Comparative evaluation of existing formulas for calculating the flow rate of imperfect wells under confines water conditions
Abstract
A comparative evaluation of the existing formulas for calculating the flow rate of imperfect wells in a confined aquifer is given on the basis of analysis of experimental data obtained during hydrogeological studies in a valley filled with alluvial sediments to which the confined aquifer is confined. Alluvial deposits of the valley are represented mainly by variably grained sands, partly silty and clayey, with gravel, pebbles and single boulders. The total thickness of alluvial formations overlying Tertiary sediments is 40‑42 meters. The upper part of the alluvium is composed of clays and loams up to 13 m thick, which is a confining layer. The head reaches 12.79 m, counting from the roof of the aquifer. The level of this horizon is subject to seasonal fluctuations. The minimum level position is observed in autumn (0.21‑0.95 m below the ground surface), the maximum — in spring, when the water level rises 0.35‑0.83 m above the ground surface, as a result of which some wells flow spontaneously during this period.
