The water-diviner is capable of finding water under stones.
Everybody looks at him in amazement, completely confused
And he, armed with a simple wooden mechanism, scours the
territory until he point out- with complete certainty - the place
to dig the well. The people around him look at each other in
disbelief, but after he has solved the task, everyone locks
at each other with admiring.
The water-diviner is not a magician, he doesn’t have
Supernatural talents. The water-diviner has a technique.
He respect certain strategies when he walks around a piece
of land. He follows clues and he isn’t the one who
digs the well, but the one who point out the place.....
Sege aa catchment area lies in the southwest of Sweden.
Sege aa catchment area covers a total of 333 km2.
Risabergabecken further west, cover about 30 km2.
Sege aa and its tributaries has over the past 150 years
been subjected to increased emission of nitrogen and
phosphorus from both communities and agriculture.
Meanwhile, a radical change of the landscape has led too
a lost of self-purifying capability. Much of the water has
been led trough water pipes and has been straightened,
and the wetlands has been covered up. The
consequences has been that natural conditions for the
digestion of nutrients has decreased. Since the early
1900s, the area of wetland in the catchments area has
decreased by about 90% and distance open water has
decreased by about 50%.
Nutrients causes problems not only in the rivers
and lakes, but also in the sea. The pollution of the sea,
results in a sharp growth of algae’s. Dead algae fall down
to the bottom and decomposition leads to oxygen deficiency.
As a result, it could lead to fish death in big scale.
Phosphorus transport to the Øresund is about 10 tons pr.
year (average for period 1990-2006).

The streams catchment area, and sub-catchment area
During the process of evaluating and searching for pound and wetland loca-
tions in Seges catchment area has the need for a detailed breakdown of sub-
catchment areas become
clear, this by a systematic review of maps.
The work is exemplified below with bigger and smaller catchment areas, di-
vided into smaller areas in the most detailed level.
With the protection zone means a zone between water and arable land with grass and herbs,
and preferably also shrubs and trees. The with of the zone should be at least 5 meter and no
fertilizer or pesticide may be used in this area. The with of the protection zone varies between 5
and 10 meters
(today usually 6 m, according to EU directive).
- The transportation of soil particles and nutrients ( mainly phosphorus) from arable land to
- Decreased erosion in the water-ditches.
- The potential for direct deposit of fertilizer and pesticides in water decreases.
- Trees and shrubs shade the stream, which prevents overgrowth and reduce the need for
cleaning, by lowering the water temperature.
- Important corridors for the animals in the agricultural landscape are being created.
- Availability for people will increase.
Examples of protections zones between the arable land and the stream/water.

Pounds and wetlands
Pounds and wetlands have an important function when it comes to natural purification processes.
The processes that make the water cleaner is sedimentation (nutrient-rich particles sink to the bottom),
denitrification (water soluble nitrogen is converted by bacteria into the air nitrogen, which is harmless to
the environment) and through absorption of nutrients (plants take up nutrients in the pond).
Ponds and wetlands are effective nutrient traps in the area. The degree of purification depends among
others on the ponds design and age, and water retention in the pond.
Concept of pond and wetland.
The term pond in this context is a permanent body of water that is created to purify incoming water,
and is beneficial to plants, animals and humans.
The typical pond is made of a flat slope and has often an irregular shape, which is shaped by
the landscape. The depth can vary between one (1,0) and three (3,0) meter. And the size is usually
from 0,3 ha. till 5 ha. In periods of little rain the water level may be just beneath ground level. Aqua
vegetation plays a prominent role in our wetlands. Wetlands is typical in the ponds edge zone, which
means that the pond and habitats in our wetlands often are connected to one another.
The environmental benefits on ponds and wetlands.
- The water is cleaned when it comes to soil particles, nutrients, metals, pesticides and
other harmful substances.
- Habitat for wetlands-related plants and animals increases.
- Recreation potential for people in the agricultural landscape increases.
- Flood variations in the water can be reduced locally.
- Environmental damage at the temporary discharges of oil, urine or other harmful
substances can be limited.
- Biotopes in the local area will increase.
Smaller streams in the area
Sub- catchment area
To determine the size and boundaries of a catchment area, a map with elevation where
the state of water is clear. in order to get better glance, you may want to first draw the
arrows perpendicular to the height of the curves from higher to lower levels. These arrows
indicate direction of movement of rainfall water.
Water components can then gradually link together into coherent strings. In this way, the
catchment areas approximate boundary and size are identified.
Catchment area size:
To get a high nutrient load in the ponds and wetlands, there should be large catchment
areas (at least 100 times larger than the pond/ wetland).
Catchment area of 100 hectares or more is often needed. If the ponds can adjusted
accordingly to the catchment area, of course, we can work with small catchment areas
and still get a good effect.
Ponds and wetlands can be build in most soils, although soils with high clay content are
best because they provide a completely sealed pond.
Sandy soil with permeability involves a risk of leaking that can cause dehydration during
dry periods. The major technical limitation for construction of ponds and wetlands is the
relationship between the soil surface level within the proposed pond area and the level of
the running water. This ratio determines the soil volume it is needed to be excavated out
and thereby how expensive the project becomes. The higher the water level is proportional
to the surface of the soil, the better the conditions for creating a cost-effective pond/wetland.

Interesting for future development.
The agriculture land in the western Skåne, particularly near the
larger cities such as Malmo, is not seldom the subject of various
explorations plans. This may be the new road route. Wire rolls
and the development of new residential areas or industrial areas.
This has until now been a direct restriction in terms of the
development of ponds and wetlands in the area. But recent years
more people have become aware, and can see the quality of these
natural water areas/resources. As an important resource when it
comes to developing Malmö city in a sustainable ecological way.
To the best, for the people and the environment in Malmo.
Understanding the city
In the past, most attempts to understand the city scientifically have not seen the city’s
most obvious network - its street network – as being of scientific relevance or interest.
But it is the street network that links the aggregations of buildings into a single system,
it is what you see when you look down on a city, and it is what you navigate when you
walk or drive in a city. In all these senses, the street network seems to be the common
ground between the real space of the city and our experience of it. They say something
about how cities are structured spatially, how they work, and how they grow and change.
Networks of space have, in recent years, brought to light a fundamental link between the
structure and functioning of cities: that the configuration of the network is the primary
shaper of the pattern of movement. In shaping movement, it also
shapes the patterns of human co-presence - and of course co-absence – that seems to
be the key to our sense that good cities are human and social things as well as physical
things. This is a far reaching proposition, and, if true, as increasing evidence suggests it
is, it has far reaching implication for how we think about cities and design them. The
large scale architecture of city space, which has been neglected for decades, matters
much more than we thought to the life of the city and how it comes into existence.
In principle, this idea is not really new. Most designers believe that we can manipulate
space to create the emergent human patterns that are the source of our sense that cities
are civilised, safe and pleasurable.
People make trips because the shops are there. But it is maybe not fundamental. Maybe
the space network itself, shapes movement, then the shops are where they are because
they are following the patterns of movement already created by the network. So we can
not start with attraction if we want to understand this city. We should start with the network
which creates the pattern of attraction. So the network view of the city is also a paradigm
It puts everything in the city in a different order. Once we understand the relation between
the network configuration and movement, we can begin to creating a networks of centres
and sub-centres. This is the nature of the organic city which evolves over tens or hun-
dreds of yearsto form the seamless web of busy and quiet places, with everything seem-
ing to be in the right place, the organic city. How local places arise in cities depends as
much on how it is embedded in its larger scale context as in its intrinsic properties. In fact,
this is mabyetrue of space in general, and that the local-global relation has featured too
little in our attempts to reproduce the excellencies of cities through design.

Buildings and the city of Malmø exist for us in two ways: as the physical
forms that we build and see, and as the spaces that we use and move
So what is space:
The first is that we have to learn to think of space not as the background to
human activity, as we think of it as the background to objects, but as an aspect
of everything human beings do, in the sense that moving through space,
interacting with other people in space, or even just seeing ambient space from
a point in it have a natural and necessary spatial geometry: movement is

big barriers when it comes to social interaction between people in Malmø. in space we see a variably shaped visual field, and it is by accumulating
these as we move through the complex patterns of space we find in buildings
and cities that we somehow build an enduring picture of the pattern of space as a
whole. This describes some aspect of how we use or experience space,
and for this reason how buildings and cities are organised in terms of these
geometric ideas is a vital aspect of how we create them, use them and understand
them. For example, space in cities is for the most part linear – streets, boulevards,
avenues, alleys and so on are all linear concepts - with occasional convex elements
we call squares or public open spaces. So the language of city space is written in
this geometric language reflecting human behaviour and experience.
By filling these spaces, we see that the spaces are growing as the distance to
the city-senter increase. This indicate different human activities in diffrent
spaces. That means that different kind of people are attracted to their “ favor-
ite space”, or because of financial reasons. This means spaces of segregation

Micro - biology
Macro - city
Like the micro organism in water form a
pattern of lines, the city forms new lines by
looking for alternative streets/routes in the
purpose of braking up different spaces/ar-
eas. In this way new patterns can be build,
and the social interaction can develop.
Space shapes movement
The problem in Malmø is that all the main streets ( global streets ) is
occupied with car traffic. This becomes both a physical and mental barrier
This streets take you directly from the city
center and out in the rural area. The main streets
( because of the heavily traffic) makes barriers to the different
city spaces. This leads to segregation and different social zones in
the city. By locking for alternative spaces we can brake down these
barriers between these physical and social spaces.
Once we have this line network, we can calculate, say, the integration
value of each line in relation to all others, and color up as usual.
The global structures ( long lines) are given the colors red, yellow
and orange. The local structures are given the colors pink, blue and purple.
When ever tree colors mets in the network ( one global structure and two
local structures) we mark a connection point ( green circle) . A new interesting
space will then occur. And the the lines between the green circles vill guide us
