Gully is the dominant sediment source of snowmelt erosion in the black soil region – A case study
2022, Soil and Tillage ResearchCitation Excerpt :Haddadchi et al. (2015) reported that a potential source closer to the sediment sampling sites is more likely to contribute dominantly to the sediment content. The study catchment belongs to rolling hilly region of Northeast China with low sediment delivery ratio (Dong et al., 2013). The limited power of snowmelt runoff led to reduced sediment from topsoil (e.g. cultivated land, forest, and unpaved road) being able to reach the gully bottom.
Identification of sediment sources and exploration of scale effects in the black soil region of Northeast China
2020, CatenaCitation Excerpt :In addition, the sediment sampling sites were located close to the gully sides and sediment only needed to be carried a short distance to reach the bottom of gully. The study area is located in an area where hill slopes are characteristically long and smooth, and the sediment delivery ratio is low (Dong et al., 2013). Therefore, less erosive sediment from topsoil can reach the streams, resulting in a relative increase in the contribution from gullies.
Impact of land use changes on catchment soil erosion and sediment yield in the northeastern China: A panel data model application
2020, International Journal of Sediment ResearchUsing reservoir deposits to quantify the source contributions to the sediment yield in the Black Soil Region, Northeast China, based on the fingerprinting technique
2019, GeomorphologyCitation Excerpt :These results suggest that implementation of soil conservation measures and conservation tillage effectively reduced the relative contribution of cultivated topsoil to the sediment deposited in the reservoir, and the relative contribution of the gullies correspondingly increased. In many cases, only 1–3 sampling sites were used to characterize the deposition in a small reservoir (Dong et al., 2013; Fang, 2015; Zhang et al., 2015). However, the number of sampling sites was not enough to provide accurate information on sediment deposition and provenance, and more sediment cores needed to be collected from different locations in the reservoir.
Using reservoir deposits to reconstruct the impact of recent changes in land management on sediment yield and sediment sources for a small catchment in the Black Soil region of Northeast China
2019, GeodermaCitation Excerpt :When compared with the evidence of high rates of soil loss in the region, this value is relatively low and this reflects the low catchment sediment delivery ratio (SDR). Dong et al. (2013) report a study of sediment delivery from the 27.29 km2 Hebei catchment within which the study catchment is located. This suggests that gross erosion rates within the larger catchment are about 20 t ha−1 year−1 and that the catchment SDR is ca. 0.1.
