Infiltration is the process by which water on the ground surface enters the soil. It is commonly used in both hydrology and soil sciences. The infiltration capacity is defined as the maximum rate of infiltration. It is most often measured in meters per day but can also be measured in other units of distance over time if necessary. [1] The ...
A percolation trench, also called an infiltration trench, is a type of best management practice (BMP) that is used to manage stormwater runoff, prevent flooding and downstream erosion, and improve water quality in an adjacent river, stream, lake or bay.
An infiltration basin (or recharge basin) is a form of engineered sump [1] or percolation pond [2] that is used to manage stormwater runoff, prevent flooding and downstream erosion, and improve water quality in an adjacent river, stream, lake or bay.
Oil slick created by runoff A percolation trench allows infiltration of stormwater through permeable soils into the groundwater aquifer. An oil-grit separator is designed to capture settleable solids, oil and grease, debris and floatables in runoff from roads and parking lots. Excessive stream bank erosion may cause flooding and property damage.
Infiltration tactics may not be standard in modern combat where training is limited, such as for militia or rushed conscript units, or in desperate attacks where an immediate victory is required. Examples are German Volkssturm formations at the end of World War II, and Japanese banzai attacks of the same period.
There are different methods to determine if a bioswale needs maintenance. Bioswales are benchmarked to meet a specific level of infiltration to determine if maintenance is required. A staff gauge is used to measure the infiltration rate. Soil chemistry testing is also required to determine if the soil has a certain off-level of any pollutant.
Infiltration galleries may be used to supplement a storm sewer, by directing storm runoff from non-road areas.. While the catchbasins under sewer grates work well on swift-flowing surfaces like asphalt and concrete, heavy storm water flow on grass lawns or other open areas will pool in low areas if there is no outlet.
A diagram of a traditional French drain. A French drain [1] (also known by other names including trench drain, blind drain, [1] rubble drain, [1] and rock drain [1]) is a trench filled with gravel or rock, or both, with or without a perforated pipe that redirects surface water and groundwater away from an area.
