A numerical solution is developed for the analysis of groundwater flow problems using semianalytic time integration procedures and the boundary element method. The secondary reduction method, developed earlier, is an integral part of this computation process. Compared to finite difference procedures, which are commonly used for time integration in boundary element applications, the semianalytic computation yields more efficient and accurate results. The proposed method is tested here for two‐dimensional confined flow applications. Numerical results obtained are verified using analytical procedures that are available in the literature and are compared with other boundary element solutions.
