Questions and Answers
An increase in soil suction beyond Stage 3 results in significant changes in water content.
False
Specific capacity is related to the slope of the Water Retention Curve (WRCC).
True
As the volumetric water content (C(θ)) increases, the water availability from the soil decreases.
False
