This study has established and calibrated a three-dimensional system model with a combination of hydraulics-waves and suspended sediment transport with measured data in the study area. Based on the calculated scenarios for the flood and the dry seasons, the results show the occurrence of MTZs in the riparian zone of the Mekong river with typical suspended sediment concentrations (SSC) ranging from 0.04–1.0 kg/m3 dry season and 0.2–1.1 kg/m3 flood season.

This study was carried out to analyze and evaluate the change in the amount of suspended sediment on the Tien River in the Mekong Delta. Evaluating the sediment transport regime is a very important task to effectively serve the assessment of the level of evolution (erosion/accumulation) on the riverbed.

The dynamics of suspended sediments are complicated due to the influence of hydrodynamic factors and the characterization of cohesive sediment properties. A one-dimensional model is built to calculate the vertical distribution of suspended sediment concentration (SSC).

Median diameters (D50) of suspended particles were inferred in the wet season in the Cam - Nam Trieu estuary (Hai Phong, Vietnam) based on the particle size distribution measured by LISST-100X on five transects along the river from 23 to 26 September 2015. The results showed that floc diameters varied between 3.6 μm to 146.5 μm and averaged 49.14 μm.

The coefficients of determination varied from 0.867 to 0.971 (linear relationship), and from 0.95 to 0.991 (proportional relationship). Therefore, turbidity can be used to estimate SPM concentration. However, this relationship changed markedly with the seasons, and hence when determining SPM concentration, seasonal factors must be considered.

In the present study, an open-source coupled numerical model based on Delft3D source code was performed and applied to simulate the hydrodynamic changes due to the Super Typhoon Rammasun in the Gulf of Tonkin (GTK). The results indicated that the typhoon strongly affects the current, water level, wave fields, and suspended sediment transport in the western coastal areas of the GTK.

This study presents the results of research on water exchange and the environmental capacities of total suspended sediment (TSS), inorganic nutrients (PO4 3- , NO3 - and NH4 + ), and heavy metals (As, Hg, Cu, Cd, Pb, and Zn) in the receiving water of the Bach Dang estuary area.

This study aims to investigate the potential use of satellite observations (MODIS reflectance) to detect the seasonal change of suspended sediment flux in the RRD region. We first extract the satellite reflectance value at the location of the station and then apply simple regression analysis to the reflectance, discharge, suspended sediment, and total sediment load on the same day.

The accelerated erosion and the sediment outflow from agricultural lands is a serious global problem. Mankind will be facing great challenges in the next few decades. The present study was undertaken to estimate the suspended sediment concentration using Fuzzy Logic (FL), Multiple Linear Regression (MLR) and Sediment Rating Curve (SRC) models for the Vamsadhara river catchment comprising of 7820 km2 Area, situated between Mahanadi and Godavari river basins in south India.

While construction of the Aswan High Dam (AHD) has stopped concurrent flooding events, River Nile is still subject to low intensity flood waves resulting from controlled release of water from the dam reservoir. Analysis of flow released from New Naga-Hammadi Barrage, which is located at 3460 km downstream AHD indicated an increase in magnitude of flood released from the barrage in the past 10 years. A 2D numerical mobile bed model is utilized to investigate the possible morphological changes in the downstream of Naga-Hammadi Barrage from possible higher flood releases.

The CGM has been gradually facing to numeric challenges of global climate change, environmental degradation and socio-economic development for the last decades. To evaluate sediment quality in the CGM, we collected 13 cores to analyze for sediment grain size, organic matter content, and trace element concentration of Cd, Cr, Cu, Ni, Pb, Zn. Results showed that trace element concentrations ranged from uncontaminated (Cd, Cu, and Zn) to very minor contaminated (Cr, Ni, and Pb). The concentrations were gradually influenced by suspended particle size and the mangrove plants.

Sediment Transport Processes and their Modelling Applications is a book which covers a wide range of topics. The effective management of many aquatic environments, requires a detailed understanding of sediment dynamics. This has both environmental and economic implications, especially where there is any anthropogenic involvement. Numerical models are often the tool used for predicting the transport and fate of sediment movement in these situations, as they can estimate the various spatial and temporal fluxes.

In response to the need for an all encompassing treatment device to deal with trash, debris (organic and non organic) solids, sediment, total suspended solids (“TSS”), metals (dissolved/particulate), nutrients (dissolved/particulate), oils, hydrocarbons, polycyclic aromatic hydrocarbons (“PAH”), and pathogenic bacterium contaminants, the City of Oceanside authorized the installation of the Modular Wetlands Device in April of 2008.

After its emission or secondary formation, the length of time airborne matter will remain suspended in the air will depend upon its density, shape and size and meteorological conditions. Suspended particles are deposited by dry deposition, either by sedimentation and gravitational settling or impaction due to atmospheric turbulence and diffusion. This latter process is characteristic of particles which undergo Brownian movement and sizes below 0.1µm.

The system of three-dimensional hydrodynamic-environmental models could simulate full advection and dispersion processes of the dissolved and particulate matter as suspended sediment and all oil phases in the realistic marine conditions. The hydrodynamic model provides temperature, salinity and current structure and water level. These variables will be used in the environmental model simulating the advection and diffusion processes for suspended matter concentration, bottom sediment thickness and all oil spill phases in the water and bottom sediment.
