The direct measurement is a method that uses equipment (e.g., pressure plate and tensiometer) to measure the water content of the soil under a certain matric ,suction,. This method can only measure SWCCs in a specific state (the same dry density or void ratio). Also, it is difficult to use a single method to measure SWCCs in the full ,suction, range.
