Water inflow to imperfect wells in the presence of turbulent and laminar filtration modes
Authors:
Abstract
Drilling wells are widely used for pumping water from water-abundant rocks in urban, industrial, transportation and agricultural water supply, drainage of mines and quarries, water control during construction of large hydraulic structures, etc. Under appropriate hydrogeological conditions, such wells are often equipped with high-performance pumps, as a result of which a significant depression funnel is formed around the well in the aquifer. Filtration rates and hydraulic gradients near the water-receiving part of the well, especially with a pressurized aquifer, may exceed the values obeying the linear law of filtration. Then in the zone nearest to the well there is most often a turbulent type of movement, characterized, as is known, by a quadratic relationship between the velocity of groundwater and hydraulic gradient. It occurs more often in fractured rocks, but can also occur in coarse clastic and granular material.
