Dear Colleagues,

Lake is a key drinking water source for municipal purposes; however, eutrophication has seriously deteriorated lake water quality worldwide over the years. This is typically reflected in the phenomena of algae bloom and cyanobacteria bloom. In order to restrain eutrophication, treatment technologies and integrated control system have to be proposed and implemented, with the main focus on cutting down algal biomass, reducing suspended solids, increasing water transparency, and restoring healthy lake ecosystems. Particularly for shallow lakes with a high nutrient utilization rate and consequent high primary productivity, inhibiting algal bloom becomes a core task. Moreover, global warming is believed to be another major cause for eutrophication, as the untimely rising of water temperature could lead to the booming growth of algae and cyanobacteria. In summary, from the perspective of accurate early warning and efficient control of eutrophication, evaluation of measures taken in reducing point source and non-point source nutrient loads must be carried out, together with continuous monitoring and in-depth mechanism studies.

This Special Issue aims at gathering and sharing papers about the most advanced knowledge and successful experience on mechanism exploration, control technologies, and evaluation systems of eutrophication. Hopefully, this initiative will contribute to the mitigation of eutrophication and ensure water security globally.

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.
