Is there a study relating water table to construction/RCC activity?

Background:

The soil in our locality is/was Black Cotton Soil - mostly from weathered humus over the years. Our locality was also mostly large (by Indian standards) plots mostly with load-bearing walls - so there plenty of houses had enormous trees/gardens/what-not.

Over the last decade or two - the old load-bearing houses with clay-tile roofs have been replaced by multi-storey concrete column/beam apartments.

The result is drier soil ( we hit 46C regularly in summer for upto 3 weeks this part of the world ) in those parts of the locality that have not been concreted/asphalted over by construction/roads during the dry part of the year. The converse is true during the wet part of the year - extreme waterlogging is observed. Larger trees survive - smaller plants do not... or barely so.

I suspect this may be due to a double-whammy - greater sewage, and greater run-off after rain due to the soil excavated to accommodate concrete, smaller number of trees/roots to absorb moisture & retard soil runoff.

What are the expected changes in the water-table of a locality *post* "evolution" to a concrete column/beam structure?
