1998) might identify lines of acacia that are suitable for use in revegetating regions of rising saline
watertables such as the Salic Hydrosols in Western Australia.
The model predicted that the
watertable in the Subdivision would go down to 6.
This excess water moving below the root zone has thrown natural hydrological cycles out of balance, causing
watertables to rise beneath catchments, much like the filling of a bathtub.
Water meter readings and
watertable elevations were also recorded each month.
Watertable is partly the product of adjusting to his environment.
Ultimately, piezometric monitoring showed that this salinisation process depends on groundwater dynamics and is more severe when the
watertable is near the surface.
This suggests that salt was not leached from the profile by winter rains as the
watertable dropped.
Subsequent evapotranspiration then causes the
watertable to drop quickly and the roots again grow.
WAPDA at Mona Reclamation and Experimental Project has shown raising of crops with less number of irrigations in high
watertable areas.
Soils where the
watertable is close to the surface are at a greater risk of nitrate losses.
Work includes repairs and replacement of kerb and
watertable, profiling of roads and resealing (including line marking).
The cause is a seasonally perched (saline)
watertable that is not connected to deep (phreatic) groundwater.
