Characteristics of sediment sorting and Characteristics of sediment sorting and sediment bound organic carbon loss under different soil organic carbon levels
Description
This study investigated the changes in sediment yield, sediment effective particle size distribution, and sediment bound organic carbon (SBOC) loss in six soils with varying SOC contents during the rainfall process, explored the impacts of SOC content on sediment sorting and SBOC loss, identified the dominant controlling factors and primary pathways of SBOC loss. The uploaded data includes sediment yield, hydraulic parameters, sediment particle composition, and sediment organic carbon content of different soils under different simulation experiments.

Steps to reproduce
This study collected six soil with varying SOC contents and conducted simulated rainfall experiments with varying rainfall intensity (60, 90 and 120 mm h-1) and slope gradients (10, 20 and 30°). Runoff samples were collected to analyze the changes in sediment yield, sediment effective particle size distribution, and sediment bound organic carbon loss. specifically, a laser diffraction particle size analyzer (Mastersizer 2000, Malvern Instruments Ltd., UK) was used to measure their particle size distribution. And the potassium dichromate oxidation-outer heating method was used to measure organic carbon content.
