Drainage Wells in Leaky Water-Table Aquifers
Flow formulas are found for a well draining a water-table aquifer that overlies a semipervious layer through which leakage takes place from or into an underlying permeable strata in which the hydraulic head remains uniform. The leaky water-table aquifer is replenished by vertical percolation due to excess irrigation or leaching or both. A function depending on two parameters is tabulated in order to simplify calculations leading to the determination of the appropriate well discharge and spacing. An expression for the time required to lower the water table to a new desirable elevation is also obtained.
