0 the level below the surface of the ground at which you start to find water --
1 the layer below the earth's surface where water is found --
Blocks with water extraction more than recharge indicate receding water table zones.
According to the relative abundance of legume species, possibilities for comparisons between plots, and water table, representative species and individuals were chosen for nodulation studies.
In either case the toxic or radioactive waste is trapped in the solid, preventing it from leaching into the local water table.
It is produced in the dry season, in areas with a high water table or with irrigation, and in the rainy season.
Both environmental changes could result in water table changes fatal for survival of some plant species.
The water table had an average depth of 25 cm along the sampled radial segment and was visible in the depressions.
This is particularly suggested by the succession of evaporite couplets, which are attributed to pulsating episodes of water table change.
These gradual rises in the number of plant species reflect improved peat-forming conditions resulting from local rises of the water table.
