Abstract
Analytical techniques are developed to describe the mixing between two fluids of different density in a confined aquifer, in which one fluid is introduced to the aquifer by well recharge. The immiscible displacement process in both linear and radial flows is analyzed and the effects of longitudinal and lateral dispersion are included using a boundary layer approximation. The theoretical results demonstrate the effect of hydrodynamic dispersion in retarding gravity segregation due to density differences. The theoretical results are compared with observations of aquifer mixing in linear and radial flow laboratory models. During recharge excellent agreement between the theoretical predictions and experimental results is found and the predicted retarding effects of longitudinal dispersion are verified. During withdrawal some systematic differences between the theory and observation are noted. (Author)
