Abstract
An equation is developed for the length of sea water intrusion under conditions of steady‐state flow in unconfined coastal aquifers. A viscous flow model is used to verify the equation for the length of salt water intrusion. Figures are constructed to show the relationship between theoretical curves and experimental data. The experimental results are conclusive in proving the validity of this equation. The equation appears to be valid even when the Dupuit assumptions are no longer valid. It is conjectured that this equation may be rigorously valid in spite of the fact that it is derived on the basis of several simplifying assumptions. The theoretical profiles of the fresh water‐salt water interface reproduce closely the observed profiles. It is observed that salt water moves toward the outlet along the zone of diffusion toward the outflow section. This observation confirms previous flow‐net analysis.
