Excessive rainfall, a burst dam or riverbank, unusually rapid snowmelt, and tidal surges are some immediate reasons for flooding. But what causes floods in one environment may be very different to what causes floods in another area.
In coastal regions storm surges - seawater swollen by intense rain and driven inshore by strong winds and waves - can be devastating, especially if natural breakwaters like coral reefs or mangrove forests have been destroyed. In urban environments, heavy rain rapidly runs off roads and pavements into drainage systems that sometimes cannot cope. In mountainous areas, trees and soils absorb water, but if the forests are cleared the land is vulnerable to erosion and heavy rain can lead to flooding, landslides, and clogging up of rivers with debris washed off the hillsides.
As climate change takes its course, wet areas are predicted to get wetter and storms to increase in frequency and intensity leaving flood-prone areas more vulnerable than ever.
One way could be cutting down trees.
Trees help control floods, without trees...the space is cleared and the flood is faster, with soil (can also make an ugly mudslide/flood)

People contribute to causes of floods by littering, polluting, overfarming, and cutting trees that protect riverbanks.
Monsoons can create floods and make rivers overflow
Humans pollute the atmosphere, which warms the earth, and the water, making hurricanes more likely, which cause floods.
.
Humans farm and that changes the land. They also build cities and that affects how water is absorbed into the soil. So yes, humans increase the risk of flooding.
In some ways both, and in some ways niether. Floods are primarily a weather phenomenon, as the ultimate deciding factor is usually heavy rain or melting snow. However, the geology of an area can affect the risk of flooding. Low lying areas, especially valleys, are usually the most vulnerable. Human acitivty can also increase flooding risk, such as by removing vegetation and by building impermeable surfaces such as roads.
Floods cause major damage to crops and property and endanger people's lives.
what do humans do to increase the rate of weathering
False

Elevated ridges on the side of a river, called leevees can be built to decrease the risk of flooding.

Because sometimes when humans control floods they can cause damage to nearby areas.
The government had responded by rescuing the people more likely at risk from the floods.
By asking more intellectual humans to answer this questions =)
Humans have changed the natural environment to increase the risk of flooding by cutting down trees ( Deforestation ). The trees act as a kind of flood barrier as their roots take in some of the water and the trunk of the tree slows down ground flow. Hope this helps :D
humans are making the sea level rise so there is more rain and floods
Floods cause major damage to crops and property and endanger people's lives.
Insurance pool risk by providing protection against disastrous risk such as fires,floods,earthquakes,accidents
floods and often flashflooding can occur
Flash floods - a big killer of humans in desert regions.
