Call for Papers: SAJG Special Issue


South African Journal of Geology Special Issue: Southern African Hydrostratigraphy

Guest editors: Dr Matthys A. Dippenaar (Department of Geology, University of Pretoria) and Dr Shafick Adams (Water Research Commission)

Southern Africa, with its geological and natural diversity, is affected by highly variable distribution of fresh water and equally non-uniform rainfall patterns.  The fresh water scarcity is exacerbated by the cost of energy for desalinisation; the cost for construction and maintenance of water infrastructure such as dams, wastewater treatment works and pipelines; urbanisation and population growth; and the very real effects of climate change affecting the distribution and intensity of precipitation.

This special issue is devoted to Southern African Hydrostratigraphy.  Earth scientists continuously source new information regarding the mechanical and hydraulic behaviour of different lithostratigraphic units in South Africa.  Aquifers, aquitards and aquicludes play a fundamental part in the water cycle, and understanding how the same medium behaves in both saturated and unsaturated state also has significant implications on groundwater recharge, aquifer vulnerability, and the engineering properties of earth materials in urban development. 

Contributions to this issue is invited.  Manuscripts should (i) describe the lithostratigraphy, geology and hydrostratigraphy of a selected region; (ii) collate relevant bibliography with respect to the state of knowledge of the given hydrostratigraphical system; (iii) detail contributions to the understanding of the mechanical, hydraulic and/ or geochemical behaviour of the system, (iv) update existing conceptual understanding with new knowledge, and, if possible, (v) comment on anthropogenic impacts on the system and vice versa. 

Calls for this special issue should present novel data, and not merely reinterpretations of existing data.  Papers should contribute to a broader interest than only phreatic hydrogeology, and should incorporate, for instance, properties of confining horizons, vadose zone properties and/ or urban or other anthropogenic influences.  This would, therefore, be of great value not only to hydrogeologists, but also to those interested in weathering, pedogenesis, dewatering, corrosion engineering, strength implications of wet earth materials, and project life implications of altering subsurface hydrological systems.  For this reason, collaborative efforts are preferred to ensure that multiple authors working in the same hydrogeological setting can contribute to a single high quality reference.


  • Intentions to contribute should be communicated to the guest editor no later than 31 October 2018.
  • Submissions should comply with the requirements for the journal, available at
  • All submissions should be CC’ed to madip [at] up [dot] ac [dot] za (subject: SAJG) with a clear subject line stating “SAJG”
  • All submitted papers will be subjected to normal peer review if deemed relevant by the guest editors
  • All submitting authors avail themselves to reviewing at least one other paper for this special issue

To ensure that the special issue can be published by mid-2019, first submissions have to be received by the guest editors by 31 October 2018 latest.  This allows enough time for peer review, corrections, and acquiring enough papers for a strong special issue.
