Zhang, Y., Wu, P., Zhao, X. and Wang, Z. 2013. Simulation of soil water dynamics for uncropped ridges and furrows under irrigation conditions. Can. J. Soil Sci. 93: 85–98. The ridge-furrow planting system combined with furrow irrigation can effectively increase soil moisture storage and improve water use efficiency in the semi-arid region of China. The precise soil water dynamics in ridge-furrow systems must be known in order to properly design ridge-furrow geometry and improve irrigation uniformity while reducing deep water percolation. The objective of this study was to investigate soil water distribution in the cross-sectional ridge-furrow infiltration, through laboratory experiments and numerical simulations. Six experimental treatments with three soil types (silty clay loam, silt loam, and sandy loam) were tested to monitor both soil water movement and cumulative infiltration in rectangular soil chambers. The HYDRUS-2D model was calibrated and experimentally validated to simulate soil water dynamics....
