TSUNAMI MODELING AND SIMULATIONS
*Course week and
*Project week
Bandung, 12 - 23 January 2009
Organized by
Laboratorium Matematika Indonesia (LabMath-Indonesia) in collaboration with
- Institut Teknologi Bandung, and
- University of Twente, the Netherlands
*This activity is a part of KNAW Mobility Programme 07MP11 (Royal Netherlands
Academy of Arts and Sciences)*
AIM AND DESCRIPTION
Scientists have already a good qualitative view what happens when a land plate
suddenly slides over an ocean plate and thereby brings the water above the
moving bottom into motion and excites a tsunami. On its way to the coast, the
tsunami conserves energy and its amplitude increases when entering the
shallower coastal areas. We have seen dramatic effects on the coast when the
tsunami runs over land.
Scientists have made models to translate the qualitative ideas into models and
simulations to get quantitative results; many ‘tsunami codes’ exist.
Amazingly, when simulation results are compared with field-observations on the
coast, it turns out that often the simulations of wave heights are a factor two
or three wrong. We will address several aspects that may lead to errors in the
simulations because the modeling is too complicated and not yet
well-understood. We will discuss, and make projects, on the following aspects.
One topic will be the evolution of water waves, from basic properties such as
wavelength and amplitude dependence on depth, to more advanced aspects of
inverse modeling to estimate the initial tsunami waveform from measurements at
buoys. Another topic will be the wave excitation process: the basic principles
and the more difficult modeling of the tectonic plate motion, and the
translation of bottom motions into tsunami properties such as initial waveform.
One topic will deal with the complicated overland flow when the tsunami reaches
the coast; we investigate how details of vegetation and buildings influence the
run‐up (inundation) height.
Although this tsunami topic from geo-science is interesting and relevant in
itself, the RWS may be very valuable for participants with different
background, because the methods from applied mathematics and the modeling
experience are useful for many other areas in science and technology as well.
In this RWS we aim at a stimulating atmosphere where participants from several
disciplines will work together. Except the lecturers, we will also have young
students who will contribute to the exercise periods and to the projects. They
have been working for some time as junior researcher with an internship at
LabMath-Indonesia on (related) topics to support the research in the KNAW
Mobility Programme.

PROJECTS
Below we list the titles and a short description of the project topics.
Project 1 : TSUNAMI CODES
The aim is to design and implement a simple tsunami code in 1D above synthetic
bathymetry to illustrate the basic properties of amplitude and wavelength
changes with changes in depth, and to select well defined conditions (tsunami
generation scenario, physical domain and bathymetry) such that tsunami
excitation and wave development till close to the shore can be simulated. We
will be interested in the effects on the near-by coasts.
Project 2 : WAVE GENERATION BY BOTTOM EXCITATION If we lift part of the bottom
below a layer of fluid, the incompressibility of water will give rise to
disturbance of the initially still free water surface. The aim of this project
is to find out what the influence is of the bottom excitation on the generated
waves.
Project 3 : INVERSE TSUNAMI MODELING AND SIMULATIONS Given data consisting of
time signals of surface elevation as measured by buoys at one or more
positions, determine as much as possible information about the tsunami
excitation process: the bottom profile displacement and the dynamics of the
bottom, with the aim to characterize the tectonic plate motions (shape and
dynamics).
Project 4 : BOTTOM EXCITATION FROM SEISMIC DATA Another way to extract
information about the tsunami excitation process could be to find as good as
possible a characterization of the tectonic plate motions (shape, displacement
and dynamics) from seismic data. In several stages of complication, we want to
develop better insight in the generation process.
Project 5 : TSUNAMI WAVE AND INUNDATION HEIGHT ON LAND This project
investigates the tsunami when it has reached the land, centered around the
question what the inundation height will be, and most important, how this
height depends on the depth gradient of the ocean bottom, and on vegetation
(mangroves) and defense measures on the land.
PROGRAMME LAY-OUT
The first week is a Course week, with lectures and exercise classes. This
Course week can be attended by maximal 30 participants. At the end of this
week, the projects will be introduced and Project groups will be formed. At
most 20 participants can continue with these projects, when necessary selected
based on their performance during the Course week. This project work will be
executed during the whole second week with close guidance by the RWS lecturers
and junior LMI researchers. Participants will prepare written and oral
presentations of their work. Arrangements for further activities will be made
if applicable. After the first week of courses, a visit to BMKG (Badan
Meteorologi, Klimatologi dan Geofisika) Jakarta is scheduled, to see the
recently inaugurated InaTEWS (Indonesian Tsunami Early Warning System).
AWARD/CONTINUATION
For at most three of the best performing participants, a continued activity
will be designed. Such a continuation may consist of further study and own
research investigations in a specific topic. Working on the topic may include a
period of several months as guest of LabMath-Indonesia in Bandung.
During these periods, and as much as possible also during other periods using
email for correspondence, tutorial guidance will be provided by one of the
lecturers of the RWS. When achievements are good, sooner or later the results
will lead to an application for a research grant, to an international
publication, and/or to a visit or following a study programme at a university
abroad, whatever is possible and desired. The best performing participants will
be invited and guided to write a research proposal to be submitted to (inter-)
national funding agencies.
PARTICIPATION
Students and staff from state or private universities and staff of governmental
organizations can apply for participation. Especially young S1 students in
their final year and S2 students are strongly encouraged to participate. To
profit from the course, participants should be eager to learn new topics, both
the theoretical background as well as the specific applications. In general,
basic knowledge of water waves and/or seismology is required. Students with a
math, physics, geo-science or engineering background will be able to enjoy the
lectures and projects. Programming skills (Matlab, Maple), will be needed in
the execution of most of the projects. The applications will be thoroughly
examined, and at most 30 participants will be allowed to participate in the
first Course Week and 20 participants in the Project week.
DEADLINE FOR APPLICATION: 27 December 2008.
NOTIFICATION OF PARTICIPATION: 5 January 2009.
Participants who register earlier may receive sooner notification of
participation.
FEE AND SUPPORT
For participation a fee is requested of Rp. 1.000.000 for registration before
27 December 2008, and Rp. 1.500.000 thereafter. This fee includes the workshop
material, lunch and coffee/tea during breaks, and the workshop dinner. Support
is given to reduce the fee for young students to Rp. 100.000 and for university
staff members to Rp. 500.000.
