The temporal variability of hydrological variables in the Guadalquivir estuary was examined during three years through a real-time remote monitoring network (RTRM). The network was developed with the aim of studying the influence of hydrodynamical and hydrological features within the estuary on the functioning of the pelagic ecosystem. Completing this data-gathering network, monthly cruises wer...

An increase in the intensity and frequency of extreme events is predicted to occur as a result of climate change. In coastal ecosystems, hurricanes and flooding can cause dramatic changes in water quality resulting in large mortality events in estuarine fauna. Facultative migration behaviors represent a key adaptation by which animals can evacuate ecological catastrophes, but remain poorly stud...

Maintaining low nitrite concentrations in aquatic systems is a major issue for stakeholders due to nitrite's high toxicity for living species. This study reports on a cost-effective and realistic approach to study nitrite dynamics and improve its modelling in human-impacted river systems. The implementation of different nitrifying biomasses to model riverine communities and waste water treatmen...

In order to simulate the long-term (months-years) median Escherichia coli distributions and variations in the tidal Scheldt River and Estuary, a dedicated module was developed for the Second-generation Louvain-la-Neuve Ice-ocean Model (SLIM, www.climate.be/slim). The resulting model (SLIM-EC2) presents two specific and new features compared to the older SLIM-EC model version. The first is that ...

In order to understand the distribution of elements in the environmental samples, surface seawater and sediment samples collected from the Saemangeum region of western coast of Korea were analyzed for their concentrations of major and trace elements. Dissolved heavy metal concentrations except for Cd were highest in inner part of the Saemangeum dike and in the Geum River Estuary. Riverine disch...

A major challenge in palaeohydrology is the extraction of continuous palaeoflood information from geophysical records. A high-resolution sediment core off the Minjiang estuary area in the Taiwan Strait, SE China, records the sedimentation history from approximately 1660 to the present. The alkane ratio C31/C17, a classic organic geochemical indicator of terrestrial/aquatic matter, peaks in the ...

The Port of Seville is an inland port located in the Guadalquivir River in the south of Spain and it is the unique Spanish inland port. Our research is focused on the simulation of the freight transport process beginning with the movement through the whole estuary of the river and finishing with the vessels arriving to the port dependencies, where the logistic operators’ load and unload process...

The Columbia River discharge plays a central role in North-East Pacific Ocean coastal ecosystem dynamics. A model is developed to predict non-stationary surface-salinity time-series in the North Pacific Ocean off-shore the Columbia River. The model takes wind velocities and Columbia River discharge as inputs only. Wind velocities are converted to smoothed wind stresses which are then integrated...

Freshwater input to estuaries may be greatly altered by the river barrages required to meet human needs for drinking water and irrigation and prevent salt water intrusion. Prior studies have examined the salt plugs associated with evaporation and salt outwelling from tidal salt flats in single-channel estuaries. In this work, we discovered a new type of salt plug formation in the multi-channel ...

The estuary of the Danshuei River, a hypoxic subtropical estuary, receives a high rate of untreated sewage effluent. The Ecopath with Ecosim software system was used to construct a mass-balanced trophic model for the estuary, and network analysis was used to characterize the structure and matter flow in the food web. The estuary model was comprised of 16 compartments, and the trophic levels var...
