Special Issue Information
Dear Colleagues,
Flow and sediment transport are becoming increasingly important, yet complex, disciplines in civil engineering due to population growth and climate changes. Most water projects need to consider hydraulic, hydrological, and sedimentation processes that may impact project design. Numerical modeling has been widely used for understanding various physical processes and providing the data needed to make the project decisions. For project impact studies, numerical modeling is probably the only mean to gain an understanding of the altered state. In the past, one-dimensional (1D) flow and sediment models have been widely used, which made various simplifying assumptions. In recent years, multi-dimensional (MD) models, primarily two-dimension (2D) and three-dimension (3D), are gaining popularity in simulating flows and sediment transport processes. MD models are more reliable and accurate than the 1D ones; their use, however, is hampered by various factors. In particular, guidelines are lacking regarding model input parameters and when to use MD modeling. This Special Issue, therefore, aims to gather high-quality papers that contribute to the current state-of-the-art in using MD flow and sediment models.
Proposed topics may refer but are not limited to the following: the development of MD models, the application of MD models to shed light on model accuracy and reliability, and MD modeling guidelines in comparison with 1D models. The spatial scale of MD modeling may range from small-scale streams to large-scale watersheds, and temporal scale may be either constant-flow, event-based, or long-term.
Submitted contributions will go through a peer review process performed by independent reviewers. Original studies of model development and/or improvement, case studies, and review papers are invited for publication in this Special Issue.

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.
