Special Issue Information
Dear Colleagues,
Non-Newtonian fluids, whose flow properties are not described by a single constant value of viscosity, are ubiquitous in nature. Such fluids are most commonly characterized by a non-linear relationship between stress and strain, yield stress, or time-dependent viscosity. Rheological complexity entails, in turn, solving non-linear mathematical problems that are far more challenging than those involving Newtonian fluids. Similar challenges are faced at the experimental level, where physico-chemical aspects and rheometry become paramount. For environmental flows, these issues are often coupled with the inherent parametric uncertainty typical of natural settings.
This Special Issue is open to papers advancing knowledge of non-Newtonian flows in natural fluid systems, both above and below ground, or showing innovative applications. Analytical, numerical, and experimental approaches are equally welcome. Potential topics include but are not limited to open-channel flows (including regime transitions, propagation phenomena, and stability), debris and mud flows, gravity currents both in the viscous and inertial regime, and turbulence modeling. As to the subsurface environment, this call welcomes analyses (at the Darcy scale) and case studies dealing with both porous and fractured media and pertaining to fracking, EOR applications, the migration of pollutants, wastes and drilling fluids, and the flow of complex fluids acting as carriers for remediation agents, to name a few.

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.
