4/19/2023 0 Comments Flood watch![]() Combined with gale force onshore winds, this can lead to flooding of low-lying coastal land.įlash flooding can occur quickly due to heavy rainfall and you may not receive an official warning. The low pressure causes sea level to rise as there is less air pressing down on the sea. Storm surge occurs when sea levels are elevated above the usual tidal limit due to the action of intense low pressure systems over the open ocean. Should a dam failure occur, significant downstream flooding can involve potentially swift flowing water and high amounts of debris. In Victoria dam safety is monitored, and warning arrangements are in place to warn downstream residents of potential dam failure threats. Dam failureĪlthough dam failures are rare, their effects can be significant. Flash floods are generally defined as developing in six hours or less from rainfall to the onset of flooding. Flash floodingįlash flooding occurs when soil absorption, runoff or drainage cannot adequately disperse intense rainfall, and is usually caused by slow-moving thunderstorms. Inland floods with low gradients have floods that move slowly down the river, sometimes lasting for several months. ![]() ![]() ![]() Coastal rivers with short, steep headwaters often have floods that rise and recede quickly. The nature of riverine flooding can vary significantly in terms of cause, timing and depth between different locations. In riverine flooding, relatively high water levels overtop the natural or artificial banks of a stream or river.
