High tides in rivers have inundated many areas in Vietnam's southern localities over the past three days, with the tides reaching a record high of 2.23 metres in Can Tho city on Wednesday, said the Can Tho Climate Change Coordination Office.

The tide in Can Tho was 2.23 metres on Wednesday, the highest-ever level in the locality, the office said, noting that, the previous record of 2.15 metres was made in 2011.

On Monday, the high tide broke a dyke in Cai Khe ward, Ninh Kieu district, Can Tho city, so water from the Hau River flooded many houses and orchards adjacent to the river.

On Tuesday, in Ho Chi Minh City, the tide on the Saigon River was at 1.68 metres, inundating some streets in districts 4 and 7, said Vietnam's Southern Regional Hydro-meteorological Centre.

On Monday and Tuesday, high tides broke many dyke sections in some communes of southern Vinh Long province, along the Tien and Co Chien rivers, flooding hundreds of hectares of orchards, the provincial authorities said, on Wednesday.

Local forces are reinforcing dykes in areas hit by flood waters, caused by high tides.

The high tides are seasonal, but the floods have been intensified by ground sinking and inadequate drainage systems, amid rapid urbanisation, according to local experts.
