Starting: Oranqe-Senqu Synoptic Surface Water Report

September 2021

AquaLinks has started with a project to assist the international Orange-Senqu River Commission (ORASECOM) with the compilation of a synoptic surface water report. The Surface Water Hydrology Committee intends to compile such a report every year going forward to inform the stakeholders and the general public of the surface water situation in the river basin parts in Botswana, Lesotho, Namibia, South Africa.

Ideas and inputs always welcome. Please send to me or my colleague on this project Mankoe Raliengoane!

Done: SADC Hydromet Forum 2021

June 2021

As team leader of the SADC World Bank project ‘Stocktaking of weather, water and climate services in Southern Africa’, Marieke presented in the session on status of Hydromet Services. She also was part of the World Bank coordinated organization committee of the forum, together with team members of Royal HaskoningDHV. Recordings are available via the website.

Done: Understanding Risk 2020 & WISA Conference

December 2020

Two conference presentations in one week:

Panel member in ‘Drawing a regional picture of hydromet and early warning services in Africa’ for the World Bank project ‘Stocktaking of climate, weather and water services in Southern Africa’ under RHDHV and

Co-author of presentation by Stuart Dunsmore for the WISA conference ‘Sustainable Drainage in Gauteng: Possibilities and Barriers for Implementation’.

This digital conferencing does keep us behind our computers, and gives less after talk, but DONE before the end of 2020.

Online: Final reports on Sustainable Drainage in Gauteng Province

April 2020

All deliverables on the project “Research on the Use of Sustainable Drainage in Gauteng” for the Gauteng Department of Agriculture and Rural Development are now available online via the Future Water Institute of the University of Cape Town.

This project was completed in March 2020, with the Urban Rivers Alliance (Fourth Element, Eco-Pulse, AquaLinks), NMA and Greenvision Consulting. AquaLinks provided project management, facilitation and organisation of workshops and meetings, contents contributions and editing.

Enjoy the reading and let it be for increased implementation of Sustainable Drainage in the whole of South Africa and beyond, but in particular in Gauteng.

Unveiled: Gauteng Sustainable Drainage Systems Implementation Manual

March 2020

Cheers to the finalization of the project ‘Research on the Use of Sustainable Drainage Systems for Gauteng’ for GDARD by the Urban River Alliance (Fourth Element, AquaLinks, Eco-Pulse), NMA, Greenvision Consulting and TAUW. It was an honour to be the project manager of the Consultants Team and facilitator of the Workshops and PSC meetings, as well as co-author of the deliverables.

Deliverables, including Implementation Manual will be soon published on GCRO and UCT website. AquaLinks will keep you updated.

Monitoring: High rainfall 7 to 8 February in Johannesburg 

February, 2020

This is what the TAHMO weather stations measured 7/8 February 2020 in Johannesburg:

  • Braamfontein had in total 130 mm measured! No wonder the M1 had to be closed (This was measured by a tipping bucket which we installed recently to check on the extreme rain measured there)
  • Alexandra, Jabulani, Hunters Hill, Midrand, measurements were all in the range 97-102 mm.
  • Be aware that on Sunday evening (not shown here) it rained again, with for example for Alexandra another 48 mm measurements!
  • Kibler Park firestation had such high rainfall measured (and earlier starting) that we do not trust it. According to not yet formally confirmed estimates of radar from SAWS there was about 120-140 mm there.
  • Orange Farm we measured hardly any rain, but radar did, so that one also needs a site visit to check and is not in the graph below. Although Rietfontein, also quite south, had far less than the others with 70 mm.
  • (The Florida Park station was stolen and is still waiting for funds for replacement.)

Making it known: TAHMO weather stations

October 2019

Life can be circular; From 1995-2001 I worked for Prof Hubert Savenije and completed my PhD under him in 2002. Fast forward 2019 and the 20th Waternet symposium is around the corner of the AquaLinks offices. Prof Dominic Mazvimavi is quoting Prof Hubert Savenije on the seed we all planted then. Waternet is now a tree under which shade a lot of IWRM researchers have grown.

AquaLinks is represented at the Waternet-symposium by Marieke de Groen and Fungisai Chiduku, together representing the Trans-African Hydro-Meteorological Observatory.

The plea is the same as in 1995: measure more and use the data!
