Feature Papers of Hydraulics and Hydrodynamics

Dear Colleagues,

Water systems (WS) transport water for hydropower production, drinking and irrigation water networks. Water systems are used in process industries and rivers from water sources, water treatment plants, reservoirs created by dams, tanks and retention ponds in sustainable urban drainage systems (SUDs) in order to satisfy all types of water–energy–food–environment nexus customers. Water conveyance solutions which transfer water for drinking, irrigation, waste, storms, rivers, energy production, storage and industries from an intake to final users can be carried out using integrated solutions to better suit the main efficiency purposes. These important infrastructures are becoming a dynamic environment, where advanced tools and algorithms, new technologies and the best practices should be integrated and implemented with the ambition to increase the systems’ reliability, the ability to adapt to climate change, the refurbishment of existing infrastructures with eco-design solutions and the best operations under safe and reliable conditions towards the greatest effectiveness, sustainability and management. Monitoring systems (MSs), control technologies (CTs), management strategies (MSs), water and energy savings (WESs), eco-innovative solutions (EISs), mathematic algorithms (MAs), computer modelling (CM) and decision support management systems (DSMSs) have to be upgraded in order to obtain technical, economic and environmental benefits both in terms of research, technology implementation and engineering applications.

Consequently, a sustainable water–energy–food–environment nexus (WEFEN) has increased in terms of its water and energy efficiency; interdependency between water, energy and food resources; as well as its relationship with technological development and management policies for food production and processing and environmental integration towards smart water grids (SWG), digital twins and new hybrid water–energy solutions. This is a new path for smart technology, resource management and sustainable water infrastructure developments in the near future to face climate and demanding challenges, as well as energy and digital transitions.

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-anonymized 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.
