Dear Colleagues,

Urban water systems (UWSs) are the most essential part of public infrastructure and face multiple challenges related to future uncertainties in providing a more sustainable and resilient service. UWSs typically include water collection, storage, treatment, transport (via tunnels and pipelines), sewer, and drainage facilities.

Because of the large scale and complexity of urban water systems, water behavior prediction through accurate computer modeling and analysis is essential, and predicted results should be reflected in actual planning, design, and operation. The modeling procedure and results can be varied, dependent upon the implementation model dimensions (1D, 2D, and 3D), governing equations, calibration and verification techniques, simulation scenarios (normal/abnormal), and type of observed data.

The goal of this Special Issue is to concentrate on emerging topics of urban water systems modeling and analysis, especially in water supply and drainage networks. Topics of interest include but are not limited to:

• New hydraulic, hydrologic, and water quality modeling and analysis techniques in UWSs;
• Optimal design of urban water supply and drainage systems, including water network partitioning;
• (Dynamic) calibration and verification issues for real-time modeling and data analysis;
• UWSs response and recovery under catastrophic failure events;
• Big data and analytic challenges for the management of UWSs using IoT-based measured data;
• Innovative metrics for resilience computation in UWSs;
• Rainfall–runoff modeling in UWSs under climate change and urbanization;
• Actions to protect UWSs from accidental and intentional contamination;
• Optimization algorithms and artificial intelligence base techniques for dealing with large networks (any civil infrastructure can be covered).

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. Applied Sciences 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 2400 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.
