how cutting of plant result in flood and drought?

Dear Student,

Deforestation leads to floods because:
 
Trees prevent sediment runoff, because the roots of the trees absorb water from the soil. This makes the soil dry. The dry soil is able to store more rainwater. In absence of trees the soil is not able to hold large amount of water and the water runs off in the rivers. This causes the rivers fill more quickly they are much more prone to floods.
 
Deforestation leads to drought because:
 
The trees helps in maintaining water cycle in nature. They absorbs water from the soil and distributes it in the atmosphere by the process of transpiration. The accumulation of these water vapours in the atmosphere is one of teh reason of rainfall. Now in the absence of trees this process does not take place and leads to low rainfall. Thus, causes drought in that area.
 
Hope this will help you,
All the best !!
