“…The changing climate and the increasing incidence of extreme precipitation events with alternating long-term droughts make the management of rainwater in urban areas a topic of increasing interest [1,2]. The expansion of cities and the related increase in the sealing of areas, and thus the amount of rainwater discharged into sewage systems, disturbs the natural circulation of water in nature, contributing to lowering the groundwater level, excessive drying and erosion of soils, and increasing pollution of rivers and lakes [3].…”

“…According to the Water Framework Directive of the European Community 2000/60/EC of 23 October 2000, which establishes a framework for action in the field of water policy, associated countries are obliged to rationally use and protect water resources, in accordance with the principle of sustainable development [9]. These activities should be understood as the activity of states in areas which in their strategy aim at: (1) meeting the demand for water of the population, agriculture, and industry, (2) promoting sustainable water use, (3) protecting waters and ecosystems in good ecological status, (4) improving water quality and the condition of ecosystems degraded by human activity, (5) reducing groundwater pollution, and (6) reducing the effects of floods and droughts. Traditional drainage systems, in which rainwater is treated as sewage/waste/a problem that should be disposed of as soon as possible, do not meet the above assumptions and are perceived as unsustainable [10].…”

In recent years, as a result of intensive urbanisation, a significant increase in the surface of impermeable areas has been observed, which results in changes in the hydrological cycle of catchments. In order to counteract these changes, low-impact development (LID) solutions are increasingly being implemented in urban catchments, including bioretention systems. Taking this into account, a new bioretention drainage channel (BRC) was designed, whose main task is retention, infiltration, and pre-treatment of rainwater. The pilot laboratory tests carried out on two BRC prototypes (K1 and K2) showed that the average rate of reduction of mineral-suspended solids from rainwater was 69% and 57%, respectively, for K1 and K2. Analysing the results of the research, it was found that the bioretention drainage channel is characterised by very high efficiency in removing petroleum hydrocarbons from rainwater, and the reduction rate of these pollutants for both the K1 and K2 channels was close to 100%. In turn, hydrodynamic studies carried out on the model of the urban catchment showed that the implementation of BRCs will reduce the peak runoff by more than 82%, and the maximum flow in the sewage network by 83%.

“…Traditional drainage network inspections, the bulk of which call for professionals to go to the monitoring site, are not only time-consuming but also susceptible to various variables, such as the environment and climate. (Jato-Espino et al, 2022). It has real-time detecting technology that can gather information on sewage discharge to enhance the effectiveness of monitoring the drainage network, but the monitoring system needs manual supervision round-the-clock to identify anomalies.…”

<p>Identifying and classifying anomalies in on-line monitoring systems of drainage systems is important to reduce urban water pollution. In the context of big data, the mini-batch K-means combined with the XGBoost drainage network abnormal flow identification and classification model is proposed to precisely identify and classify abnormalities that occur in real-time updates of online drainage network data while resolving problems with subjectivity and the lack of uniform standards for classification. First, using Mini Batch K-means, the unclassified drainage network data were sorted into four categories: normal drainage, sneaky drainage, rainwater and sewage mixing, and inflow and infiltration. Next, XGBoost performs data modeling to create a model for classification and identification of drainage flow anomalies. To increase the accuracy of the model, the features were ultimately chosen based on the ranking of the importance of the features, and the model parameters were established using grid search and cross-validation. The results showed that the XGBoost Drainage Network Anomaly Classification and Identification Model can accurately identify four drainage network situations with high classification accuracy and good performance. It was also validated through the application of data from the online system monitoring points in Changsha, China, in 2020.</p>

“…Many important concepts in sustainable water landscapes in cities, which are known by different names in different countries, have appeared globally, for example: Eco-cities [5][6][7], Best Management Practices (BMPs) [8][9][10], Low Impact Development (LID) [11][12][13], Green and Blue Infrastructure (GBI) [14][15][16], Water Sensitive Urban Design (WSUD) [17][18][19], and Sustainable Urban Drainage Systems (SUDS) [20][21][22]. Based on the experience of water ecological construction in world cities, and combined with China's national conditions, the Ministry of Water Resources of China formally proposed the construction of water ecological civilizations in 2013.…”

The water ecological environment problems brought about by rapid urbanization have prompted the proposal and implementation of different approaches to urban water ecological construction, such as eco-cities, best management practices (BMPs), and low-impact development (LID). As one of the most representative urban water ecological management policies in China, the Water Ecological Civilization City (WECC) was proposed in 2013, and 105 cities were selected for pilot construction. Many studies have evaluated the effectiveness of WECC construction, but international quantitative comparison is lacking. To address this, an urban Water-Human-Health (WHH) Assessment Model, considering water resources, ecological environment, economic and social development level, and water resources utilization, was developed and applied to five WECC pilot cities in China and 10 other cities worldwide, in which mainstream urban water ecological construction modes have been used. Principal component analysis of the index values in the assessment system was used to evaluate the current status of water ecosystem health in the 15 cities, showing that Sydney, Cleveland, and Hamburg were the most advanced in urban water ecological management. The two cities with the best evaluation results (Sydney and Cleveland), and the WECC city with the highest score (Wuhan) were selected for documentary analysis of their water ecological construction documents to identify similarities and differences to inform best practice internationally for urban water ecological construction. The results showed that Sydney and Cleveland attach similar emphasis across most constituents of urban water ecological construction, while, for Wuhan, greater importance is attached to water resource management and water culture. The advantages and disadvantages of WECC construction and international experience are discussed. The WHH assessment model proposed in this study provides a new quantitative evaluation method for international urban water ecological health evaluation, which could be further improved by including an urban flood risk indicator.
