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 ...
Infiltration (hydrology), downward movement of water into soil; Infiltration (HVAC), a heating, ventilation, and air conditioning term for air leakage into buildings; Infiltration (medical), the diffusion or accumulation of substances or cells not normal to it or in amounts in excess of the normal
Infiltration in a medical context is the process of cells or substances moving across a barrier, typically a tissue barrier, into a place they are not normally found ...
Infiltration/Inflow (I/I or I&I) is the process of groundwater, or water from sources other than domestic wastewater, entering sanitary sewers. I/I causes dilution in ...
Infiltration is the unintentional or accidental introduction of outside air into a building, typically through cracks in the building envelope and through use of doors for passage. [1] Infiltration is sometimes called air leakage. The leakage of room air out of a building, intentionally or not, is called exfiltration.
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.
Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to channel runoff (or stream flow).It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil.
These soils have a very slow rate of water transmission (final infiltration rate less than 0.05 in (1.3 mm) per hour). Selection of a hydrologic soil group should be done based on measured infiltration rates, soil survey (such as the NRCS Web Soil Survey), or judgement from a qualified soil science or geotechnical professional. The table below ...
