Designing with catastrophic landocape events
How can a martial arts' philosophy be applied to
the way we design for locations susceptible to
My project explores opportunities in landscape
interventions that consider how we might design for
and live with the catastrophic landscape event of
My design approach is based on redirection and the
transfer of energy; through softness and flexibility,
rather than rigidity. In adapting the concept of
'acceptance' from my martial arts practice of Wing
Chun kung fu and applying it to my practice of
landscape architecture, landslides can be recognised
as a natural process of land morphology; one of
opportunity rather than destruction. Therefore a
condition of inclusion rather than exclusion should
be considered when designing with landslides.
My design incorporates a strategy which addresses
the issue of urban slums in 8 Salvador, as I am
designing the landscape where these shantytowns
(tugurios) coexist with landslide events. Through
the engagement of bamboo plantations, a micro
economy is generated to support the community,
stabilising and buffering the landslides.
Fbsitioning the body with good structure in
advantageous angles, redirecting opposing
energies and dispersing focused forces, Wing Chun
practitioners are able to control, diffuse, react to
and even use a stronger opponent's attack against
them. Employing landscape architectural practices
such as cut/ fill, terracing, grading, soil retention and
planting, I am applying the Wing Chun techniques
both physically and as strategies. From this my
design interventions begin to suggest various
ways in which we might inhabit a landslide prone
landscape. This aids a new condition that will not
only allow for the survival from the catastrophe, but
also enable informal settlements to improve their
living conditions beyond a cycle of poverty.
In 201 0, natural disasters killed more than 236,000
people worldwide, affecting more than 256 million
people and cost US$81 billion in the first nine
months of 2010 in repairs.
In 2011 , the Olristchurch Earthquakes and Tohoku
Earthquake and Tsunami caused more than 15,800
deaths combined, with the overall cost being more
than US$300 billion.
As t he world begins to realise and consider the
seriousness of how we deal with calamity, it must
be said that we have lived through many disasters
throughout history. In our effort to protect ourselves
and to prevent disasters, many strategies and
methods had been devised in attempts to deter, if
not counter the destructive forces of nature.
But is this the best thing to do? Is it even possible?
Can we truly control the forces of nature?
Is rejection and prevention the only way we
can live with catastrophe?
Through my design research project, my intention
is to investigate the disaster of landslides and how
we might engage, design for and live with such
catastrophic landscape events.
By applying my martial arts philosophy to the way
I design, the concept of ·acceptance' from Wing
OlUn Kung Fu was used to suggest an alternative
interpretation of landslides that is often forgotten-
one of opportunity rather than destruction and
In my design process, I utilised my personal
experience and knowledge of Wing Cllun techniques
to translate them into strategies which can be
implemented as landscape practices. These
translations also inform the way I generated designs
for the different iterations.
My design research was conducted through the
design of seven iterations of landslide interventions:
'Avoiding Problem', 'Fedirecting Energy', 'Controlling
Row', 'Protecting Ufel Diffusing Fbwer', 'Improving
Structure', 'Dispersing Force', and 'Reacting Event', to
explore the relationship between ditferent aspects of
the site and event.
My Site is in San Marcos, 8 Salvador, and consists
predominantly of lower to middle class families
living in urban slums. Rainy season during winter
increases the risk of landslides as the city sits at the
bottom of a valley.
To demonstrate how the design strategies might
work together, a scenario was created showing a
section of the site, which gets developed over ten
years. What is also interesting is the fact that my
research looks at two different time frames -long
term development and the immediate of disa&ers.
In my last iteration, Reacting: Event, a snapshot
of a landslide occurrence on my site taken from
the eighth year of development will depict both
timeframes within a single drawing, where my
strategies had all been implemented.
With this design research project, I am advocating
a different approach to how we think about natural
disasters. Through the understanding of Wing OlUn
techniques and landscape architectural practice, I
am suggesting a method of design for natural
disasters that focuses on acceptance through
redirection , rather than rejection through
Init1al Research Interest
At the beginning of the project, I was originally
really interested in the topic of catastrophe and how
design might be able to help with the adaptation to,
mitigation of, preparation for, protection from and
prevention of natural disasters.
Driven by the events of the Olristchurch Earthquake
and Tohoku Earthquake and Tsunami, I decided that
it would be a really interesting topic to venture into
as a 1\Aasters of Landscape Architecture research
I believed that landscape architecture can play
a major role in determining how well prepared a
community, town, city and country can become, to
protect us from natural disasters.
Being optimistic and enthusiastic, I decided to
challenge myself with the task of designing for a
foreign place where I cannot access physically,
where information was also limited. I also wanted to
design for multiple disasters and eventually this led
me to discover a country which lies on the pacific
ring of fire; 8 Salvador.
The diagram on the opposite page depicts a number
of major catastrophic events and their relationship
to other events. What I realised was that disasters
do not happen in isolation, because there is a cause
and effect, there is often a secondary and tertiary

8 Salvador is a country found within the Pacific
Ring of Rre and has suffered from years of civil
war as well as natural disasters, giving its capital
city the nickname "San Salvador La Oudad OJe Se

San Salvador has had a very high crime rate due
to gangs, such as the M& 13 and Galle 18, giving
it some of the highest murder rates in the world.
Corruption is also a big issue in San Salvador and
the divide between the extremely poor and the

gang violence and corruption situation has gotten
better since 2010, there is still a large divide
between the rich and poor, in living conditions,
monetary wealth, health and safety.

Slums, known locally as tugurios are often found
in hazardous landscapes because the safer areas
tend to be bought and protected by the wealthy.
Therefore their decision to build and live in locations
susceptible to landslides is not out of choice but
Because their dwellings are often made of scrap
material found by the residents, they do not have
much protection if a landslide happens. Aid from the
outside often does not address the issue either, as
they tend to be short term solutions rather than a
long term strategy.
Sl.BECT: LANDSLI DES
Wh at is a Landslide?
A landslide is defined by the Working Committee on
World Landslide Inventory as the · movement of a
mass of rock, debris or earth down a slope" where
movement is not only slide but aloo fall, topple,
spread, and flow in terms of kinematics.
It is a process of sediment movement which occurs
naturally, most of the time caused by torrential
rainfall and as such, have a higher rate of occurring
during the rainy seaoons in different rountries.
Generally landslides like most natural disasters, have
a negative connotation due to the negative effects
it brings to our society. This has caused many
governments across the globe to devise methods of
mitigation and prevention for landslides, to protect
their residents, economy and country.
The landslide type I focused my research on is
known as slope failure, where generally it is a
phenomenon where a slope (or part of the slope)
collapses abruptly, due to weak soil structure
caused by excess moisture in the ground, under
the influence of heavy rain or earthquakes. It is a
dangerous type of landslide due to its nature to
collapse suddenly, usually without warning, thus
it becomes a hazard in residential areas where a
higher rate of fatalities can occur.

subject because it's a phenomenon which changes

Whilst I understand the reason why people think
of landslides as a hazard, a problem, what I
am arguing is that it can actually be seen and
interpreted as a positive, but to do that one
must be able to accept and recognize that it is a
naturally occurring phenomenon of earth, or land
morphology. It is a process of roil depostion, and
in most cases, stabilization as well. Landslides carry
various benefits besides the initial and immediate
destruction. It allows for new soil to be deposited
which can benefit new plant growth in areas where
nutrients are lacking; it brings debris which can
become habitat for certain animals, which in some
cases are essential to their survival. These positive
effects are opportunities for survival, but can only
be recognized in the long run. As ruch, landslides
also become beneficial to the development of
disadvantaged communities, where the risks
become overshadowed by the opportunity the slope
presents, in the form of space for living.

the sole purpose of landslide defence, but also to

In Wing Chun we don't block attacks, as we believe
that blocking means you are still getting hit. Instead,
we use the concept of redirection, where we allow
the attack to commence, and receive it whilst
redirecting the energy away from our body. This
is done by positioning your body in certain angles
where you are able to intercept the path of the
attack while maintain control of where it will go.
Masters of this are able to allow attacks to come
very close to hitting them without actually getting
In terms of my research project, this notion of
redirection is important because it differs from the
conventional method of blocking landslides with
walls, or fi nding solutions to prevent landslides.
It is through redirection of the forces that we can

ourselves in order to evade the dangers yet still

Landscape Architecture vs Wing Chun
Anticipation & Reaction
As landscape architects, we tend to design in
anticipation for what may happen in the future,
because we are designing for future conditions. Our
design projects seldom it ever become ·complete'
(in the sense of how we envisaged it) when
construction is first completed. Aants take time to
grow and other conditions might need to be met , all
in a matter of time.
As Wing Olun practitioners, we are taught not
to anticipate, but to react instead. Because by
anticipating, you are predetermining a response to
something that may or may not oocur in the way
you expect it to. This causes you to react slower to
an attack that is unexpected, potentially leaving you
Landscape architecture projects deal with a long
time frame in which the strategy comes into fruition
not immediately but over time; it may take years,
decades and even centuries. The area of effect of
our design moves in the landscape can be really
large, but sometime it can only be seen as a whole
from a distance and is not so obvious when up
Wing OJUn works at very close range, any dispute is
dealt with immediately and is usually over within a
matter of seconds.
From this comparison of time and space, Wing Olun
and Lands::ape Architecture seems to be complete
opposites -working at vastly different timescales.
However the time it takes to build up the skills
required to perform Wing Chun efficiently and
effectively may take years of training, and practise;
all for several seconds, in a moment of life or death.
The better prepared you are the better chance of
In order to reach a state of resilience that is able to
react to unexpected events such as landslides (as
it is difficult to foresee the size, time and location) ,
we must be able to maintain a constant reading
of the landscape. This is unrealistic in a landscape
architectural sense because we cannot be there
indefinitely to redesign and prepare for future
events. Therefore conventional disaster interventions
are rigid and opt for engineering based solutions
which work within a limit, are unable to adapt to
the unexpected. While there is sometimes ongoing
management in terms of maintenance for these
defence structures, it is still about predetermining a
response and is therefore not flexible.
In order to respond to events such as landslides
which may occur in a time frame that is abrupt,
landscape interventions must become adaptive and
responsive. The only way to do this is to educate the
community that is being protected. The strategies
which are to be implemented over time needs to be
understood as well as the site itself. Through a fine
tuned reading of the site, appropriate measures can
be implemented to prepare for the unexpected.
The following precedents are similar to my design
research project, but different.
Siglufj orOu r
This is an avalanche deflection dam in Iceland.
This project gave me the initial idea for my landslide
deflection dams which I designed in my ·avoiding'
Blue Isles Plan
This project of reclaimed islands was a precedent
from the very beginning of my research (while I
was still researching disasters); because it had to
do with changing the landscape (or seas::ape) in
order to protect an important and vulnerable area.
The agenda for safety also catered for extra housing
possibilities as well as habitat creation for wildlife.
Sabo is a precedent because it had been tested
throughout history, in Japan, as sediment defence.
Although it seems to be the perfect precedent for
my research project, it is actually quite the opposite
of what I am aiming for in my design; in terms of
approach and philosophy.

the Icelandic town of Siglufjorbur by deflecting

The defence structure also doubles as a recreation
area, with paths running around the structure and

mountain, and has a viewing platform at the end of
In many ways this project was successful as it is
effective in deflecting the avalanches that endanger
the lives of the town's residents. What it is also
notable for is the fad that besides being a defensive
structure with a very dear purpose, it has been
designed so that it will not be an eye sore. In
emulating the ridge forms on the mountain, the
deflection dam's direction and flow also allows it to
become camouflaged and almost seem as if it was

the town's residents, as it basically allows them to
survive in this previously hazardous landscape.

Deflection Dam and town, winter
Avalanche Deflection Dam :n
This project is similar to mine in that it is also a form
of sediment defence.
Where it differs is that this project is still about
exclusion; to reject the avalanche by deflecting it
into the sea behind the town.
However it is still much more innovative than the
commonly used engineered solutions, where they
disregard the effect the structure will have on the
community. Oler time vegetation will grow over it
and it becomes part of the landscape.
This project is also about predetermining a
structure, because based on past avalanches, they
can predict where avalanches might occur when it
snows, whereas with landslides, once it happens,
the soil moves to the bottom of the slope and the
landslides cannot occur in the same way again.

Japanese Sabo Works ;;J ~
In Japanese the term Sabo literally means "defence
against earth", which translates to something along
the lines of "the control of and protection from
It deals with anything sediment related from debris
flow, slope failure, landslides, volcanic mud flow,
avalanche, to stream erosion control.

typical sabo intervention for debris flow consists
of building permeable check dams on the path of

be captured and held temporarily to protect the

Landslides as defined by the ..Spanese sabo
associations are the movement of a large area of
landmass, also known as J.landsJides; which is a
different type of landslide to what naturally occurs
on my site, and in my research. Typically this type of
landslide is difficult to stop once it has started due
to the size, but can be prevented through the use of
extensive drainage and retention interventions.
Sabo works for Slope failure type landslides
Sabo interventions dealing with slope failure type
landslides are mainly made up of 3 types: wall
type, which is the most intrusive to the landscape;
ground surface type, which can be just as intrusive
as the wall type unless care is taken to 'hide' it in
vegetation, or careful consideration to where and
how it is placed; and lastly the fencing type, which
causes the least damage to existing vegetation,
because it can be arranged around existing trees.

Retaining wall works
Concrete retaining walls are built on the lower
part of a slope where a collapse has happened
to suppress it directly as well as catching further
collapsed soil , protecting the houses down below.
Soldier piles and lagging works
Steel piles are driven into the slope to restrain the
collapse of the surface soil layer, and then lagging
is placed between the piles to prevent downward
movement of the eroded soil. This method can be
applied without destroying existing vegetation.
Grating crib works
Concrete frames are laid onto a slope in
which vegetation can grow to help retain soil,
preventing erosion. This method can be used in
conjunction with ground anchors to directly act as
a suppressing struct ure to prevent slope collapse.
Existing vegetation can be retained by adjusting
arrangement of the frames.

Reflection on Sabo strategy and my strategy
Sabo works are the solution to sediment disasters
in Japan and has also been the precedent for
many other countries' sediment defence. But
the difference between these Japanese sabo
interventions and my design interventions is the
Sabo works tend to be engineering focused and
often utilises a hard/ harsh style of preventative
response to landslides to 'fix the problem'.
I don't believe that it is the only way; instead,
my strategy is one which accepts the landslide as
a natural process, and through my interventions
redirects the flow of the landslide to actually
create opportunities out of a calamity rather than
attempting to prevent it.
Whilst sabo interventions might be effective and
appropriate in Japan, where space is limited,
this does not mean it will be a right fit for other
countries, cultures and environments.
In order to become more resilient to disasters, we
must not become too complacent in depending on
'technology', as demonstrated in the devastation
of the 2011 Tohoku Tsunami, where complacent
residents did not heed the warning systems to
evacuate when the tsunami hit the east coast of
Japan, as they thought that nothing can break
through their seawalls and breakwaters. It was a
painful reminder that whilst we might be able to
build large structures, carve out mountains and fill
in the sea, our interventions are of little hindrance
to the forces of nature, when a disaster beyond our
predictions hit , only t hose with enough preparation
and resilience will survive.

Throughout my design project, my intention was
to facilitate the coexistence of disadvantaged
communities and landslides. From the initial desire
to solve the problem by avoiding it , to embracing
and facing the challenge of designing with
catastrophe, I explored various design concepts to
eventually find an approach to design which I can
call my own.
Bringing my knowledge and my passion in martial
arts, I was able to utilise this knowledge to inform
my design interventions. By translating Wing 01un
techniques into strategies in dealing with landslides,
I designed landscape interventions that respond
to different stages of development on a location
susceptible to landslides.
Based on what I learned through the design and
investigation of different design iterations, I created
a scenario on which I can test how the different
iterations might operate together. The scenario is
represented in a timeline over a period of 10 years
and is further demonstrated in a sectional elevation
across the slope, where an event of a landslide
amongst other interventions implemented on the
site, is depicted.
