ABSTRACT: The Red-Thai Binh River system is an important water resource to the Northern Delta, serving the development of agriculture, people’s livelihood and
other economic sectors through its upstream reservoirs and a system of water
abstraction works along the rivers. However, due to the impact of climate
change and pressure from socio-economic development, the operation of the
reservoir system according to Decision No. 740/QD-TTg was issued on June 17,
2019 by the Prime Minister of Government promulgating the Red-Thai Binh River
system inter-reservoir operation rules (Operation rules
740) has some shortcomings that need adjustments for higher water use
efficiency, meeting downstream water demand and power generation benefits.
Through the results of water balance
calculation and analysis of economic benefits from water use scenarios,
this research proposed adjustment to the inter-reservoir operation during dry
season in the Red River system. The result showed that an average water level
of 1.0 - 1.7 m should be maintained at Hanoi during the increased release period.
