| Consider a layer
of soil 2.5 m thick, with 50% porosity.
A change of 2% v/v in moisture content of this layer would produce a
change in the gravitational acceleration at the surface of 1 G (10 nm s-2), which is at the limit of
resolution of present-day gravimeters. |

| Additional sites
for the measurement of gravity, soil moisture and groundwater level will be
installed across the Murrumbidgee at two distinct scales. Seven additional sites will be installed to
provide measurements approximately every 50 km in the east-west
transect. A further fifteen sites will
be installed in the Kyeamba Ck sub-catchment to provide data on an
approximate 3 km 3 km grid. (Total of 22 extra soil moisture
sites) |
