Question

Give reasons for the following.

Well irrigation is more common in the alluvial plains.

Answer 1

1. Soft alluvial soil is unconsolidated and deep, making it relatively simple, fast, and inexpensive for farmers to dig open wells or drill tube wells.
2. A high water table is present in these plains due to the porous nature of the soil, which allows rainwater to easily percolate down and collect underground.
3. Perennial river systems that run through these plains provide constant groundwater recharge, ensuring a consistent water supply even during the dry summer months.
4. Pumping machinery, distribution channels, and rural electric power lines can all be easily installed on flat, level terrain.
5. The intensive cultivation of crops such as wheat, paddy, and sugarcane in this fertile region produces a massive, ongoing demand for a controlled and dependable irrigation source.
