This journal publishes refereed, original work in all branches of water science, technology, engineering and policy.  This includes: water resource development; the hydrological cycle; surface hydrology; geohydrology, hydropedology and hydrometeorology; limnology; freshwater and estuarine ecology; salinisation; treatment and management of municipal and industrial water and wastewater; treatment and disposal of sewage sludge; environmental pollution control; environmental and drinking water quality; drinking water treatment; water services, including domestic water supply and sanitation services; agricultural water; aquaculture in terms of its impact on the water resource; water policy and governance; water economics; water as a social good.  Water SA is intended to serve both international and Southern African readers and authors.  Contributions which are not of broad international interest must make a specific contribution to Southern Africa (defined for this purpose to include the countries of South Africa, Swaziland, Lesotho, Namibia, Botswana, Zimbabwe and Mozambique).  Submissions of predominantly local interest outside of Southern Africa will not be considered.

 

Contributions may take the form of a paper, a critical review, a short communication, a rapid communication, a technical note or comments on papers already published.  A paper is a comprehensive contribution to the subject, including introduction, experimental information and discussion of results.  (Technical accounts involving application of well-known techniques, and situation assessment/observation/sampling papers reporting results of work not carried out as a research activity, cannot be considered.)  A review is an authoritative, critical account of recent and current research in a specific field to which the author has made notable contributions.  A short communication is a concise account of new and significant findings to inform readers of preliminary or limited research results.  A rapid communication is an original contribution which merits prompt publication to publicise the findings of very recent research with immediate significance.  A technical note describes an original process or technique without necessarily including extensive data, theory or critical evaluation.  Comments on papers already published are sent to the authors of the paper for reply and both the comments and the authors’ reply will be published in the upcoming issue of Water SA. Preference is given to concise contributions.
