Flooding: riverine and storm surge
Riverine flooding happens when heavy rainfall in the catchment causes high water levels in rivers or creeks to overtop the banks.
The flood level in the river is determined by the amount of rainfall that has fallen in the catchment, how long it has rained for and how widespread the rainfall is.
Riverine flooding is one of the major natural disasters in the Northern Territory.
Several communities and towns are prone to riverine flooding and can be affected by restricted access from days to weeks.
All tropical cyclones near the coastline are able to produce a damaging storm surge that can increase the sea level for several hours and affect hundreds of kilometres of coastline either side of the cyclone track.
The surge will depend on the level of tide at the time.
