A flood is caused by a combination of heavy rainfall. causing river / oceans to over flow their banks, and can. happen at any time of the year, not just in the winter. Floods generally develop over a period of. days, when there is too much rainwater to fit. in the rivers and water spreads over the land.
They can form a dam in the river, causing the water behind the dam to rise and flood the land upstream. If the dam breaks suddenly, then the large amount of water held behind the dam can flood the areas downstream too. Broken ice dams are not the only dam problems that can cause flooding. The ice in the river cracks causing the water to overflow. 2  The ice in the river cracks into pieces. 3  that eventually create a dam causing the water to overflow. 4  The water behind the ice dam collects and when the dam breaks, it causes flooding upstream.
