Special Issue Information

Dear Colleagues,

The mixing of river freshwater with highly salty seawater in estuaries along with river sediment transport toward the sea and tidal landward sediment transport make estuaries one of the most complex hydrodynamic environments. Adding the influences of human activities, like dike constructions, dredging, ship navigation pollution-end erosion, and finally, sea-level rising that leads to coastal urban flooding, all are approving the necessity of a series of studies on "The Integrated Rivers and Estuaries Interactions and Hydrodynamics". This Special Issue will publish the latest contributions in this field as research articles. Researchers from both academia and industry are welcome to submit original articles that advance state-of-the-art research in estuary hydrodynamics.

Topics include but are not limited to the following:

  • Estuary salt intrusion hydrodynamics
  • Coastal urban flooding, sea-level rise and estuary morphology
  • Estuary and riverbank protection from ship-induced waves
  • Navigation and river-estuary pollution
  • River-estuary sedimentation and dredging

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. Journal of Marine Science and Engineering is an international peer-reviewed open access monthly journal published by MDPI.

River confluences are the key features of the drainage basins, as their hydrological, geomorphological, and ecological nature strongly influences the downstream river characteristics. The river reaches near the coastal zones, which also makes them under the influence of tidal currents in addition to their runoff. This causes a bi-directional flow and makes the study of confluences more interesting and complex in these areas. There is a reciprocal adjustment of flow, sediment, and morphology at a confluence, and its behaviors, differ greatly in tidal and non-tidal environments. Existing studies of the river junctions provide a good account of information about the hydrodynamics and bed morphology of the confluent areas, especially the unidirectional ones. The main factors which affect the flow field include the angle of confluence, flow-related ratios (velocity, discharge, and momentum) of the merging streams, and bed discordance. Hydraulically, six notable zones are identified for unidirectional confluences. However, for bi-directional (tidal) junctions, hydrodynamic zones always remain in transition but repeat in a cycle and make four different arrangements of flow features. This study discusses the hydrodynamics, sediment transport, morphological changes, and the factors affecting these processes and reviews the recent research about the confluences for these issues. All of these studies provide insights into the morpho-dynamics in tidal and non-tidal confluent areas. Full article
