Multidimensional assessment and precision restoration strategies for soil erosion in karst areas: Based on multi-scenario simulation

Karst landscapes are plagued by severe soil erosion due to their fractured lithology and complex hydrology, posing persistent challenges to erosion assessment and ecological restoration. However, current...

Study on the critical velocity of sediment incipient motion in saline water based on Hangzhou Bay field investigation

The critical condition of sediment incipient motion (SIM) is one of the most pivotal and fundamental topics for the mechanics of sediment transport in offshore areas. The flocculation of fine sediment...

Experimental measurement of flocculation and settling behavior in fine sediments from the Three Gorges Reservoir, China

Flocculation of cohesive sediments is widely observed in natural aquatic-sedimentary environments, such as river estuaries and nearshore coastal waters, where salinity, suspended sediment concentration...

Highly active sediment transport induces morphodynamic changes exacerbating flash flooding

Rainfall-induced flash floods often trigger active sediment transport and substantial morphological changes, which in turn affect flood dynamics. Previous numerical studies have mostly overlooked the...

Variability in rill morphometry, surface runoff and erosion with soil conservation techniques (application of polyacrylamide and rice husk biochar and hydromulching) in deforested hillslopes under simulated rainfall

This study analyzed the effects of very intense rainfall (98 mm/h for 30 min) on soil left bare or treated with polyacrylamide, rice husk biochar and hydromulching. Rill morphometry, surface runoff...

Sensitivity and complexity of the Yangtze River’s sediment dynamics

The Yangtze River, the world’s longest river flowing entirely within one country, has experienced a 60 %–99 % decline in sediment load since the late 1970s. Climate change and human activities are widely...

Granular segregation of layered sand beds around vertical piles under cyclic lateral vibrations

Recent studies on noncohesive sediment bed deformation and granular segregation induced by localized vibration from embedded vibratory piles indicate that vibrating vertical piles in uniform noncohesive...

Changes in beach sediment mineralogy and grain size associated with pelagic Sargassum landings

Massive influxes of pelagic Sargassum spp. have caused significant environmental, social, and economic impacts across the tropical Atlantic. The accumulation of these macroalgae on beaches represents...

Suspended sediment concentration prediction using a hybrid VMD-LSTM-SA-ensemble model

Accurate prediction of suspended sediment concentration (SSC) is critically important for water quality assessments in marine and terrestrial aquatic environments. However, there is uncertainty associated...

Fluvial runoff‒sediment hysteresis at the flood event scale in a typical semiarid watershed

River runoff and suspended sediments exhibit high dynamic and multiscale variability, particularly during rainstorm-driven floods in arid and semiarid regions. Despite the widespread use of the hysteresis...

Case study of toe scour and deposition at seawalls in the Qiantang River estuary

In tidal estuarine regions, toe scour and deposition at seawalls, which are influenced by runoff and tidal flow, present complexities not found in inland rivers and wave-dominated coasts. Existing methods...

Sedimentological and diagenetic controls on burrow fillings in the upper Jurassic Hanifa formation, central Saudi Arabia: Implications for porosity and pore system variations in bioturbated reservoirs

Evaluating the petrophysical properties of carbonate strata with bioturbation necessitates an insight into the heterogeneity in rock texture within burrow fillings. This study examines five separated...

Underestimated environmental risks: Sediment stability weakening from accumulation of biomass in a eutrophic lake induced by microplastics

Sediments had emerged as a significant repository of MPs (microplastics) and biomass accumulation in eutrophic lakes, yet the mechanisms by which these particles impact sediment stability remained elusive....

Quantifying sediment yield and discharge fluctuations using the GeoWEPP in response to soil and water conservation practices

Owing to the overuse of wild land, the mountainous watersheds in Iran have experienced severe land degradation and consequent downstream flooding. To design effective soil and water conservation strategies,...

Assessment of heavy metal concentrations in seabed sediments of the coral ecosystem in Bangladesh: An in-depth analysis of ecotoxicity and ecological health

Saint Martin Island (SMI), the first coral reef ecosystem at the Bay of Bengal is ecologically significant for its unique biological richness. The purpose of this study is to monitor environmental health...

Magnetic properties of surface sediments in a closed alkaline volcanic lake: A case study from Lake Batur, Bali, Indonesia

Lake Batur is a closed volcanic lake with alkaline water, located on the island of Bali, Indonesia. This study of Lake Batur presents a comprehensive rock magnetism analysis of the sediments and a geochemical...

Sediment load complexity downstream of the Three Gorges Project via the multiscale entropy analysis method

The Three Gorges Project (TGP) plays a pivotal role in flood control, power generation, and water resource management along the Yangtze River. Nevertheless, its construction and operation have profoundly...

Spatiotemporally varied contributions of primary bank-derived materials from ungaged areas to the Three Gorges Reservoir: Insight from decadal continuous sediment archives (2012–2022)

Accurate quantification of sediment sources is essential for assessing bank erosion, mitigating reservoir sedimentation, and ensuring long-term sustainability. However, estimates for ungaged areas remain...

Effects of three plant root systems on rill erosion characteristics on coal dump slopes under simulated experiments

Dump slopes have experienced severe rill erosion and threaten the safety of the ecological environment. Although vegetation restoration has improved the ecological environments of mining areas, because...

Local erosion and mound formation induced by turbulent slurry wall jets in crossflow

This paper presents the results of experimental investigation on the local erosion and mound formation induced by slurry turbulent circular wall jets in crossflow and with the presence of a secondary...

The relationship between flow depth and hydraulic parameters for high surface roughness of vegetation stem cover under laboratory simulation

Grass, shrubs and tree stems can increase flow depth and resistance and prevent soil erosion, and it is necessary to quantify the relationship between flow depth and hydraulic parameters for high surface...

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

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...
