistant barrier system. In modern buildings, flashing is intended to decrease water penetration at objects such as chimneys , vent pipes, walls, windows and door openings to make buildings more durable ...
Weatherstripping is the process of sealing openings such as doors, windows, and trunks from the waters above. The term can also refer to the materials used to carry out such sealing processes. The goal of weatherstripping is to prevent rain and water from entering entirely or partially and accomplishes this by either returning or rerouting water.
In road and rail transport, a washout is the result of a natural disaster where the roadbed is eroded away by flowing water, usually as the result of a flood. [1] When a washout destroys a railroad's right-of-way , the track is sometimes left suspended in midair across the newly formed gap, or it dips down into a ditch.
Copper Leader Head at Penn's Quadrangle, Philadelphia 1894 Copper Leader at Shofuso Japanese House and Garden in Philadelphia. The purpose of a leader head is to help transfer excess water from the roof onto downspouts, thus preventing the gutters from overflowing and water washing over the walls, which is a common occurrence in areas susceptible to heavy rain cycles.
Brush gutter guards resemble pipe cleaners and are easy to install. They prevent large debris from clogging gutters, but are less effective at reducing smaller debris. Foam gutter guards are also easy to install. They fit into gutters, so they prevent large objects from obstructing waterflow, but they do not prevent algae and plant growth.
Washout is a characteristic of aircraft wing design which deliberately changes the lift distribution across the span of an aircraft’s wing. The wing is designed so that the angle of incidence is greater at the wing roots and decreases across the span, becoming lowest at the wing tip .
As technology has advanced, more modern drillers have better control of the overall well. Oil well control is the management of the dangerous effects caused by the unexpected release of formation fluid, such as natural gas and/or crude oil, upon surface equipment of oil or gas drilling rigs and escaping into the atmosphere.
If present, the fuse plug is designed to wash out in case of a large flood greater than the discharge capacity of the spillway gates. Although many months may be needed for construction crews to restore the fuse plug and channel after such an operation, the total damage and cost to repair is less than if the main water-retaining structures had ...
