Special Issue Information

Dear Colleagues,

Environmental pollution prevention and reduction are essential to improving the quality of life and promoting sustainable development while protecting future resources. Water is a very precious resource in many parts of the world. Research into effective, economical, and fit-for-purpose technologies that support the characterization, treatment, and beneficial use of water are imperative to effective water management systems. The water management industry has witnessed a wave of innovation to meet the demand for effective and efficient solutions. There are also some key technologies that can drive positive change across a range of industries, with a positive environmental impact. This Special Issue aims to present research articles and review papers providing integrated approaches on methods, technologies, solutions, and application of best practices for a sustainable environment. In this regard, researchers from all over the world who study this topic and related issues are invited to contribute their work to this Special Issue to emphasize the nature of the relationship between water management technologies and environmental sustainability and give an overview of novel and multidisciplinary approaches to environmental protection, sustainable development, and a healthier way of life. In this Special Issue, original research articles and reviews are welcome, covering topics which may include but are not limited to the following: Water management technologies;Successful applications of novel research methods;Environmental problems in water technologies;Performance in water technologies;The climatic and socio-economic effects on the surrounding environment;Implementation and monitoring of policies for sustainable development. I look forward to receiving your contributions.

Under the influence of global climate change, water conservancy projects located in the high-latitude cold regions of the world are facing severe challenges. This study addresses the contradiction between water supply stability and ecological flow during the dry season in cold regions. Taking Linhai Reservoir as the core, it integrates the HEC-RAS hydrodynamic model with multi-source data such as basin topography, hydro-meteorological data, and water conservancy project parameters to construct a multi-scenario water supply scheduling model during the dry season. The aim is to provide scientific recommendations for different reservoir operation strategies in response to varying frequencies of upstream inflow, based on simulations conducted after the reservoir’s completion. Taking into account winter runoff reduction characteristics and engineering parameters, we simulated the relationships between water level and flow, ecological flow requirements, and urban water shortages. The results indicate that in both flood and normal years, dynamic coordination of storage and discharge can achieve a daily water supply of 120,000 cubic meters, with 100% compliance for the ecological flow rate. For mild and moderate drought years, additional water diversion becomes necessary to achieve 93.5% and 89% supply reliability, respectively. During severe and extreme droughts, significantly reduced reservoir inflows lower ecological compliance rates, necessitating emergency measures, such as utilizing dead storage capacity and exploring alternative water sources. The study proposes operational strategies tailored to different drought intensities: initiating storage adjustments in September for mild droughts and implementing peak-shifting measures by mid-October for extreme droughts. These approaches enhance storage efficiency and mitigate ice blockage risks. This research supports the water supply security and river ecological health of urban and rural areas in Mudanjiang City and Hailin City and provides a certain scientific reference basis for the multi-objective coordinated operation of reservoirs in the same type of high-latitude cold regions.
