“…According to the DPSIR framework, the indicator system for urban river health evaluation is constructed. According to the related research findings [17,[28][29][30][31][32][33], the 24 evaluation indicators are determined in this study. Among them, the indicators (D1-D3) of the driving force subsystem are mainly selected from the situation of regional urbanization.…”

As the key source for freshwater resources, urban rivers are essential for human survival and urban socio-economic development. Recently, the functions of urban rivers have been damaged by increasing human activities. A better understanding of the health state of urban rivers is the basis of sustainable urban planning. To this purpose, this research took the Jinshui River as a research area. An indicator system for urban river health evaluation was first established using the driving force-pressure-stateimpact-response (DPSIR) framework. The health state of the Jinshui from 2008 to 2017 was then assessed based on the urban river health index, which was calculated by the improved fuzzy matterelement extension model. The results show that the overall health status of the Jinshui has improved, from its unhealthy state in 2008-2016 to a sub-healthy state in 2017. Corresponding response measures have achieved certain results, which have led to an improvement in the health state of the river. However, its health still faced many problems, including pressure from a rapid urbanization rate and population density, a large amount of sewage discharge, and serious water pollution. In general, the health of the Jinshui was still on the low side. Therefore, to ensure sustainable water environment in the region, it is necessary to further govern the water environment and improve the health status of urban rivers. This research can help government easily understand an urban river's health state and formulate effective measures in the future.

Urban rivers are valuable elements of urban ecosystems and play a key role in urban socio-economic development. Unfortunately, the functional integrity of urban rivers is being threatened by extensive human activities associated with the social development. Urban river health evaluation is important, as it may provide policy makers with information that is fundamental for river governance and the protection of urban ecosystems. To this purpose, we first constructed an urban river health assessment index system based on the pressure-state-response (PSR) framework. Secondly, we developed an urban river health index (uRHI) using the improved fuzzy matter-element extension assessment model. Finally, we used the uRHI to assess the health state of the Jialu River from 2008 to 2017 in Zhengzhou City, China. The results indicate that the health state of the Jialu River was improved from an unhealthy state in 2008 to a sub-healthy state in 2017. The pressure, state, and response subsystems developed towards a healthier state from 2008 to 2017, thanks to the implementation of a number of actions by the local government. However, the overall health status of the Jialu River is still relatively low. The Jialu River also faces several pressures, such as substantial Chemical Oxygen Demand (COD) emissions and sewage discharge. This paper concludes that it is necessary to further strengthen the health management of the Jialu River and the protection of Zhengzhou's water environment.

“…While high phosphate-P concentration has been reported by [13] be a challenge in the study catchment (United Utilities, personal communication, 2019), river classification based on the EU WFD indicators may not indicate other contributory factors such as discharge, slope, altitude and catchment area as shown by the biological and environmental analysis. Therefore, a framework which assesses the river catchment on a case by case basis could help in effective classification and catchment management in the local context [23].…”

Communities of benthic macroinvertebrates obtained from a river catchment impacted by point source pollution were investigated from March 2013 to April 2014. The main purpose of this study was to describe the taxon richness of benthic macroinvertebrate communities obtained at upstream and downstream of a wastewater treatment works and combined sewer overflows, assess water quality and to determine major physicochemical variables that affect the distribution and richness of benthic macroinvertebrate communities. The biotic index Whalley Hawkes, Paisley and Trigg revealed distinction between the sites upstream of the wastewater treatment works from the downstream sites. Between and within sampling locations, the dominance of certain taxonomic groups was recorded including Oligochaete, Baetidae and Chironomidae. Predominant in the river were insects which constituted 72% of the overall benthic invertebrate communities followed by Oligochaeta (28%). Distribution of benthic macroinvertebrate communities was not associated with sewage variables but related more with altitude, catchment area, slope and discharge. Altitudes range from 31 to 140 m. The sites at higher altitude had better quality compared to the lower sites and therefore suggests that altitude could provide a spatial proxy for anticipated future ecological changes in the river over time. Classification of the river based on the European Union's Water Framework Directive indicated that the river had moderate ecological status.
