New insights on optimizing aeolian–fluvial sediment source fingerprinting using geomorphic controls and correction factors——Case study: Lake Urmia sand dunes, NW Iran

Accurate identification of sediment sources remains a major challenge in sediment fingerprinting due to uncertainties associated with tracer selection, model structure, and the lack of geomorphically...

Estimating monthly suspended sediment load of the Brahmaputra River by integrating machine learning models with unsupervised outlier detection

Suspended sediment load (SSL) modeling is crucial in hydrology and river engineering for infrastructure design, river basin management, flood mitigation, and channel change studies. Monitoring SSL often...

Uncovering the mechanisms of cross-shore sediment transport through interpretable machine learning with limited laboratory data

Cross-shore sediment transport, a key driver of coastal morphodynamic evolution, remains challenging to model due to the simultaneous contributions of multiple factors, which collectively result in...

Distinct mechanisms influence the variations in soil shear strength between collapsing walls and non-collapse profiles in the hilly granitic region of south China

Soil shear strength is a critical mechanical property governing the stability of collapsing walls in Benggang erosion, a severe form of land degradation in the granitic hilly regions of southern China....

Effects of roots and canopy of Medicago sativa L. on soil and water conservation for steep spoil heaps

Spoil heaps are vulnerable to intense rainfall, and the understanding of the impact of vegetation on runoff and sediment production is limited. Models of spoil heaps with dimensions of 3.46 m × 2.00...

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...

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...

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...

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,...

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....

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...

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...

Fortnightly variation in sediment-induced stratification in a macro-tidal estuary and its impacts on sediment movement

Understanding the evolution of density stratification in estuaries is essential due to its significant impact on hydrodynamics and material transport processes. In this study, the Environmental Fluid...

This study aims to investigate the factors influencing modern beach development along the southeastern Bengal Basin coast by analyzing the grain size and heavy mineral (HM) distribution in sediment....

A retrogressive erosion model with automatic adjustment for sediment entrainment dominated and mass failure dominated bed deformation

Retrogressive erosion, a critical process impacting river engineering structures, channel geomorphology, and reservoir sediment management, manifests primarily in two distinct forms: rotating and stepped...

Numerical simulation of bacteria and virus transport in mobile bed channels

Pathogen transport in irrigation canals was simulated via a one-dimensional hydrodynamic and sediment transport model. The governing equations are St. Venant for sediment-laden flow and convection and...

Comparative contribution of planted and natural forest to sediment yield using biological indicators of TOC and n-alkanes

Understanding sediment sources and budgeting is crucial for effective watershed management and soil conservation. This study employs n-alkanes as biomarkers to trace sediment origins in a small watershed...

Influence of flow unsteadiness on local scour at bridge piers: An energy-based perspective

Local scour at piers is a major cause of bridge failures worldwide. While most existing studies assume steady flow conditions, actual flood events are inherently unsteady, with distinct rising and falling...

Analytical and experimental study on sediment wash-off from urban road surface under rainfall runoff

Accurately modeling sediment wash-off from urban roads is critical for stormwater pollution control but remains challenging due to the limited physical basis of existing transport models. This study...

Effectiveness of bioengineering and geosynthetic integration for riverbank erosion control: A case study along the Mae Taeng River, Chiang Mai, Thailand

This study evaluates the performance of erosion control measures incorporating geosynthetic materials and bioengineering approaches to mitigate riverbank erosion along the Mae Taeng River in Chiang...

Bed shear stress estimation of shallow and wide flows over sandy beds in transitionally rough regime at threshold conditions using velocity characteristics

Estimating bed shear stress (BSS) is essential to determine the critical shear stress under incipient motion conditions of sediments which typically occur within transitionally rough regime for sandy...

Potential utilization of marine sediments from the neritic zone as adsorbents for dye and heavy metal removal: A comprehensive review for supporting sustainable development goals

Water pollution caused by synthetic dyes (including azo, cationic, and anthraquinone dyes) and heavy metals (Pb, Cd, Cr, Cu, Ni, and Zn) presents a significant environmental challenge, necessitating...

Hydrodynamic effects of riparian vegetation in an anabranching-confined transition reach in the middle Yarlung Tsangpo River
