What’s the whole question asking what are the options??
<span>When
the water level of a stream or river exceeds its natural banks, it has reached
its flood stage. This is a real panic stage for people living nearby the rivers
and streams that has overflowed its natural banks. This flood situation can
destroy any city or village and also drastically impact the financial situation
of the area. Most cities and states move their citizens away from the river
banks before it reaches this danger stage. Before the emergence of
technological advancement, historical evidence proves that many great cities
were destroyed due to such situations. <span /></span>
The amount of trees in a given location?
As the runoff flows, it may pick up loose bits of soil and sand. Runoff causes more erosion if the land is bare. ... Much of the material eroded by runoff is carried into bodies of water, such as streams, rivers, ponds, lakes, or oceans. Runoff is an important cause of erosion.
hope this helps! :)
