Response of plunge pool morphology evolution to gully head height of typical grassland in the hilly and gully region of the Loess Plateau

This dataset contains the supporting data for the study "Response of plunge pool morphology evolution to gully head height of typical grassland in the hilly and gully region of the Loess Plateau". The dataset includes:(1) Jet flow hydraulic parameters, including Vpool, τjet, Ekpool and ΔEpool under five gully head heights (0.4, 0.6, 0.8, 1.0 and 1.2 m);(2) Plunge pool morphological parameters, including mean depth (Dmean), maximum depth (Dmax), mean width (W) and mean length (L), extracted from SfM-derived DEMs;(3) Soil and root properties of the gully bed, including soil texture, bulk density, cohesion, penetration resistance, mean weight diameter of water-stable aggregates and root mass density. The data were collected from in-situ scouring experiments conducted on a typical natural grassland slope in the Zhifanggou watershed, hilly and gully region of the Loess Plateau, China.
