Explain how the use of heavy machinery in an area can lead to an increase in the severity of flooding

soil compaction causes floods because rainfall water cannot infiltrate into the soil.

Explanation:

The use of heavy machinery in an area for urbanization and other purposes have always caused a series of problems to the top soil. One of the major consequence of such activity is the compaction of soil. Soil compaction is caused when stress is applied into the soil and the density of soil increases as a result.

It has been found that soil compaction causes floods because rainfall water cannot infiltrate into the soil due to the compact density of soil. The water instead ends up in the surface which subsequently causes floods.
