Water Harvesting Structures in Kerala
- Surangams: Surangams are traditional tunnel wells that are commonly found in the hilly regions of Kerala. These wells are typically dug into the hillsides, allowing water to flow into them and be stored for later use.
- Bundhis: Bundhis are small earthen dams or embankments that are constructed across streams or rivers to create reservoirs for storing water. These structures help in the conservation of water and prevent it from flowing away.
- Nadis: Nadis are traditional irrigation canals that are used for the purpose of water harvesting in Kerala. These canals are designed to divert water from rivers or other water bodies and distribute it to agricultural fields and other areas.
- Kattas: Kattas are small check dams or weirs that are constructed across streams or rivers to impound water. These structures help in controlling the flow of water and allowing it to percolate into the ground, thereby recharging the groundwater table.
These water harvesting structures play a crucial role in mitigating water scarcity and ensuring sustainable water management in Kerala. They help in capturing and storing rainwater, which can then be used for various purposes such as irrigation, drinking water supply, and groundwater recharge. Additionally, these structures also help in preventing soil erosion and conserving water resources.
