Geohydrologists scientifically investigate and evaluate underground water resources, their quality and characteristics. They are involved in the exploration of groundwater by means of geophysical techniques.
Geohydrology is a relatively new science and is an important field for various reasons. Many reservoirs cannot hold as much ground water as before, due to sedimentation. In recent years, there is also a much higher degree of public awareness regarding healthy or contaminated water. Geohydrology helps improve quality of life and environmental safety.
Groundwater is a natural resource of ongoing importance. As surface water resources become fully utilised, the importance of groundwater will increase. More than 100 towns in South Africa are completely dependent on groundwater. Groundwater is also important for the mining industry, while irrigation from boreholes is also increasing rapidly.
Geohydrologists investigate the occurrence and exploitation possibilities of groundwater in different geological formations. They investigate the quality of groundwater and study groundwater systems by means of mathematical models and statistical analyses. They render expert advice to institutions and users of groundwater. The work of geohydrologists varies from office work to fieldwork.
Geohydrological technicians: assist geo-hydrologists by working with computers or files to store information; using geohydrological measuring, testing and collecting equipment and other technical equipment.
Suggested training for technicians:
Diploma: Diploma in Water Care - TUT
Schooling & School Subjects
National Senior Certificate meeting degree requirements for a degree course
Each institution has its own entry requirements.
Degree: BSc degree - most universities. Hydrology can be followed at UKZN, UV and UZ, and Groundwater Studies at UFS.
Post-graduate study is recommended, for example BSc (Honours) degree with appropriate subjects such as Geology, Physics and Mathematics.
Preference is given to candidates with qualifications that include courses in Geohydrology, a BSc (Honours) degree in Geohydrology and specialist training such as Applied Geophysics.
