Groundwater flow in a sandy tidal beach: 2. Two‐dimensional finite element analysis

Abstract

Two‐dimensional finite element techniques are described that model closely the complicated fluctuations observed in the water table of an ocean beach. The use of triangular elements permits the specification of more realistic boundary conditions than the use of line elements in a one‐dimensional model. Also, results obtained from the two‐dimensional model for the region close to the ocean compare more favorably with field data than results obtained from the one‐dimensional finite element model.
