Steps |
Data requirement |
|
1 |
Estimate Soil water balance component for selected micro-watershed |
Section 6.5 - Annexure 5, #5 ?? |
|
2 |
Estimate water availability in micro-watershed using 1. Measured capacities of surface water bodies 2. 30% of runoff generated through watershed based on runoff from Infiltration method 3. Amount of water percolation in soil-ground water (deep percolation component in water balance) |
|
|
3 |
Estimate water required for irrigation based on the crop water requirement and irrigation requirement |
Section 6.5 - Annexure 5, #4 ?? |
|
4 |
Estimate water requirement for household use |
|
|
5 |
Estimate water required for livestock purpose |
|
|
6 |
Estimate water available for irrigation by subtracting water requirement for human and livestock from total water available in micro watershed |
|
|
7 |
Display water budget for micro-watershed and higher levels |
