National Groundwater Information System (NGIS) is a portfolio of projects designed
to meet increasing demands for groundwater information in a rapidly changing water
business environment. The system will be distributed among regional offices and
caters for the integration of spatial and non-spatial data and information. It also
accommodates increased visualization and analytical functionality.
The portfolio of the NGIS project includes several applications, namely
The National Groundwater Archive (NGA)
The NGA is a web enabled database system that allows capturing, viewing,
modifying and extraction of groundwater related data by registered users.
Currently the main focus of NGA is on point data known as Geosites (boreholes,
dug wells, seepage ponds, springs, etc). Line and polygon data will be made
available in future.
To register go to:

Enquiries: ngaur@dwa.gov.za
Currently there are about 254 200 Geosites on the NGA.
CHART
CHART is an integrated, hydrogeological
analysis and reporting solution that aims to assist hydrogeologists and hydrogeochemists
in decision-making during analysis and assessment of hydrogeological and hydrogeochemical
data.
CHART supports the analysis and assessment of the complete hydrogeological cycle and
hydrochemical trends in an integrated fashion with collaboration between groundwater,
surface water, and rainwater data in a single snapshot or dashboard.
CHART also fulfills an integral management role that aims to assist geohydrologists
with implementation and management of monitoring programmes and networks.

GEOHYDROLOGICAL
REPORTS SYSTEM
Geohydrological Reports System is a database that contains groundwater related technical
reports. Approximately 2600 technical reports are available in the library at National
Office. These reports reflect the hydrogeological investigations done by DWA officials
or consultants. A web based system allows one to inquire about the availability
of specific documents and are made available in PFD format.
To search the database go to: http://www.dwa.gov.za/ghreport

GENERAL
Other groundwater related documents or 1:500 000 Hydrogeological maps and brochures
are also available on request. (See ordering details) |
