Special Issue Information

Dear Colleagues,

The hydrodynamics of flowing and stagnant water—natural or artificial—studies the mechanics of the mixing and stratification processes and the mechanisms of transport and degradation of pollutants in the environment. In general, the quantities of interest are mass, momentum, and heat, where mass can be represented by any pollutant. The hydrodynamics and water quality of rivers and lakes in response to human activities and extreme weather events (e.g., draughts, floods) are important subjects that remain in need of deeper understanding.

The aim of this Special Issue is to address environmental problems (e.g., natural, and anthropogenic stressors) for surface aquatic environments, such as rivers, lakes, and reservoirs, in direct correlation with the use of water for various purposes. Water movement in these systems, as well as the disturbances on the system (e.g., extreme hydroclimatic events), influences its physical–chemical characteristics (temperature, dissolved oxygen regime, nutrient concentrations, etc.) and the distribution of pollutants, sediments, or aquatic organisms; therefore, there is a need to investigate and propose a form of targeted management (e.g., remediation measures).

Therefore, directions to be approached can be related to both the discussion of the fundamentals of hydrodynamic in surface waters, such as rivers, lakes, and reservoirs, and the management of surface water systems, which requires technical abilities. To this end, this Special Issue aims at providing an integrated approach of hydrodynamics, sediment transport, pollutants transport and transformations, water quality, and eutrophication in surface water systems.

Excess sediment and nutrient losses from intensifying agriculture degrade water quality and boost plant growth. The relationship between circulation patterns, spatial water quality degradation, and water hyacinth infestation is not adequately studied. The objective of this study is, therefore, to investigate the effect of lake circulation patterns on sediment and nutrient distribution and its implication on the spread of water hyacinth in a tropical lake. This study was carried out in Lake Tana, the largest freshwater lake in Ethiopia, where sediment and nutrient concentrations are increasing, and water hyacinths have become a challenge since 2011. The lake circulation pattern was simulated by the Delft3D model based on a bathymetry survey, discharge, and meteorological forcings. To predict the transport path of sediments and dissolved nutrients, an inert tracer was released in the four main river inlets of the lake. Observed lake water level measurements were used to validate the model. Our results show that the lake circulation pattern could explain the transport path of sediment and nutrients and the location of the water hyacinths found in the northeast of the lake. Sediments and nutrients from the largest river, Gilgel Abay, in the southeast of Lake Tana, flow through the two outlets nearby with little sediment deposition due to the relatively short retention time. The phosphorus-rich sediments of the 24 h at 105 °C remaining three main rivers joining the lake at the north and east are transported to the northeast. Thus, the management and control of water hyacinths should focus on the northern and eastern catchment areas of Lake Tana. Full article
