Sustainable Research on Water Quality Monitoring and Nutrient Pollution Control

Dear Colleagues,

Excessive nutrient pollution from agricultural runoff, wastewater, and industrial discharges leads to eutrophication, harmful algal blooms, and hypoxia, threatening freshwater and coastal ecosystems. These issues are further exacerbated by the complex and intensifying impacts of anthropogenic activities and climate change. This Special Issue focuses on sustainable approaches for monitoring and mitigating water pollution.

Advanced technologies like remote sensing, IoT sensor networks, environmental DNA (eDNA), and digital twins offer eco-friendly, real-time monitoring and predictive modeling of water quality. These innovations help assess nutrient dynamics, predict algal blooms, and manage hypoxia, promoting sustainable water management and ecosystem health. Machine learning and AI models, along with biogeochemical models, provide valuable insights for developing early warning systems and nature-based solutions. These tools support adaptive, policy-driven water management strategies aimed at long-term sustainability and ecosystem restoration.

The scope of this research topic includes, but is not limited to, the following (all experimental, observational, investigative, and modeling research are welcomed):

• Sustainable management of eutrophication and nutrient dynamics;
• Monitoring and forecasting of algal blooms;
• Hypoxia formation, early detection, and mitigation strategies;
• Applications of remote sensing, IoT, eDNA, etc., in sustainable water quality monitoring;
• Machine learning, AI, and digital twin applications for sustainable water systems;
• Coupled physical–biogeochemical modeling to support restoration and policy;
• Nature-based solutions and ecosystem-based management strategies.

We look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
