Water quality in wetlands plays a huge role in maintaining the health of the wetland ecosystem. Water quality should be controlled by an appropriate water allocation policy for the protection of the wetlands. In this paper, models of rainfall/runoff, non-point source pollution load, water quantity/quality, and dynamic pollutant-carrying capacity were established to simulate the water quantity/quality of Xixi-wetland river network (in the Taihu basin, China). The simulation results showed a satisfactory agreement with field observations. Furthermore, a ‘node-river-node’ algorithm that adjusts to the ‘Three Steps Method’ was adopted to improve the dynamic pollutant-carrying capacity model and simulate the pollutant-carrying capacity in benchmark years. The simulation result shows that the water quality of the river network could reach class III stably all year round if the anthropogenic pollution is reduced to one-third of the current annual amount. Further investigation estimated the minimum amount of water diversion in benchmark years under the reasonable water quantity-regulating rule to keep water quality as class III. With comparison of the designed scale, the water diversion can be reduced by 184 million m3 for a dry year, 191 million m3 for a normal year, and 198 million m3 for a wet year.

In this paper, Zhushan Bay watershed to the northwest of Lake Taihu was selected as the research area. Taking the developed river-lake connectivity and frequent exchange of pollutants into consideration, we put forward a calculation method of water environment carrying capacity (WECC) for river network based on multiple objectives of water quality reaching standard in river environment function zones and control sections, concentration profile constraint of sewage outlet. According to the proposed method, we calculated the watershed WECC, assigned to each control unit, and quantitatively analyzed the reductions and reduction rate of pollutants under the condition of total amount of each pollutant of control unit reach water quality standards. The results showed that: The pollution loads of each pollutant in Zhushan Bay watershed were greater than WECC. The reduction of COD, NH3-N, TN and TP is 834.4 tons, 226.1 tons, 724.8 tons and 108.9 tons, and the reduction rate of COD, NH3-N, TN and TP is 13.8%, 36.5%, 55.2% and 73.4%, respectively. This paper plays a guiding role in the research of total amount control of river network in Zhushan Bay watershed, and provides important references for total amount control of similar river-lake region.

Abstract In eastern China, the rural river network area (RRNA) is an anthropic active area characterized by its rapid economic development and high gross national product. However, the water environmental pollution in these areas is increasingly severe, which has greatly hindered its sustainable development. Especially, the frequent interactions between surface/groundwater (SW-GW) have intensified the pollution migration and transformation in RRNA. Therefore, an integrated remediation in rural river network area project (IR-RRNA) has been launched, funded by the Ministry of Science and Technology of the People’s Republic of China, to realize the integrated remediation of SW/GW and soil in RRNA. The IR-RRNA (2019–2022) will apply the related interdisciplinary and methodological knowledge to elucidate the transportation and transformation of pollutants in water and soil during SW-GW interaction, and develop key remediation technologies of surface water, groundwater, and soil suitable for the RRNA. By this way, we attempt to realize the remediation technologies integration for surface/groundwater and soil in RRNA and implementing application demonstration. Meanwhile, a technical guideline will be compiled for the integrated remediation suitable for the RRNA. This project is conducive to addressing the urgent environmental problems of RRNA, and promoting the rural economic revitalization and ecological environment optimization.
