Physical
modelling in a flume tank (Stellenbosch University & Utrecht
University)
Physical modelling of delta systems is an efficient means of
simulating the response of a delta system and to understand
its response to ambient conditions in terms of facies- and sequence
analysis. The objective is to define tools, that can be used
in field studies for well-logs, outcrops and seismic sections
alike. |
| |
Field
analysis of the Karoo Sequence (Stellenbosch University)
The Karoo Sequence is particularly well exposed from river to
basin and hence yields prospects to understand the system from
source-to-sink. The objective is to relate the system in terms
of facies- and sequence analysis and to test the tools that
were found in the physical models. |
| |
|
Numerical modelling (Stellenbosch University & Bochum
University)
A numerical model is an efficient means to test the sensitivity
of a delta system to the input signal. Numerical models are
to be run for the full range of values for tectonics, eustasy,
and supply. The objective is to find prototypes and critical
values. |
| |
 |
|
| The
response of shelf-deltas to cyclic variation in eustasy and
sediment supply. |
We
submit shelf-deltas in flume-tank experiment to cyclic variation
of sealevel (E) and sediment supply (S) for a number of prototypes/endmembers
under constant tectonic subsidence (Y). The scenarios include:
S in-phase with E, S out-of-phase with E, constant S, highly
frequent S. The next experiment will probably include pulsed
sediment input. The objective is to quantitatively define the
response of architecture to variations in controlling parameters
and to find tools to solve the inverse problem from the field.
We will be using field examples from Crete, Spitsbergen and
the Karoo to evaluate and test our hypotheses. |

| Opportunities
for Postgraduate Students |
| For
each project, the level (Hons, MSc, PhD), type (desk, lab, field),
title and outline are indicated. The outline gives the general
idea of the project. Candidate students should apply for the
given level of study, write a proposal on their project of choice,
send that to Dr. Mikes and make an appointment to discuss it.
Criteria for admission to a project are: qualifications / marks,
motivation and the project proposal. If accepted by both the
Department and Faculty, the department will supply a letter
of acceptance conditional upon availability of funding for the
project. Where required, funding for the project will be covered
by Dr Mikes, as supervisor. The procedure for obtaining a bursary
depends on the level. For Honours, bursaries should generally
be sought by the candidate externally; possible alternatives
can be discussed with Dr Mikes. For MSc, bursaries should also
be sought by the candidate externally; additional funding will
be provided by Dr Mikes. For PhD, bursaries will be provided
by Dr Mikes. |

P10/1
– PhD (desk) – Theoretical study of deltaic systems
How does a (deltaic) depositional system behave? How does it
grow and respond to external drivers? One objective of this
project is to run the ‘intelligent’ system “?Brain”
for a large number of deltaic scenarios. The other is to create
the database for that system “?Base”. The next step
would be to analyse the organisation in the results. The ultimate
question is: Can we recognise the signature of driving processes
in the field by particular features? |
| |
P10/2
– PhD (lab) – Physical experiments of deltaic systems
How does a (deltaic) depositional system behave? How does it
grow and respond to external drivers? One objective of this
project is to run physical experiments in a flume tank “Eurotank”
or “?Tank” for a number of ‘prototype’
deltaic scenarios. The other is to compare the results with
those from the numerical scenarios from “?Brain”.
The ultimate question is: What are the deterministic and probabilistic
parts of events in a deltaic system? The primary concern in
this project shall be the scalability of the system. |
| |
P10/3
– PhD (desk) – Analysis of sequence stratigraphy
What is “sequence analysis”? Can it describe the
temporal evolution of a (deltaic) depositional environment?
One objective of this project is to analyse the assumptions
on which “sequence stratigraphy” is built. The other
is to test the sensitivity of those assumptions to the results
of “sequence stratigraphy”. The underlying question
of this project is: Is deltaic behaviour predictable? If so,
which part of it is deterministic, which is probabilistic? And
if we can predict the future of a (deltaic) system, can we ‘predict’
its past? |
| |
P10/4
– PhD (field) – Facies/Basin analysis of Tanqua-Karoo
depocentre
What did the depositional system of the Tanqua-Karoo depocentre
look like and how did it fill the basin? The first objective
of this project shall be to establish existing tectonic models
for this basin and to analyse their probability. The other shall
be to construct possible 4D facies models for this depocentre.
A scenario should be designed for all combinations of tectonic
scenarios and facies scenarios. The model should be constrained
as much as possible by chrono-stratigraphic dates. |
| |
P10/5
– PhD (field) – Past/Future behaviour of Bot Valley
How is the Bot Valley evolving? One objective of this project
is to establish how the Bot Valley formed and was filled. The
other is to predict how it will evolve in the future. The history
of the valley shall be reconstructed from subsurface data (cores
and seismics), whereas the future of the valley should be estimated
from surface data (topography and bathymetry). The past should
give an idea of the response of the system to geologic events.
The future should give an idea of the sensitivity of the system
to climate change. The timing of tectonic events should be reconstructed
from Apatite fission-track analysis of the surrounding mountains. |
| |
P10/6
– PhD (desk) – Upscaling
How to characterise a reservoir? The objective of this project
is to design a procedure to build a reservoir model. It shall
then be tested by running it and existing procedures on a producing
reservoir. The procedure should address the uncertainty of all
elements, i.e. geological model, poroperm samples, data types
(log, core, outcrop). The underlying question of this project
is: How to build a reservoir model that incorporates fluid-flow
behaviour of bedding? |
| |
M10/1
– MSc (desk) – Design of deltaic system simulator.
What is a (deltaic) depositional system? How should one build
a model to simulate it? What should one measure to compare one
scenario with another? One objective of this project is to design
an ‘intelligent’ system “?Brain” that
both creates a database and draws from it. The other is to design
the database for that system “?Base”. The rules
for such a system should be physically sound and mathematically
simple. The main objective is to establish all driving processes
and their weight on one hand and to describe the deterministic
and probabilistic parts of each event on the other. |
| |
M10/2
– MSc (lab) – Physical experiments of deltaic systems
(Hon – Literature review)
Analysis of physical experiments of deltaic systems in a flume
tank. Several scenarios have been run for a scaled deltaic system
on a passive continental margin under controlled and varying
external drivers. The evolution of the system is to be reconstructed
from digital elevation models during the model steps. The resulting
architecture is to be analysed using lacquer peels from the
end of the experiment. The aim is to analyse the signature of
each driver on the geometry and facies of the system. |
| |
M10/3
– MSc (desk) – Numerical simulation of deltaic systems
(Hon – Literature review)
Analysis of numerical simulations by the delta-simulator “?Brain”.
A large number of scenarios is to be run and the results are
to be analysed and compared to those from physical experiments
from the flume tank “?Tank”. Digital elevation models,
cross-sections and vertical sections are to be used to describe
and compare the different scenarios. The main concern of this
project shall be to determine which features of the delta to
describe. |
| |
M10/4
– MSc (desk) – Reservoir characterisation (Hon –
Literature review)
Analysis of a reservoir model. An upscaling procedure is to
be tested on a producing reservoir. In order to do so the existing
data from that reservoir need to be analysed and the reservoir
model needs to be (re-)built so as to suit the procedure. Logs,
cores, seismics and existing reservoir model need to be critically
evaluated and the statistical methods and assumptions in all
the upscaling methods need to be compared. The critical concern
of this project shall be analysis of the uncertainties of each
of the procedures. |
| |
M10/2
– MSc (field) – Tectostratigraphic evolution of
Bot Valley
How did the Bot Bot Valley form? One objective of this project
is to establish how the Bot Valley formed. The other is how
it was filled. The tectonic formation of the valley shall be
reconstructed from apatite fission-track from the surrounding
mountains. The basin fill shall be analysed from subsurface
data (cores and seismics). The aim of this project is to gain
insight in the behaviour of the system on the geologic time
scale. |
| |
M10/3
– MSc (field) – Geomorphology of Bot Valley
How will the Bot Valley evolve? One objective of this project
is to establish the geomorphology of the present Bot Valley.
The other is to predict how it will evolve in the future. The
present geomorphology shall be reconstructed from digital elevation
models and surface samples. The future of the valley shall be
estimated by varying the base-level according to existing climatic
scenarios. The aim of this project is to learn the sensitivity
of the system to climate change. |
| |
M10/4
– MSc (lab) – Physical experiments of flocculation
(Hon – Literature review)
How do flocs form? One objective of this project is to create
flocs in a controlled laboratory environment for a range of
typical ambient conditions. The other is to analyse the data
and find an organisation in them. Part of this project should
be a critical evaluation of existing theory around flocculation
and the methods used to sample and analysis the data. The
aim of this project is to gain insight into floc growth and
decay as function of drivers. |
| |
M10/5
– MSc (desk) – Numerical simulation of flocculation
(Hon – Literature review)
How do flocs form? One objective of this project is to simulate
the process of flocculation in a numerical simulator for a large
range of ambient conditions. The other is to analyse the data
and to compare them to data from laboratory flocculation experiments.
The algorithms for flocculation shall be split into two; a deterministic
and a probabilistic part. This project shall serve to explore
the sensitivity of flocculation to the underlying physical/mathematical
models. |
| |
H10/1
– Hon (desk) – Lacquer peel analysis from physical
delta experiments
Analysis of physical experiments of deltaic systems in a flume
tank. Lacquer-peels from scaled physical experiments are to
be analysed in order to describe the 2D geometric behaviour
of the system. The underlying idea of this project is to use
objective criteria to describe the evolution of a system, i.e.
shoreline migration, stratal expression, thickness. Given the
fact that the drivers are known and controlled during the experiments,
the output can be tested to the input. The aim of this project
is therefore to establish whether there is a consistent relation
between input and output on one hand and whether 2D sections
are capable of describing a 3D system. |
| |
H10/2
– Hon (desk) – Digital elevation models analysis
from physical delta experiments
Analysis of physical experiments of deltaic systems in a flume
tank. Digital elevation models from scaled physical experiments
are to be analysed in order to describe the 3D geometric behaviour
of the system. The underlying problem of this project is the
inherent 3D nature of the system. Given the fact that the system
is known in 3D we can test its behaviour to existing theories.
The aim of this project is therefore to establish the deterministic
and probabilistic parts of a deltaic system in 3D. |
| |
H10/3
– Hon (desk) – Flocculation data analysis
Analysis of floc data. Floc data from physical experiments,
field surveys and numerical simulation is to be collected and
compared. The objective of this project is to establish systematic
behaviour of floc size as a function of ambient conditions.
The primary concern in this project is to ascertain that data
are comparible, which can be only guaranteed if all known drivers
are controlled and/or measured. This shall be the main obstacle
in this work. |
| |
H10/4
– Hon (desk) – Floc function analysis
Analysis of floc function. All existing floc functions are to
be collected and tested to existing data. The objective of this
project is to establish the value of each of the functions in
the following terms: precision, generality, simplicity. The
primary concern in this project shall be how to compare data
from different data sets. But the aim shall in any case be a
critical evaluation of the applicability of each of the functions. |
