Abstract: To research the water retention performance of lowland heightening farmland protection project in Tingzikou Water Control Pivot, large-scale soil column experiments and one-dimensional saturated-unsaturated flow simulations have been performed. The results show: (1) 70 cm thick arable soil layer with appropriate compaction can ensure satisfying water retention performance; (2) the established model and the results obtained in the paper can provide a reference for similar projects.

Key words: Tingzikou Water Control Pivot, lowland heightening, water retention performance, numerical simulation
