Seepage is a noun that refers to the movement of liquid or gas through a porous material. It describes the slow, gradual, and sometimes unnoticeable leakage or permeation of a substance, usually water, into or out of a confined space or substance.
In geology and engineering, seepage commonly refers to the process of water infiltrating through soil, permeable rock, or man-made structures such as dams or retaining walls. This phenomenon occurs due to the pressure difference between areas of higher and lower water levels, resulting in the water gradually seeping through the porous materials. Seepage can have significant consequences, such as soil erosion, structural instability, or the formation of underground flows that may eventually lead to sinkholes or landslides.
In the field of environmental science, seepage is often associated with the contamination of groundwater. Pollutants or toxins from sources such as industrial waste, landfills, or agricultural runoff can seep through the soil and permeable rock layers, eventually reaching and contaminating groundwater reservoirs.
Seepage can also occur in various man-made structures, such as pipes, tanks, or containers that are meant to contain liquids or gases. When there is a defect or damage to these structures, there may be seepage of the contained substance, leading to leaks or the loss of containment.
Overall, seepage refers to the slow and steady movement of fluids or gases through porous materials, and its understanding is crucial in various scientific, engineering, and environmental contexts.
