Pick up the correct equation from the following :

[A]. Run off = Surface run off + Ground water flow
[B]. Run off = Surface run off - Ground water flow
[C]. Run off = Surface run off / Ground water flow
[D]. Run off = Surface run off x Ground water flow.

Answer: Option A

There are three type of run-off.

1. Surface run-off.
2. Sub surface run-off.
3. Ground water flow.

I think it should be B.

Chinni said: (Jan 23, 2018)  
Ground water flow is not considered as run off as per my knowledge.

Vaibhav Kanjarekar said: (Jun 11, 2018)  
I think it is option B.

Yaswanth said: (Aug 11, 2018)  
Option B is correct. Because runoff is always available over the surface and it is the water which is available after considering all the losses. Ground water is also one of the losses.

Teshayneh said: (Oct 30, 2018)  
B is the correct answer. I too agree.

Sachem said: (Mar 16, 2019)  
B is the correct answer.

Sudhakarda said: (Jun 5, 2019)  
Option B is correct.

Pavan Kumar Gupta said: (Jul 4, 2019)  
B is the correct answer.

Amir Mesfin said: (Aug 9, 2019)  
Total run off = surface Runoff + subsurface(ground water) runoff.

So, A is correct.

Aditya Singh said: (Aug 21, 2019)  
Given answer A is right.

Runoff also includes groundwater that is discharged into a stream; streamflow that is composed entirely of groundwater is termed base flow or fair-weather runoff, and it occurs where a stream channel intersects the water table.

Rahul Rajput Nitian said: (Jul 2, 2020)  
Given Answer right.

Runoff is classified into two categories. 1-Direct runoff 2-Base flow. Groundwater flow comes under base flow.

Andy Prakash Bhatt said: (Jul 9, 2020)  
B is correct, groundwater flow is termed as run in not run off.
