Ø  Nitrogen Transformation Mechanism in the Confluence Area of Taihu River Networks Based on the Response of Microbial Community to Hydrodynamic Spatial Differences, funded by National Natural Science Foundation of China (Grants No. 52100175).

        •The confluence of rivers is an important part of the river network. The complex hydrodynamic conditions in the confluence area will affect the migration and transformation of nitrogen, and will be connected through the river network and water system, further affecting the distribution of nitrogen pollution in the basin. In this study, the problem is the influence of the river network of plains and rivers on the migration and transformation of nitrogen. It is planned to take the Taihu river network as the research area and the nitrogen conversion process as the research object, through methods such as high-throughput sequencing, molecular biological analysis, dynamically adjustable hydraulic model and hydrodynamic water quality model. First, study the spatial differences of river network hydrodynamics and their effects on the distribution characteristics of microbial communities under different conditions of water volume, water level, intersection angle, river bed width and depth ratio. Identify the dominant driving factors for the evolution of the nitrogen cycle microbial community under confluence hydrodynamic conditions. Based on the physical model test, the environmental response mechanism of the structure and function of the nitrogen cycle microbial community under dynamic water conditions and the degradation process of nitrogen pollutants under the action of this mechanism are studied. Finally, combined with the gene center model, the law of nitrogen transformation in the plain river network confluence area under the coupling effect of diffusion-mixing-adsorption-degradation is analyzed. Establish the self-purification equation of nitrogen pollutants in the junction area under multi-mechanism coupling, and embed it in the EFDC open source code. This research provides scientific support for pollution prevention and control, environmental governance and comprehensive management of river networks in the basin.

Ø  The Influence of River Morphology on Material Migration and Transformation: A Case Study of Branched River Channels, by the Fundamental Research Funds for the Central Universities (Grants No. B240201187).

        •The bifurcated river channel is a widely existing river form in the plain river network. Analyzing the driving mechanism of microbial nitrogen transformation in the diversion area of the bifurcated river channel and the evolution characteristics of hydrological conditions in the corresponding antibiotic basins from a microscopic perspective provides a scientific basis for the total control of typical conventional pollutants and new pollutants. Through field sampling, laboratory experiments and numerical simulation studies, based on theories such as ecology, biogeochemistry, DNA sequencing and mathematical models, Research on hydrodynamic zoning and microbial nitrogen transformation in the diversion area of the branch river, the distribution and ecological risk of antibiotics in the sediment of the diversion area of the branch river based on the hydrological characteristics of the basin, and the division of water body control units in urban small watersheds based on multi-element index assessment have been carried out. Starting from the total quantity control and the division of prevention and control units in the water environment management of urban rivers, the biogeochemical processes of pollutants caused by river morphology are refined, and the water ecological functions and characteristic index system in the division of prevention and control units in the basin are comprehensively considered. Taking the typical bifurcated river channel morphology as an example, the hydrodynamic zoning of the diversion area, the distribution and ecological risks of microbial nitrogen transformation and antibiotics in the sediments of the diversion area were studied, providing a basis for the correction of the total discharge limit of conventional pollutants in the affected areas of special river forms and the prevention and control of ecological risks of characteristic pollutants. Based on a comprehensive consideration of indicators such as water resources and water environment, the weights for the division of basin prevention and control units should be strengthened in terms of water ecological service functions, water ecological community structure, ecological diversity, etc., to provide management basis for the protection of urban river water environment and water ecological restoration.
