Two factors leading to several droughts during the dry season and catastrophic floods during the rainy season are the imbalance of two seasons and the upstream dam effect. With the agricultural economy of the country and the millions of citizens’ lives involved in the rivers, ensuring dam safety, sustainable water source management, and solving climate change risks is dramatically necessary [2]. This article analysed water management and dam safety from the international experience and particular countries, thereby proposing solutions to develop sustainably, manage dam safety and restrict the adverse impacts of natural disasters in Vietnam.
