Drought in the Southern region - Illustrative image (Source: VNA)HCM City (VNA) – Expertshave predicted that the southern region will see reduced drought and salinityand more out-of-season rain in the dry season of 2017, as it is an area affectedby the neutral phase which is a transit stage between El Nino and La Nina.
According to Nguyen Kiet, head ofthe Forecasting Office under the Southern Regional Hydrometeorological Centre,Vietnam and the southern region in particular have experienced the longest ElNino in the history, spanning from late 2014 to early 2016.
In the dry seasons of 2015 and2016, severe salinity and drought caused heavy damage, especially in the MekongDelta.
During the neutral phase,rainfall is high and frequent out-of-season rains occur.
Kiet said that between Januaryand March 2016, the southern region saw no out-of-season rain. However, inJanuary and February of 2017, rains struck from Binh Phuoc to Ca Mai with arainfall of about 100mm.
It is forecast that in March andApril, out-of-season rains may occur in the region, but on a smaller scale andwith less rainfall.
The out-of-season rain isexpected to reduce salinity, especially in Ben Luc area along Vam Co river. Therain also creates water sources for the Mekong Delta region, with water levelsin the Tien and Hau Rivers set to nearly double from the same period 2016.
According to the SouthernRegional Hydrometeorological Centre, in Ho Chi Minh City, the highest salinitylevel recorded in early March in Nha Be station on Dong Dien river was 0.9 gramper litre.
Meanwhile, in the Mekong Deltaregion, the level was 22.9 gram per litre at Ganh Hao River in Ca Mau.
Bui Thanh Giang, Vice GeneralDirector of the Saigon Water Supply Company, held that if salinity became moresevere, the water supply sector of Ho Chi Minh City will work with themanagement board of Dau Tieng and Tri An reservoirs to carry out water pumping plans.
At the same time, Dang Hoa Vinh, headof the water resources under the Ho Chi Minh Institute of Geography Resources,suggested building reservoirs and using the Lang The flood-drainage corridor inCu Chi district as a reservoir.
In the dry season, the reservoirswill serve as water supply resources for Tan Hiep waterwork as well as thecity’s farms and industrial activities.
At the same time, the city can uselakes to store water in case of salinity and drought, he said.-VNA
