Abstract:

Saltwater intrusion interface was measured according to 109 water samples and 31 geophysical profiles based on lithology and well logging data. The results show that: it reached a good effect on saltwater intrusion measurement with hydro-chemical and geophysical methods; the present intrusion interface was located along a line around Taitou-Tianliu-Houzhen-Gudi-Liutuan towns; saltwater and freshwater bodies were better showed on the combined pre-3D profiles through high-density method which provided a good idea on further study.

Key words: saltwater intrusion, hydrochemistry, geophysics, Laizhou Bay
