How do we ascertain the percentage of water recharge available through sub-surface wells?

Dear Sir/Madam,

I am a practitioner working on watershed development. I work in Odisha which is a high rainfall area (1200-1400 mm annual rainfall) and in areas where the main source of irrigation is open wells. There are very few bore/tube wells.

I seek your assistance is suggesting papers/sharing your thoughts on the following questions:

1. During monsoon what% of rainfall is retained in the subsurface soil, which is available through shallow wells?

2. How long the subsurface water available in shallow wells after monsoon?

3. If the water has been withdrawal from shallow wells for irrigation, how long it takes to recover? (Apart from the parameters of soil texture and geology)

4. If a borewells has been pumped, does it also reduce the water in shallow wells. Are there any thumb rules guiding this?

Your suggestions would be very helpful.
