A worldwide compilation of observed submarine groundwater discharge (SGD) shows that groundwater seepage from the land to the ocean occurs in many environments along the world's contimental margins. Further, SGD has a significant influence on the environmental condition of many nearshore marine environments and provides a strong motivation for improved assessments. SGD should be paid more attention with regard to water and dissolved material budgets at the local and global scales. However, our review reveals a critical lack of data form coastal zones of almost all parts of the world, especially in South America, Africa and parts of Asia, making a comprehensive compilation incomplete. Indoor modeling investigate has been made to support to establish the modeling by data, methodologies and technologies. Discharging fluids, whether derived from land or composed of re-circulated seawater, will react with sediment components. These reactions may increase substantially the concentrations of nutrients, carbon, and metals in the fluids. We focus on the possible changes in the processes of commixing by different inverse proportions of cubage, temperatures, and pH.Large numbers of data have been gotten from the indoor modeling investigate. We found that the contents of Sulfur, Nitrogen and Phosphorus has relation with pH, which also can be seen between NH4+-N, NO3--N and NO2--N. We can't confirm to the rules by changing temperature, although we found that it influence the pH. The different cubage-modeling consummate explains the mix between SGD and ocean water.
