Additionally, construction of hydroelectric dams and dyke systems in upper Mekong Delta provinces and cities triggered creating unpredictable consequences such as alteration to natural flows.
The water release from the hydroelectric dams along with heavy rainfall will also cause risk of rising water levels of the Mekong River.
The Mekong Delta has constantly sweltered long- lasting violent rainy spells since the end of June when the rainy and storm season came.
As this reason, the Mekong Delta provinces need to actively deal with the severe weather condition.
According to the Ministry of Natural Resources and Environment, upper Tien and Hau rivers welcomed total three water flows in 2018, increasing 10- 35 percent compared to the annual average and equaling to 2011.
Adjustment of cultivated area for rice-seasonal crops in some upper Mekong Delta provinces as Dong Thap and An Giang as well as lower river of Hau Giang province is considered as a right orientation in the situation of unpredictable flood and flood tide.
Climate changes as well as risks of violent rain, storm, cyclone, lightning, thunderstorm, drought, saltwater influx and tropical depression are predicted more and more complicated. Therefore, it is necessary that the regional hydrology meteorology forecast centers must early issue weather forecast warnings to timely deal with the severe weather.
In order to actively cope with coming flooding season, local authorities are recommended to control and have necessary measures to support flooding- hit- people and minimize damages of properties and people in Mekong Delta.
