What is the capillary fringe?

What is the capillary fringe?

• A. Layer of soil that contains no water
• B. Porous material above the water table that may hold water
• C. Depth of saturation in an aquifer
• D. Area where water table reaches the surface

Answer: (B)

The capillary fringe refers to the saturated layer of soil that is located just above the water table. This area consists of porous material that has the capacity to hold water through capillary action. In this zone, water rises from the water table and occupies the small spaces between soil particles, allowing plants to access moisture even when the groundwater level is lower than the surface. The significance of this layer lies in its role in the water cycle and its importance for vegetation. Understanding the capillary fringe is vital for water management and soil health, particularly in agricultural and environmental contexts. This layer's ability to retain water can influence irrigation practices and the overall hydrology of an area. The other choices do not accurately describe the capillary fringe, making it essential to grasp this concept for both practical applications and academic purposes.
