BOUNDARY-ELEMENT SOLUTION FOR STOCHASTIC GROUNDWATER-FLOW - TEMPORAL WEAKLY STATIONARY PROBLEMS

This paper continues the development of boundary integral equation tec hnique for solving stochastic groundwater flow problems. The case of a quifers under deterministic hydraulic conductivity, but subject to ran dom boundary condition and domain recharge has been investigated in an earlier paper under the assumption of steady state governing equation . In the current paper the governing equation is transient, but the te mporal variation of second-order statistical moments is assumed to be weakly stationary. Several examples of fundamental importance to the u nderstanding of stochastic process are examined both by the analytical and by the numerical (boundary element) techniques.
