  2. Depth in a well - Wikipedia

    en.wikipedia.org/wiki/Depth_in_a_well

    Well depth values taken during the drilling operation are referred to as "driller's depth". The "total depth" for the well, core depths and all analysis of core / mud and other materials from the drilling hole are measured in "drillers depth". Well depth values from the wireline loggers operation are referred to as "logger's depth". The loggers ...

    en.wikipedia.org/wiki/Drainage_equation

    the permissible long term average depth of the water table (Dw) on the basis of agricultural drainage criteria; the soil's hydraulic conductivity (Ka and Kb) by measurements; the depth of the bottom of the aquifer (Di) the design drain spacing (L) can be found from the equation in dependence of the drain depth (Dd) and drain radius (r ...

  4. Multilevel groundwater monitoring systems - Wikipedia

    en.wikipedia.org/wiki/Multilevel_groundwater...

    Well clusters consist of a closely spaced group of monitoring wells, each well completed to a different depth in individual boreholes. [1] Well clusters were first used in the 1950s at contaminated sites. [3] Because there is only one well screen in each borehole, there is little risk of vertical connection between zones. [3]

  5. Drawdown (hydrology) - Wikipedia

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

    Static level is the level of water in the well when no water is being removed from the well by pumping. [8] Water table is the upper level of the zone of saturation, an underground surface in which the soil or rock is permanently saturated with water. [9] Well yield is the volume of water per unit time that is produced by the well from pumping. [8]

  6. Hydraulic head - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_head

    In fluid dynamics, head is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid. From Bernoulli's principle, the total energy at a given point in a fluid is the kinetic energy associated with the speed of flow of the fluid, plus energy from static pressure in the fluid, plus energy from the height of the fluid relative to an ...

  8. Retention basin - Wikipedia

    en.wikipedia.org/wiki/Retention_basin

    Storm water is typically channeled to a retention basin through a system of street and/or parking lot storm drains, and a network of drain channels or underground pipes.. The basins are designed to allow relatively large flows of water to enter, but discharges to receiving waters are limited by outlet structures that function only during very large storm eve
