Modelling of hydrodynamics and cohesive sediment transport in Tanshui River estuarine system, Taiwan [PDF]

Marine Pollution Bulletin, 2002
A laterally averaged two-dimensional numerical model is used to simulate hydrodynamics and cohesive sediment transport in the Tanshui River estuarine system. The model handles tributaries as well as the main stem of the estuarine system. Observed time series of salinity data and tidally averaged salinity distributions have been compared with model ...

A coupled hydrodynamic (HEC‐RAS 2D) and water quality model (WASP) for simulating flood‐induced soil, sediment, and contaminant transport

Journal of Flood Risk Management, 2021
Increased intensity and frequency of floods raise concerns about the release and transport of contaminated soil and sediment to and from rivers and streams.

Colloidal transport of heavy metals in low‐advective‐velocity environmental systems: Reactive transport model on biogeochemical and hydrodynamic impacts

Vadose Zone Journal, 2022
Abstract In this study, the impact of colloid facilitated transport of heavy metals on the overall biogeochemical processes is demonstrated in example Lake Coeurd'Alene sediments. Release and transport of heavy metals (Pb and Zn) on initially sorbed colloidal Fe (hydr)oxide minerals are compared with immobile ...

Assessing flooding impact to riverine bridges: an integrated analysis [PDF]

Natural Hazards and Earth System Sciences, 2022
Flood events are the most frequent cause of damage to infrastructure compared to any other natural hazard, and global changes (climate, socioeconomic, technological) are likely to increase this damage.
