These provinces run from west to east with a vast network of rivers. Among them, VCD （Vam Co Dong）, VCT （Vam Co Tay） and Soai Rap rivers are the three biggest rivers crossing the province. In recent years, the flows of rivers have changed a lot and saline intrusion has been very complicated. Salt water has intruded deeply into the field. In the 2000s, salt water only reached Tuyen Nhon （Thanh Hoa district）, but now it has reached Vinh Hung district, about 50 km far from Tuyen Nhon. In 2016, the maximum of salinity in Xuan Khanh （Duc Hoa district） in VCD river was 6.8‰ and Tuyen Nhon （Thanh Hoa district） in VCT river was 5.2‰. In the coming years, the situation of salt intrusion is going to happen more unpredictable under effects of global climate change and sea level rise.展开更多
