  2. Seep (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Seep_(hydrology)

    Seep is often used in environmental sciences to define an exfiltration zone (seepage zone) where contaminated water, e.g., from waste dumps, leaves a waste system area. Seeps are often important smaller wildlife water sources, and indicated by lower riparian vegetation.

  3. Groundwater flow - Wikipedia

    en.wikipedia.org/wiki/Groundwater_flow

    Groundwater is water that is found underground in cracks and spaces in the soil, sand and rocks. Where water has filled these spaces is the phreatic (also called) saturated zone. Groundwater is stored in and moves slowly (compared to surface runoff in temperate conditions and watercourses) through layers or zones of soil, sand and rocks: aquifers.

  4. Internal erosion - Wikipedia

    en.wikipedia.org/wiki/Internal_erosion

    Internal erosion is the formation of voids within a soil caused by the removal of material by seepage. [1] It is the second most common cause of failure in levees and one of the leading causes of failures in earth dams, [2] responsible for about half of embankment dam failures. [3]

  5. Canal lining - Wikipedia

    en.wikipedia.org/wiki/Canal_lining

    Canal Lining. Canal lining is the process of reducing seepage loss of irrigation water by adding an impermeable layer to the edges of the trench. Seepage can result in losses of 30 to 50 percent of irrigation water from canals, so adding lining can make irrigation systems more efficient.

  6. Quick condition - Wikipedia

    en.wikipedia.org/wiki/Quick_condition

    The quick condition of soil is the condition when the upward water pressure gradient and water flow reduce the effective stress, i.e., cohesiveness of the soil. Sandy soils may lose their shear strength, and the soil may behave as a fluid‌. Cohesive soils may produce cracks with water seepage. [1] [2] [3] [4]

  7. Subirrigation - Wikipedia

    en.wikipedia.org/wiki/Subirrigation

    Subirrigation also known as seepage irrigation, is a method of irrigation where water is delivered to the plant root zone. The excess may be collected for reuse. The excess may be collected for reuse.

  8. SEEP2D - Wikipedia

    en.wikipedia.org/wiki/SEEP2D

    SEEP2D is a 2D seepage analysis program written by Dr. Fred Tracy of the United States Army Corps of Engineers. The program is used to analyze water seepage, typically through dams and levees or under sheet piles. "The model is internationally known in the engineering community as a model for complicated seepage analysis of dams and levees."

  9. Arthur Casagrande - Wikipedia

    en.wikipedia.org/wiki/Arthur_Casagrande

    The successful soil mechanics and foundation engineering programme at Harvard was hence often credited to Casagrande, and its particular emphasis on laboratory courses and seepage being an integral part of the curriculum would later form the basis of similar courses around the world.
