Special Issue Information

Dear Colleagues,

This Special Issue focuses on the pollution mechanisms and source apportionment of typical pollutants in various water systems within a watershed, including rivers, lakes, and groundwater. It aims to provide a comprehensive and in-depth academic exchange platform for researchers of water environments. The content of this Special Issue will cover water quality assessments, the pollution mechanisms of typical pollutants, the migration and transformation processes of pollutants, source tracking of pollution, the development and application of water quality models, as well as ecological impact assessments caused by water quality changes. These research findings will not only help us more accurately understand the dynamics of water quality within the watershed, but also provide a solid theoretical basis for formulating scientific and effective water quality protection measures. We sincerely invite water environment scientists, engineers, policymakers, and water resource managers to participate in this Special Issue. Our goal is to promote comprehensive exchanges across disciplines and fields and jointly advance the process of water environmental protection and sustainable development. We look forward to your active contributions to the academic developments and practical applications in this field.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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.

Reliable identification of river hydrograph separation is crucial for prioritizing water source areas to be protected from pollution. A field study was carried out in a hilly catchment with diverse land uses, located in Southwest China. A novel water-tracing method, combining the ratio of two conservative fluorescent components of dissolved organic matter, two ion ratios, and oxygen-18, was proposed for river hydrograph separation with MixSIAR. During a rain event with the longest preceding no-rain period, a set of four tracers were found to be applicable to drainage areas with diverse land uses. Notably, a drier antecedent soil moisture condition could favor the occurrence of more tracers qualified for distinguishing multiple water sources of river flow. Full article
