    Study Notes

    Cross Drainage Works

    • Cross drainage works involve the construction of structures to divert the flow of water from a natural watercourse or drainage basin to another watercourse or drainage basin.
    • The primary objective of cross drainage works is to prevent waterlogging, flooding, and erosion in the donor basin, while also increasing the water availability in the recipient basin.
    • Cross drainage works can be implemented through various methods, including the construction of canals, tunnels, and pipelines.
    • These works can be used to transfer water from a surplus basin to a deficit basin, helping to meet the water demands of irrigation, industry, and municipal supplies.
