Question

Why are inundation canals not as popular as perennial canals?

Answer 1

1. Seasonal Availability: Inundation canals draw water only during the flood season when river water levels are high, making them unreliable for year-round irrigation.
2. Unpredictability: The water supply in inundation canals depends on natural river flooding, which can be irregular and uncertain, affecting crop planning and yield.
3. Lack of Control: These canals lack regulatory mechanisms to control water flow, leading to either shortage or excessive water, both of which can harm crops.
4. Limited Reach: Inundation canals usually serve areas close to the riverbanks, whereas perennial canals can transport water over greater distances due to controlled distribution from dams or barrages.
