Hurricanes are accompanied by heavy rainfalls and if left unchecked, causes flooding. The function of canals is to diffuse accumulated rainwater and direct it to greater bodies of water.

Is that objects ( living or nonliving) contain spirits

The answer is "Delta"
Delta is a flat triangular shaped land formed when a river carries and deposits

This usually happens where a river is entering an ocean, sea,
lake, reservoir,

The last one happens very rarely (Entering a river).
