Experimental Data on Gravity Erosion and Non-equilibrium Sediment Transport

This repository contains four sets of raw experimental data derived from a 1:40 scaled physical generalized model of the Qiaogou watershed. The datasets correspond to the core results and figures presented in the related manuscript. File Directory & Contents: 1. Sediment_Concentration_at_Gully_Outlet Contains the instantaneous sediment concentration (kg/m³) data collected at the watershed outlet over time. (Corresponds to Figure 6) 2. Cumulative_Sediment_Yield Contains the cumulative sediment yield (kg) data at the gully outlet over the rainfall duration. (Corresponds to Figure 7) 3. Synchronous_Flow_Velocity_and_Sediment Records the synchronous monitoring data of cross-sectional flow velocity (m/s) and sediment concentration (kg/m³) at three key observation points: Branch Gully, Upstream Main Gully, and Downstream Main Gully. (Corresponds to Figure 8) 4. Geomorphic_Entropy_and_Hypsometric_Curves Contains the discrete slice integration data extracted from pre- and post-rainfall high-precision DEMs. Used to calculate the area-elevation integral (Strahler Integral, S) and Geomorphic Information Entropy (H). (Corresponds to Figure 9 and Table 3) Experimental Conditions (Condition IDs): - OC1: Rainfall intensity 45 mm/h, Control (No deposit) - OC2: Rainfall intensity 45 mm/h, 1× deposit - OC3: Rainfall intensity 45 mm/h, 2× deposit - OC4: Rainfall intensity 90 mm/h, Control (No deposit) - OC5: Rainfall intensity 90 mm/h, 1× deposit - OC6: Rainfall intensity 90 mm/h, 2× deposit Note on Terminology & Units: All variable names, abbreviations, and units correspond directly to the equations and figures presented in the manuscript.
