Which process can cause pooling of water in irrigation areas?

Pooling of water in irrigation areas primarily occurs due to poor slope management. Proper grading and slope in an irrigation area are crucial for facilitating adequate drainage. When slopes are not managed correctly, water can accumulate in low-lying areas instead of draining away as intended. This can lead to excessive moisture levels, which may create conditions that encourage water pooling.

In contrast, inadequate watering schedules might lead to underwatering or overwatering at inappropriate times but do not directly cause pooling. Excessive transpiration is a process that generally reduces the amount of water available in the soil, while incorrect soil types can impact water retention and drainage but are less directly related to pooling compared to slope management. Thus, when slopes are poorly managed, it significantly increases the likelihood of water pooling in irrigation areas.
