Prior to embarking on a course of study leading to the
Master of Environmental Studies degree I was employed by
Esso Australia Ltd. (Esso) as an Environmental Engineer
assigned to the Rundle project. One of the tasks that I
undertook in this role was the establishment of the Rundle
waste dump leachate program. I was involved in the project
definition, construction and installation of the field
research station, and with the ongoing modelling by the
University of Queensland. As a result of my work with them
Esso very kindly offered to make available, for the
purposes of this thesis, information collected by the waste
dump leachate program. Planning for this thesis commenced
in July 1986. One objective was to fulfill the need of the
Rundle waste dump leachate program for an investigation
into the influence of vegetation on water movement and
leachate generation. This had been identified as an area in
need of work for some time prior to the start of this
I have had an ongoing contact with the leachate program in
the role of consultant to the project. Esso have also
supported four site visits to Rundle to collect data for
this thesis.
A number of field studies are described in Chapter 4 of
this thesis. Some studies were carried out by me especially
for this thesis, other studies were carried out for the
overall leachate program by myself or other workers.
The soil moisture determinations described in Section 4.1
were carried out by a local contractor. The measurements
taken in the lysimeters were for the overall program. The
other soil moisture determinations taken in study plots 3

to 7 were made specifically for this thesis. I determined
the location of the access tubes, installed some of them
(with considerable help from Esso and the local contractor)
and defined the measuring program.
The lysimeter study (Section 4.2), was the key element in
the waste dump leachate program. I was extensively involved
with this program in my role as Environmental Engineer for
Esso and very fortunate that I was able to use the
information gained from the lysimeters in this thesis.
The runoff determinations (Section 4.3) were originally
initiated by me as part of the leachate program with a view
to incorporating the results into an assessment of water
movement in the vegetated layers. Thus the information
obtained from this study was not used until I commenced
this thesis.
The meteorological data (Section 4.4) comprises a central
element of the Rundle waste dump leachate program. One of
my responsibilities, both as employee and as consultant to
Esso has been the calibration and analysis of the Rundle
meteorological data.
Most of the information regarding material characteristics
(Section 4.5) was obtained from earlier rehabilitation
studies. The detailed chemical analysis was carried out for
the leachate program.
I obtained Leaf Area Index information (Section 4.6) and
carried out the vegetation survey (Section 4.7) to obtain
data for the thesis. The four site visits which Esso very
generously supported were primarily for collection of the
Leaf Area Index information and to carry out a vegetation
