Collaborative development and decision-support
AWARD focuses on the collaborative development and testing of protocols for responsiveness and action as part of an Integrated Water Resource Decision-Support (InWaRDS) system for compliance and early warning. Monitoring needs to be embedded in a responsive system that is linked to action and change. An example of this has been efforts to ensure continued flows in the lower Olifants during the drought of 2016.
An example of co-operative governance: securing environmental flows in the lower Olifants
In response to the crippling drought and non-compliance with environmental water requirements in the lower Olifants, and in support of good, adaptive governance we started work on securing a shift of water use from the Blyde to the De Hoop Dam (currently at 42% capacity) to augment flows in the lower Olifants. If the dam drops below 25% water cannot be abstracted for irrigation, placing 10 000 permanent and seasonal jobs at risk. In response to requests by DWS, and a letter from the Acting Managing Executive of the Kruger National Park and recommending the use of the RESILiM-O model to achieve this, DWS agreed.
A major success for RESILiM-O was the acceptance of these recommendations and the release of water from the De Hoop Dam on 23 September 2016. The dam releases resulted in the Environmental Water Requirement (EWR) being met at Kruger National Park’s Environmental Water Requirements site, Mamba Weir – a major success in a time of drought!
A suite of integrated water resource decision-support dashboards are being developed to guide water resource managers in making short- and long-term strategic adaptive operational decisions. Both the tools and training have been trialled in the Olifants River Catchment during 2017. A mobile app (Flow Tracker) and a desktop dashboard have been developed – a first for the region and country!
FlowTracker mobile app
The FlowTracker mobile app tracks river flow and dam levels in real time and gives rainfall forecasts. This allows the user to track flows against the Reserve (Environmental Water Requirements). The public version of the Flow Tracker mobile application was launched in March 2017. Available at https://play.google.com/store/apps/details?id=flowtracker.award.org.za.flowtracker&hl=en.

The dashboard boasts the capabilities of a rapid overview of EWR flow compliance (A), rapid dam level assessment (B), flow gauge time series compliance analysis for historical and near-real-time data (C), and a water quality assessment tool (D).
Real-time data loggers
AWARD has installed data loggers for flow and water quality at key sites in the Selati and lower Olifants River. This is because data needs to be verified in real time but, as has been noted nation-wide, the gauges often malfunction due to operation and maintenance challenges.
With support from USAID, and collaboration with the Department of Water and Sanitation and SANParks, data loggers have been installed at the following sites:
- Liverpool Weir (B7H009; Olifants mainstem, escarpment foothills)
- Oxford Weir (B7H007, Olifants mainstem)
- Balule Weir (B7H026; KNP before Mozambique border)
- Mamba Weir (B7H015, KNP below Olifants-Selati confluence) as well as a water quality gauge
AWARD also supports DWS and SanParks in monitoring river flows. For example, we visit Oxford Bridge (B7H007) along the Phalaborwa-Hoedspruit road to take water levels at weekly intervals to support DWS hydrology staff in Pretoria.
