However, there are also factors that would affect the trees from growing healthily. Some of the trees would not receive the right amount of energy and sediments can possibly be mix with the good soil.

It is best that we examine why the flooding occurred. There could be other possible reasons for flooding. It can be pollution caused by people throwing their garbages anywhere.
