Question

Quizplus · Accepted Answer

Downstream floods affect larger areas than flash floods and are commonly more deadly. These floods occur when water accumulates in the lower parts of a river basin, causing the river to overflow its banks and flood the surrounding areas. They are most common in areas with a large watershed or a long stretch of river, and are often caused by prolonged rainfall or snowmelt. Downstream floods can cause significant damage to infrastructure, homes, and crops, and can also result in loss of life.
