Geochemical mixing theory suggests that mixing of sea water and calcite-saturated fresh groundwater can result in a solution that is undersaturated with respect to calcite and can lead to significant dissolution of carbonate rocks. The purpose of this study is to investigate the possible mechanisms of the limestone dissolution in Heng-Chun in southwestern Taiwan. The geochemical model EQ3NR/6 and the geochemical transport model HYDROGEOCHEM are used to simulate a series of chemical reactions and solute transport. The input data for the simulation of groundwater quality and hydrogeological parameters were obtained from 24 wells around the Heng-Chun coastal area with reasonably simplified boundary conditions. Results of the simulation suggest that the dissolution process is not controlled by chemical reactions but strongly depends on the groundwater flow. |
