5.3. Remedial Measures

Provision of surface and subsurface (tile) drains.

Surface and subsurface drains are designed to remove excess water from the soil, helping to control water logging. Surface drains are open ditches or trenches that collect and channel runoff water away, while subsurface drains consist of pipes laid below the soil surface that catch excess groundwater. By implementing these systems, we can effectively manage soil moisture levels.

Think of surface drains like a gutter system on a house. Just as gutters channel rainwater away from the roof to prevent leaks and flooding, surface drains help prevent water from pooling in fields, which can harm crops.

Restriction and improved scheduling of irrigation.

Improved scheduling of irrigation refers to applying water only when necessary. This practice reduces the overall amount of water used and minimizes the risk of over-irrigation, which can lead to water logging. Farmers can utilize tools like moisture sensors and weather forecasts to decide the optimal times to irrigate, ensuring crops get just the right amount of water.

Consider how you might water your houseplants. Instead of watering every day regardless of the conditions, you observe the soil. If it is still moist, you wait another day. This careful timing prevents over-saturation, just like improved scheduling helps farmers avoid excess moisture in their fields.

Canal lining to reduce seepage.

Canal lining involves applying a layer of material to the canal's inner surface to prevent water from leaking into the ground. This is critical because seepage can lead to loss of water that could be used for irrigation. By using materials like concrete or synthetic liners, the efficiency of water transport improves, ensuring more water reaches the fields where it's needed.

Think of a lined canal like a water bottle. If your bottle has no cracks, it holds water efficiently. If there were cracks or holes, that water would seep out and be wasted. Similarly, lining a canal ensures that all the water stays where it's supposed to be.

Deepening/protecting natural drains.

Natural drains in the landscape already serve to remove excess water. By deepening these drains, we can enhance their capacity, allowing them to carry away even more water during heavy rainfall or irrigation events. Protecting these drains from obstruction (like sediment or vegetation) is also crucial, as blockages can cause backup and waterlogging.

Imagine a creek in your yard that helps drain excess rainwater. If the creek is shallow and gets filled with dirt or leaves, water will overflow into your yard. By regularly cleaning the creek and possibly deepening it, you keep the water flowing smoothly, preventing flooding—just like maintaining natural drains in agricultural fields helps to avoid water logging.

Conjunctive use of shallow tube wells.

Using shallow tube wells in conjunction with surface water can help manage and balance water supply. When surface water is plentiful, it can be used first; during dry periods, tube wells can supply groundwater, ensuring crops receive the needed water without overwhelming the soil. This strategic combination of resources prevents over-reliance on one source and helps maintain a stable water table.

Think of it like having a mixed strategy for your finances. If one income source is strong, you rely on it. But in tough times, you tap into savings or another job. Using both surface water and tube wells is like diversifying your income to keep everything stable.
