Run-off from pavement or smooth rock during rainfall is much greater and faster than run-off from soil or other surfaces as there is little obstruction (friction) to the water flow. These surfaces also absorb very little water, meaning that there is a larger amount of run-off.
This means that waterways can have to deal with large intakes of water in a very short amount of time, often leading to flash flooding, as the waterway can not handle such a large amount of water at once.
Answer:
When the land heats up, the air above it heats up as well. On the other hand, the sea heats up and cools down relatively slowly. Therefore, areas near the sea generally stay cooler during the day and have a more moderate temperature range than inland areas.

The geography of Egypt had a significant effect on the development of the Egyptian civilisation. The Nile flowed through Egypt and flooded every year. The floods brought fresh deposits of fertile soil which ancient Egyptian farmers used to develop a prosperous agricultural economy. The Egyptian civilisation grew from the farmer's crops and all aspects of society were connected in some way to agriculture and the inundation.<span>
