Potential of stagnant water due to dam flooding

During rainy monsoon or flood seasons, it often creates pools of stagnant water and dam water levels are lowered in order to avoid dam flooding. Stagnant water or prolonged flood water is known as public health threat or major environmental hazard. Meanwhile, dam flooding is a rapid and uncontrolled release of reservoir volume leads to severe flood in which there will be a significant impact at the downstream, specifically towards the people and environment of the affected region. Apart from causing severe flood, dam flooding also can accumulate stagnant water within a second or worsen the stagnant water if it already exists due to heavy rainfall. This paper is to explain briefly the potential and ongoing research of stagnant water due to dam flooding.
