Assessing of of salinity intrusion on livihoods at Tan Phu Dong and Go Cong Dong districts of Tien Giang province and proposal solutions

Abstract

The situation of saltwater intrusion is becoming more and more serious and complicated, which affects the daily life and production of local people of Tien Giang province in general and Go Cong Dong and Tan Phu Dong districts particularly. However, research on salinity situation in these two districts has not been well studied and still has limitations. Therefore, the research about "Assessing of the current situation of salinity intrusion in Tan Phu Dong and Go Cong Dong districts of Tien Giang province and proposing solutions" is necessary. The research used statistical analysis methods, compared, and simulated the MIKE model, MIKE11- HD and MIKE 11- AD modules: Set up river networks and cross-sections for rivers and tributaries, predicted the risk of salinity intrusion according to the scenarios RCP 4.5 and RCP 8.5 to assess the current situation of salinity intrusion and its impact on Go Cong Dong district and Tan Phu Dong district. After conducting the study "Assessing of the current situation of salinity intrusion in Tan Phu Dong and Go Cong Dong districts of Tien Giang province and proposing solutions", the researchers achieved the following results: (1) the situation of salinity intrusion in both 2 districts became more complicated, salinity intrusion came early, high salinity encroached the fields; (2) Regarding the risk prediction of salinity intrusion: according to the scenarios of RCP 4.5 and RCP 8.5 through the periods of 2030, 2050, 2070, 2100, the salinity level in the studied area tends to increase gradually, the lowest salinity will be from 4 to 6 g/l, the salinity in the whole districts of Tan Phu Dong and Go Cong Dong will exceed 12 g/l in 2100.
