“…Horizontal wells were first installed in 1927 [235]; however, they were not widely adopted because of the lack of drilling techniques for horizontal wells. Until 1980s, the interest of horizontal wells was reignited with the significant advance of techniques in drilling horizontal wells [236].…”

“…Horizontal (Ranney 1 ) collector wells are widely used for freshwater supply [14]. These systems consist of a central caisson with an interior diameter of 4-8 m and a series of laterals extruding through the walls of the caisson into the aquifer.…”

“…Such facilities may include horizontal wells and radial collector (also referred to as Ranney or star) wells with horizontal arms, which can provide high flow rate. RBF-based drinking water production and horizontal collector wells are used by many cities all over the world such as Warsaw, London, Budapest, and Belgrade (Babac and Babac 2009;Hunt 2003). It is important to know the hydraulics of these complex systems in order to optimize safe and sustainable drinking water production.…”

Riverbank filtration (RBF) is widely used in drinking water production all over the world. The horizontal and radial collector wells are among the most important water production facilities in case of the RBF aquifers. In this study several types of modeling methods are used to analyze the hydraulic conditions of horizontal and radial collector wells. The unsteady and steady-state flow in homogeneous, infinite, semi-infinite, and square-shaped bounded aquifers are investigated. The effect of delayed gravity response is modeled. Three-dimensional analytical and numerical finite-difference (FD) solution techniques are applied during the simulations to provide more reliable calculation results. Comparative analyses are carried out to optimize the wellbore drawdown in FD simulations. This important value is controlled by the local head loss due to the radial flow in vertical plane normal to the axes of screens. The multimesh FD simulation software FLOW is used for infinite and semi-infinite aquifers, while the MODFLOW Revised Multi-Node Well (MNW2) package is applied to the square-shaped aquifers. The late time partitioning (LTP) method is introduced to estimate the late time drawdown in infinite aquifers using semianalytical steadystate drawdown equations considering circular recharge boundaries. The latter value is derived by the semianalytical CW software. The use of results of various mostly analytically based solutions confirmed or improved the accuracy of the approximate numerical solutions. Such analytical support is vital for proper evaluation of the operation of horizontal and radial collector wells.
