Many interior drainage systems are patented and recognized by Building Officials and Code Administrators(BOCA) as being effective in controlling basement water. A common system for draining water that has penetrated a basement involves creating a channel around the perimeter of the basement alongside the foundation footers.
A French drain [1] (also called a weeping tile, trench drain, filter drain, blind drain, [1] rubble drain, [1] rock drain, [1] drain tile, perimeter drain, land drain, French ditch, sub-surface drain, sub-soil drain, or agricultural drain) is a trench filled with gravel or rock, or both, with or without a perforated pipe that redirects surface ...
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, [1] made up of a succession of elevated features, such as ridges and hills.
In civil engineering, the invert level is the base interior level of a pipe, trench or tunnel; it can be considered the "floor" level. [1] The invert is an important datum for determining the functioning or flowline of a piping system. For example, the invert of a street sewer connection could affect the feasibility of adding a toilet in the ...
Drainage. High-density polyethylene pipe installation in a storm drain project, Mexico. Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess water. The internal drainage of most agricultural soils can prevent severe waterlogging (anaerobic conditions that harm root growth), but many ...
A drainage equation is an equation describing the relation between depth and spacing of parallel subsurface drains, depth of the watertable, depth and hydraulic conductivity of the soils. It is used in drainage design. Parameters in Hooghoudt's drainage equation. A well known steady-state drainage equation is the Hooghoudt drain spacing equation.
The building envelope or enclosure is all of the elements of the outer shell that maintain a dry, heated, or cooled indoor environment and facilitate its climate control. Building envelope design is a specialized area of architectural and engineering practice that draws from all areas of building science and indoor climate control. [2]
Drainage density is a quantity used to describe physical parameters of a drainage basin. First described by Robert E. Horton, drainage density is defined as the total length of channel in a drainage basin divided by the total area, represented by the following equation: [1] The quantity represents the average length of channel per unit area of ...
