The water table is the level of the ground water under the ground from the surface.
The water table means?
- The water table is the top surface of the saturated water area or level of the water from the surface level.
- You will notice that people always refer to as “how high is the water table”.
- The water table may be higher or lower in the ground, depending on how much rain fall in that area.
- Fog and heavy mist can also have an effect on the water table.
- The depth of the water table can vary from ground level in some areas in the western Cape to 80 meters or more.
- During the winter months the water table is at its highest in the Western Cape due to the fact that their rainy season is during the winter.
- Inland like Gauteng the water table is at its highest during the summer due to the rainy season.
The level of the water table.
- The level of the water table can fluctuate from area to area.
- This is due to the ground formation and the ground structure.
- Sand tends to have a higher water table than Clay or Silty soil.
How to measure the water table.
- The only way to measure the water table is to dig a hole in the ground or drill one.
- At some places during the rainy season you would just dig a 30 centimeter hole and you will notice the water seeps through the ground to a level.
- That is the water table for that specific area on that time.
- During the non-rainy season you will notice that the water table would be much deeper.
