Conflict of Interests

But he that filches from me my good name/Robs me of that which not enriches him/And makes me poor indeed. - Othello, Act 3 Scene 3

To be in a conflict of interest, or even appearing to be so, damages reputations. CHI's reputation, and those of our employees, authors, editors and reviewers are important to us. They reflect our brand and the way we do business.

The possibility of a conflict of interest arises when one person or organization, or an individual or entity related to them, receives a benefit from another such that the recipient’s objectivity or autonomy regarding the benefactor may be questioned.

At CHI we are committed to publishing the results of high quality, original research. We believe that conflict of interest is best avoided by openness and transparency. To this end we expect authors to acknowledge the support and benefits they have received for their work. We expect our editors and reviewers to recuse themselves if they have any relationship with an author or business that may influence their judgment.

We also expect authors to fully acknowledge the sources of financial support for work or research that they have completed. This support includes not only grants or other funding, but also donations of materials or time benefitting the researchers.

Completed Papers

Your correctly-formatted paper must be submitted as an MSWord file, in finished form (complete with all figures etc.) using the CHI Paper Template, through the JWMM Managment Site. Be sure to include your completed transfer of copyright and Author Checklist with your submitted paper (see information below).

Review process

The review process in brief

Prior to sending the submission to Review, the Journal Manager will redact the paper and conduct a Similarity and Plagiarism check using the software CrossRef Similarity Check by iThenticate. Once the paper is determined to be an original submission, a formal decision to proceed to review will be made and the submission will be assigned to an Editor. A member of the Editorial Board will usually review the article themselves and solicit at least one other external reviewer. An online consultation session is opened with the reviewer(s) once two reviews have been received, with any outstanding reviewers prompted to submit their review and join the discussion. The Reviewing editor will make a decision whether to proceed with publication and draft a decision letter, with input welcome from the other reviewer(s). A Senior editor is available at each stage to provide guidance and oversight of the process as a whole. Our aim is to provide clear and decisive instructions to authors, so that they know what they need to do to get the article published. If a revision is requested, the decision letter will usually include a single set of instructions; the full reviews in this case are not sent to the authors. If the decision is that the article cannot be revised in a reasonable time frame for publication in The Journal of Water Management Modeling and must therefore be rejected, the letter will usually include the full reviews, with the reasons clearly explained.

Author Checklist

While preparing your paper for CHI’s Journal of Water Management Modeling, there are many instructions and requirements. Our editors and contributors are proud of this high quality peer reviewed journal, and to maintain our standards and control our publication costs, we all rely on our authors to produce quality manuscripts.

There is, unfortunately, a lot to remember, and your paper must comply with these requirements. This checklist is to help you ensure that you've covered the various points.

Your paper will be peer reviewed on value, originality, readability, language, mechanics, and freedom from commercialism/personalities. Consider these attributes as you plan your paper.

Please include the completed form with your paper submission, follow this link to download the full Author Checklist.

Journal Paper Template

Your paper must be formatted using the CHI Paper Template. Papers that do not use this template, will be returned to the author.

Here is a link to a video illustrating how to use the CHI Paper Template.

Simply open the template file as you would a normal Word file and immediately save it as "CHI paper (your last name).doc". This is your working copy. In your working copy of the file, replace the contents with your own paper. Please follow this link to download the CHI Paper Template.

If you are not used to working with Styles in Word, you will be surprised at how easily they can be employed. First, we suggest you expand the Style menu from the Home toolbar. Then you just place your cursor in the text (e.g. on a sub-heading) and select the appropriate style, e.g. "CHI Subhead" or "CHI Paragraph A". Each Style in the menu is displayed so that you can see the end result. Styles apply to paragraphs so every hard return requires you to employ a different style.

The paper template has the correct margins in place, and you must use the provided styles (all starting with "CHI" in the Styles menu - please ignore the default styles). The document you saved as a sample file illustrates the correct use of the styles. All figures and tables must fit within the page size constraints, and their contents must be clearly readable. Moreover, figures must be legible and useful to the reader when printed in black and white in the size available.

Note: pasting content from other documents will more than likely import styles into the provided paper, which may prove problematic to you (and later, for us). It is strongly recommended that you move your content to Microsoft Notepad before pasting it into the provided paper. This will strip out all formatting data and provide a much cleaner and efficient working environment in the provided paper. To do this simply copy and paste your content into the Notepad application, then copy and paste from the Notepad application to the provided MS Word paper.

Details

Title: Use style CHI Paper Title A. Keep it short. (125 characters including spaces is the absolute maximum).

Authors: Use style CHI Author A. Include only the author(s)' names (full first names) and follow the grammar of the author line in the template. Authors' contact information is listed in the endmatter of the paper, and we ask you to provide this information for at least one author at the end of your paper. Provide as much detail as you wish [names, PE/P.Eng, company, address, tel, email]. Do not include this information in the Author section of your paper.

Margins: The correct margins are set in the paper template and should not be adjusted.

Case: Use lower case throughout (except of course for initial capitals and acronyms).

Text: Use style CHI Paragraph A for the normal paragraphs in the book (paragraphs will be indented). Use style CHI book Non-indent A for the first paragraph in each subsection (i.e. this paragraph is not indented).

Abstract: A short, introductory paragraph (Abstract) should precede your first heading. Thereafter, distinguish heading levels by using the styles and numbering scheme as follows (see sample paper for reference):

Subheadings: The template includes styles for three subheadings, based on the level. Use Style Subhead 1 A to introduce each section. It should be written as follows: 1 Introduction (no punctuation). For level two subheadings, use Style Subhead 2 A, and written as follows: 1.1 Background (for example). For level three, we do not number the subheading. Use Subhead 3 A in this case.

Stress/Quote: All emphasis/quotations should be in italics. No underlining, bold, uppercase or quotation marks please.

Equations: Use style CHI Equation A. Equations should be numbered sequentially in parenthesis (), on the right. Use a single tab between the equation and the equation number (the tab spacing is set by the style). Center the equation on the line by using spaces before the equation (tabs or the center alignment feature will not work). Equations must be in Microsoft Equation format.

Tables: Here is a link to a video illustrating how to add tables to your paper. The built-in table style Table Simple is used to format the table and the style CHI Table Contents A is used to format the text within the table. Tables must fit within the set margins (see above). Tables should be slightly narrower than the page width if possible, and centered. Portrait orientation is preferable. (In extreme cases, a table can be split between two facing pages in either landscape or portrait orientation). Tables must be in Microsoft Word Table format. (No other table editors are acceptable).

Table captions: Use style CHI Caption A. Table captions appear above the table and should not be part of the table, but should be separate text. Captions should (a) start with the table number, (b) be in sentence case, and (c) end with a period.

Figures: Use style CHI Blank A. Figures must fit within the set margins. Figures should be slightly narrower than the page width if possible, and centered. Portrait orientation is preferable. Figures should not have borders, should not be reversed image (light lines on dark background), and should not use bold fonts. Please keep the original tiff, gif or jpg for each figure on hand, in case the editor asks for a figure to be adjusted. Please see the points below for figure/illustration formatting requirements:

Figure captions: Use style CHI Caption A. Figure captions appear below the figure, and should NOT be part of the figure, but should be separate text. Captions should (a) start with the figure number, (b) be in sentence case, and (c) end with a period.

Figure formatting requirements

Here is a link to a video illustrating how to add figures to your paper.

If figures are in vector or metafile format, then all embedded fonts and symbols must be common true-type Arial or Times New Roman fonts. NB Please ensure that you do not use ESRI Geometric Symbols in any of your graphics.

Figures should be a single graphic object in a standard format (.JPG, .PDF, .TIFF, .GIF) that is at least 700 pixels wide. Please do not use .PNG or low-resolution screenshots.
Image must be 300dpi or higher and fit into either:
- Vertical (portrait) orientation: 4.5" width max (and anything up to 6.75" height max), or
- Horizontal (landscape) orientation (i.e. sideways on the page): 7.0" width max and anything up to 4.25" height max).
Do not include a caption within the graphic (captions are separate text elements).
Any labels (text) appearing in the graphic should be in either Arial or Times New Roman font. And should be small, non-bold, and in lower case.
Maintain a copy of your original graphics (figures/illustrations) on your computer, in case we need to ask you to adjust or improve the resolution of a figure.

Lists: There are two list styles, bulleted and numbered. Bulleted lists are simple, and each listed item is separated from the next by a semi-colon. Numbered lists can be more complex (for example, outlining the steps in a process), with each item terminated by a period. A guideline for deciding whether to use a bulleted or a numbered list is:

If the items in the list are brief or not complete sentences, use a bulleted list;
If the list describes a process, or if list items contain more than one sentence, use a numbered list.

Use style CHI List Bullets A for a bulleted list. Use style CHI List Numbers A for a numbered list.

Variables: Use style CHI Variables A. Variables should be introduced by "Where:" Variables should be defined, where used, with full explanation and units of measurement. Please list these, one below the other, rather than incorporating them in the flow of the text.

SI Units: If using American units, include the metric equivalent in parentheses. Please see conversion table below.

Units of Measurement: These should be abbreviated. Please see conversion table below.

Numerals: Numbers over 21 should always be in numeral (digit) form. Numbers under 21, when used colloquially, should be written out in full e.g. "we ran thirteen tests"; "ten gauges were distributed." Numbers under 21, when used precisely or scientifically should be in digit form. A rule of thumb is that if the reader should be able to quickly find the number in the text, then it should be in digit form.

References: Use style CHI References A. See below.

Footnotes: Footnotes will not be accepted. Please incorporate such material in the text.

Footers: Do not edit or insert your own footers. We will insert footer material later.

Headers: Do not edit or insert your own headers. We will insert headers later.

Acronyms: Acronyms should be fully defined in the text on the occasion of their first use. The plural form should add a lower case 's' to the acronym (no apostrophe)

Reference Guide

The following gives examples of the main formats of references used in CHI’s Journal of Water Management Modeling.

We follow the in-text citation and reference list method, known as Author-Date References, detailed in the sixteenth edition of the Chicago Manual of Style (University of Chicago Press 2010, chap. 15). It is important to get the format of references (and citations) correct so Google Scholar can parse the reference and ultimately give citation counts.

Spacing, capitalization, italicisation, punctuation and commas are the main things to look out for. In the first example, the title of the paper is italicised, capitalised and appears in quotation marks. That is the format for just about anything (papers, conference proceedings, chapters …) except a book. Notice that the name of the first author is inverted but subsequent authors are presented initials first. There is a comma before the “and”, and a period (full stop) and space separate the authors from the date of publication. The journal title is italicised; take note of the punctuation after the journal volume number, and notice that an en dash is used in the page range.

Aronica, G., G. Freni, and E. Oliveri. 2005. “Uncertainty Analysis of the Influence of Rainfall Time Resolution in the Modeling of Urban Drainage Systems.” Hydrological Processes 19 (5): 1055–71.

If the annual volume number of the journal is used alone, rather than with the particular issue number, the page reference is slightly different.

Coles, S., L.R. Pericchi, and S. Sisson. 2003. “A Fully Probabilistic Approach to Extreme Rainfall Modeling.” Journal of Hydrology 273: 35–50.

In the two following examples the title is a two-parter and we prefer a colon as a separator rather than a dash. Notice also, in the book example, the place of publication and the publisher name is given. If you wish to include an ISBN it should be as a separate sentence after the publisher data. The book title is italicised and capitalised.

García-Ruiz, J.M., J. Arnaéz, S.M. White, A. Lorente, and S. Beguería. 2000. “Uncertainty Assessment in the Prediction of Extreme Rainfall Events: An Example from the Central Spanish Pyrenees.” Hydrological Processes 14 (5): 887–98.

Hosking, J.R.M., and J.R. Wallis. 1997. Regional Frequency Analysis: An Approach Based on L–Moments. Cambridge: Cambridge University Press. ISBN 978-0-521-01940-8.

In the following two examples, issues of a journal have been published together. We go with however the publisher indicates the combination.

The following is an example of a paper from a set of conference proceedings. The editors of the proceedings are not given, but if they were the names would be in regular typeface between the proceedings title and the page range. Note that the doi information is given as a separate sentence after the publisher data. Please include the full URL when referencing the doi, with no period at the end.
