Question

Why well irrigation is more popular in Northern plains than Peninsular India?

Answer 1

Well irrigation is more popular in the Northern Plains than in Peninsular India due to the following reasons:

1. Soft Alluvial Soil: The Northern Plains have soft, deep alluvial soil that makes drilling and excavating wells easy and economical. In contrast, the Peninsular Plateau is composed of hard, crystalline rocks that are difficult to drill through.
2. High and Perennial Water Table: The Northern Plains are regularly recharged by perennial, glacier-fed Himalayan rivers, which keep the groundwater table high and consistent all year. Peninsular rivers, on the other hand, are seasonal, causing the water table to decrease dramatically throughout the summer.
