Abstract:Subsurface water flow can cause serious soil erosion on sloping farmland. Sediment transport capacity (Tc) data at different subsurface water flow depths are limited. The objective of this study was to develop a new equation that can accurately determine Tc under subsurface water flow impacts. Subsurface water flows were arranged at three depths: 15, 10, and 5 cm. Three flow discharges (2, 4, and 8 L min−1) and four slope gradients (5°, 10°, 15°, and 20°) were designed to conduct flume scouring experiments. Th… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
