Feature Articles
Hydro international offers professionals the opportunity to contribute to any forthcoming issue in a practical and informative way, taking the editorial theme into account.

  • No marketing lingo
  • No mathematical formulas
  • Please include a short bio of the (up to 3) main author(s)
  • Please include portrait images of the (up to 3) main author(s)

All material should be submitted in as complete as possible, and by email, text separate from illustrations - which means that illustrations should be added as the original files. Contributions and any further queries may be directed to Joost Boers, content manager.

Planning ahead - we assign papers to an issue once they are received, reviewed and approved for publication. In general this will be happening in order of approval. If you aim to publish in a particular issue, please allow more time (two months before the deadline) and let us know your intentions so we can coordinate the planning of your paper.

All articles for publication are subject to review by our publishing director, Durk Haarsma. After acceptance articles will be edited and checked for English language style and grammar. All material submitted to the publisher Geomares Publishing and relating to Hydro international will be treated as unconditionally assigned for publication under copyright, subject to the editor's unrestricted right to edit and offer editorial comment.
