The salinity of 4g/liter could encroach about 75 – 85 km deep into the estuaries of Vam Co Dong and Vam Co Tay rivers; about 48-55km into estuaries of the Mekong River such as Cua Tieu, Cua Dai; and 58-73km into Hàm Luông, Cổ Chiên, Sông Hậu estuaries.
Saline intrusion also affects the water intake of irrigation works in areas about 30-45km from the coast to the mainland from February 18 to the end of March. For areas situated about 45-65 km from the seaside, water intake will be affected during high tides between the 18th and 24th of February, and between the 18th and the 25th of March.
