If all the rain water is harvested for recharging ground water, will it affect the flow of rivers? Explain your answer in detail. 

Dear student,     
Please find below the solution to the asked query                                                             

Yes, the flow of rivers will be affected if all the rainwater is harvested for recharging groundwater. Groundwater is recharged by:

• Harvested rainwater
• Water from water bodies on earth’s surface: It passes through the soil by the process of infiltration. The infiltrated water then gets accumulated in the aquifer deep under the ground to recharge the groundwater. 

So, if both river water and harvested rainwater is used to recharge groundwater only, the flow of rivers will get affected.
