Abstract	In sprinkler irrigated fields, irrigation water is intercepted by crop leaves. This water can be separated into several categories depending on its movement. In this study, the categories are defined as crop stem flow water, leaf storage water, and drop water to the soil. Crop stem flow water is especially effective for crop growth because it reaches the soil surface near the root zone. The objective of this study is to develop a method for quantifying crop stem flow water. Field observation is conducted to observe the movement of irrigation water droplets and to quantify the varying amounts of crop stem flow water, leaf storage water, and drop water to the soil. The measurement of the amount of leaf storage water indicates that droplet movement on the leaf changes constantly. To quantify three components of irrigated water, considering the continuous change of droplet movement on the leaf surface, a simulation model is developed. The simulated amounts of crop stem flow water, leaf storage water, drop water to the soil successfully reproduce the observed result, and model accuracy can be verified.
