Abstract

The salinization process was investigated with hydrogeochemical tools to evaluate the new Delta Holocene alluvium, and the zone components are based on the formation of clay, silt, sand and gravel-based. Water level elevation vary between 0.15~1.96 m. The results of the research show that, the groundwater flow rate of approximately 2.7 × 10-7 cm/sec, water level high block locate at the north and central location field area, by the middle of the groundwater flow direction to flow around the beach, in line with the island-type-like distribution of groundwater lens. The purpose of this study was to assess aquifer salinization in the coastal area of the Offshore Industrial Park in Taiwan by using GMS- Modflow & MT3DMS simulation and Calculated salinization concentration. When fresh water was recharged into the shallow aquifers, the ascended groundwater levels reduced chlorine concentrations and remedied aquifer salinization. The results showed that although the sea and fresh water interface solute exchange will impact to reduce the rate of salinization indicators from groundwater desalination of sea far faster rate than close to the sea shore groundwater desalination slower rate; whether it is close to the sea or away from the beach groundwater aroundafter 10 years of rainfall leaching, are dilute to near fresh water, the chloride ion concentration of about 3,000 mg/L.
