Assume. G_s = 2.7. Show transcribed image text. Expert Answer.Tree planting is more effective in lowering groundwater if salinity of water is low and where local flow systems, including perched water tables, predominate. This is because trees are able to take up less water with salinity above EC 5–10 dS m −1 and tree growth is impaired at such salinity levels.

The water table is high water mark. I suppose it's possible that there is a layer of drainable soil down below somewhere, but that's not realistic. The water table is the level where the soils are saturated below. You'd have to pump the water under pressure to this layer if it exists.
