5.14.1.2. Artificial Causes of Waterlogging There exists a natural balance between the inflow and outflow of a ground water reservoir. This balance is greatly disturbed due to the introduction of artificial irrigation facilities. The surface reservoir water and the canal water seeping into the ground increase the inflow to the ground water reservoir. This raises the water table and the area may become waterlogged. Besides, defective method of cultivation, defective irrigation practices, and blocking of natural drainage further add to the problem of waterlogging.
