The dashboard reports on the current status of groundwater resource in South Africa. The intensity of drought will be indicated by comparing the current groundwater level against the maximum and minimum groundwater levels ever measured at geosites. This data is then display as a percentage value that can be compared with other geosites. The measurement of groundwater levels that are displayed as percentage value provides information about groundwater level status at a regional, provincial and also provider a broader picture of groundwater status at national level. The dashboards utilise the time series data from Hydstra database and this will assist in the prediction for future trends.
The dashboard aims to answer the following questions:
All groundwater data collected by DWS is stored in a commercial hydro-informatics database called Hydstra. The data is collected in the field at monitoring stations which are maintained and operated by DWS regional offices staff. The information collected is critical for the effective and sustainable management of groundwater resources in South Africa.
Some Meta data is populated in the table format that is relevant for the groundwater monitoring stations. This information is extracted from relevant fields in Hydstra by NIWIS.
The data is extracted monthly basis.
