Cause analysis of the centennial trend and recent fluctuation of the Yellow River sediment load
Shui kexue jinzhan, 2020 The trend of the Yellow River sediment load in future is related to the development of the river basin management strategy in the new era. It has great significance to clarify the sediment load feature for the determination of future trend, especially ...

Study on Sediment Discharge of Watersheds from Reservoir Sedimentation.
Journal of Japan Society of Hydrology and Water Resources, 1998 近年,竣工したダム数の増加に伴って,貯水池の堆砂量データが次第に豊富となり,多様な解析が可能になってきている.本研究は,主として電力用貯水池の堆砂量データを検討し,その経年変化状況および堆砂の速度と,流域や貯水池の諸因子との関係を調べたものである.堆砂量の経年変化には種々のタイプがあり,貯水池上流端の背砂がこれに関係すると推定される.このため,背砂形成に関しての三角州や扇状地からの類推から,タイプに関わる流域や貯水池の説明因子を選定した.また,比堆砂量はタイプに応じて算定する必要があることを示した.タイプや比堆砂量に関わる要因分析の結果,従来から言われているように,これらの分析には重相関的な考察が必要である.本研究では,数量化法を用いて2,3の解析を試みたので,その結果を紹介する.

A comparative study of the flux and fate of the Mississippi and Yangtze river sediments [PDF]
Proceedings of the International Association of Hydrological Sciences, 2015 Large rivers play a key role in delivering water and sediment into the global oceans. Large-river deltas and associated coastlines are important interfaces for material fluxes that have a global impact on marine processes. In this study, we compare water

SUSPENDED SEDIMENT DISCHARGE ON A NON-TIDAL COAST
Coastal Engineering Proceedings, 1982 A field study was conducted on a non-tidal sand beach to measure the relationship between wave energy and the longshore transport of suspended sediment. The range of suspended sediment concentrations was similar to that reported elsewhere. The relation between longshore transport and longshore energy flux derived from this data set is about half that ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Sediment traps with guiding channel and hybrid check dams improve controlled sediment retention [PDF]
Natural Hazards and Earth System Sciences, 2018 Sediment traps with partially open check dams are crucial elements for flood protection in alpine regions. The trapping of sediment is necessary when intense sediment transport occurs during floods that may endanger urban areas at downstream river ...
