How did flooding hurt river civilizations?
The floods improved the soil but could destroy homes and crops. The waters could cause massive losses, but they also led to the development of irrigation systems. How did the flooding of the Tigris and Euphrates Rivers contribute to the development of ancient Mesopotamia?
How does development affect flooding?
In the past, development has taken place on areas of land at relatively high flood risk, where often building has pressed tightly up to the river bank. These factors make urban areas more prone to river flooding and there is potential for run-off from new development to exacerbate river flooding downstream.
How do floods affect the world?
Floods have large social consequences for communities and individuals. As most people are well aware, the immediate impacts of flooding include loss of human life, damage to property, destruction of crops, loss of livestock, and deterioration of health conditions owing to waterborne diseases.
How does urban development affect flooding in the United States?
Over the past century, the United States has become an increasingly urban society. The changes in land use associated with urban development affect flooding in many ways. Removing vegetation and soil, grading the land surface, and constructing drainage networks increase runoff to streams from rainfall and snowmelt.
How to prevent flooding from waterways and rivers?
Discourage the public from throwing debris into the river by having bins available. Education programs on the impact of trash to waterways and wildlife are effective in preventing waste buildup that leads to flooding. Signage near a waterway raises awareness of the problem.
What causes a large body of water to flood?

How does development affect the level of water in a stream?
Development along stream channels and floodplains can alter the capacity of a channel to convey water and can increase the height of the water surface (also known as stage) corresponding to a given discharge.
