- To improve the groundwater level, several civil structures are constructed in the watershed area, pits and trenches.
- The pits or trenches are dogged at equal intervals on the skipping surface to cut the surface – flow and to allow it to percolate through these trenches to enrich the ground level.
- Stone embankment or earthen dams.
- They are constructed to check the surface – runoff in the catchment areas, to enrich the groundwater.
- The farm pond.
- They are constructed near the agriculture field in the catchment area to provide enough surface water to the filed and also to enrich the groundwater.
- Dykes or underground barriers.
- These structures are constructed in the small surface streams e.g. the nallahs, to prevent the free groundwater flow and allow the water-table to come up, to help to improve the irrigation through the dug – wells.
