Overflowing rivers
Broken dams
Urban drainage basin
Storm surges
Tsunamis
channels with steep slides
Lack of vegetation

Droughts
causes are:
Air circulation
Weather patterns
Soil moisture depleted
Surface temperatures rising
Less water available
heat waves
causes are:
Air from upper levels are pulled down to the ground
atmospheric pressure
High pressured inhibit winds
Lightning
