Abstract
Three finite element numerical models have been designed in order to study the three - dimensional characteristics of steady state groundwater flow in the neighbourhood of deep gravity wells. These relate to single and multiple wells with different boundary conditions. Particular attention is paid to the flow pattern close to the well where the slope of the free surface is steep and the vertical velocity components generate a surface of seepage. This is of great significance particularly when wells are used for drainage purposes and deep drawdown in the well is expected.
The Galerkin finite element approach is adopted in the model formulation because of its greater flexibility in handling free surface groundwater flow problems. The results are presented graphically in chart form suitable for practical use and are compared with results that can be obtained using non - numerical methods. An illustration is given which shows how the results can be applied to design a cost effective system of deep wells in the Wadi El - Natrun area, Egypt.
