Bank erosion under the impacts of fluvial erosion, frost heaving/freeze-thaw process of rivers in seasonal frozen regions

Heliyon
Bank erosion is a key feature of channel evolution in alluvial rivers, and will occur under the combined effect of hydraulic erosion and frost heave/freeze-thaw process of rivers in seasonal frozen regions. However, most research on bank erosion modeling

Deep Sea Sedimentation

Environmental Health Perspectives, 1974
An important problem in the study of microparticles in the marine environment, suspended in the water column or deposited as sediment on the ocean bottom, is the determination of provenance of the microparticles-where did they come from and by what processes were they transported to the sampling location?

Assessing Differences in Groundwater Hydrology Dynamics Between In Situ Measurements and GRACE-Derived Estimates via Machine Learning: A Test Case of Consequences for Agroecological Relationships Within the Yazoo–Mississippi Delta (USA)

Hydrology
In situ groundwater monitoring is critical for irrigated agroecosystems and informs land cover changes. Yet, such data can pose management challenges and confound agroecological relationships.

Insights into the impacts of inflow discharge variation on cross-sectional topography in the upper neck area of a laboratory-scale subaerial delta from SWJ–LSTM simulations

International Journal of Sediment Research
Rivers significantly influence delta morphology and sedimentation patterns. However, the dynamic effects of rivers on the upper neck areas of subaerial deltas, which are the complex zones connecting main channels to distributary networks, remain ...
