Stage-discharge equations for lakes without disharge measurementsSimon AnderssonIn 2015 all lakes, rivers, coastal water and groundwater should be of good ecological statusaccording to the water framework directive from the European Union. In the process ofimproving the quality of Swedish water bodies, knowledge of where problems occur isneeded in order to utilize the resources optimally. The ability of lakes to store water is animportant factor since it controls the flow of water through the country. A stage-dischargeequation is a mathematical relation between discharge from a lake and its water level. Bybetter understanding of stage-discharge equations for lakes, their storage capacity can bedescribed better in hydrological models.This master thesis aims to evaluate methods for determining stage-discharge equations forlakes where a variable amount of field measurements is available.

Theories of sustainable development are discussed, along with the importance of communication for sustainable development. The report is directed towards landscape architects, architects, town planners, other designers and other interested readers.MotivationI believe that there is a need for an increased discussion concerning sustainability. Sustainable development is an important issue for city planners.
Förändringar i vegetationens sammansättning efter en våtmarksrestaurering : Changes in the vegetation composition after a wetlandrestoration
The loss of such great wetlands, which has arose in Sweden the last decades, has created a situation that threats both the function and the biological diversity within the wetlands. Many ecological niches can be found in the wetlands and it is one of the habitats where most different species exist. In the 17th Century people started to ditch damp environments, such as bogs, to create a productive cultivated ground. Further ditches were made when the forestry gave large economical profits. The wetlands were impoverished from both groundwater and nourishment, and this led to a great loss of species.In a corporation with WWF and Skogsstyrelsen in Arvika, the University of Karlstad has participated in the Laskerudproject, a hydrological restoration-project in a forest landscape.
Mänsklig påverkan på mindre vattendrag i skogslandskapet : en inventering av vägtrummor och skyddszoner kring dessa i Uppsala län och norra Västmanlands län
Interference in an ecosystem means a disturbance. When harvesting, forest roads have to be
build to cope with heavy duty vehicles. Crossing brooks can not always be avoided. In this
case bridges or culverts have to be built. There are many different kinds of culverts and
depending on what type you choose and how you place the culvert, the watercourse and the
water organisms can be harmed in different ways.
Vattenkraft i Sverige : -Kartläggning kring miljöpåverkan, styrmedel och metoder på uppdrag av Statkraft Sverige AB
This paper aims to examine how and to what extent, a transition of Sweden according to the principles of Omställning Sverige (Transition towns Sweden), have the potential to contribute to a society with increased happiness.The paper is based on a qualitative textual analysis of the key texts in the Swedish Transition towns movement, Omställning Sverige. In the first part of the study the most important transition principles of Omställning Sverige were identified. Four key principles emerged: An altered view of economics, a spiritual change, a stronger local community and increased awareness. These transition principles were then analyzed through the lens of the scientific fields position on happiness, followed by a summarizing conclusion.The altered view of economics which Omställning Sverige advocates, where sustainability and quality of life are priorities over economic growth, is even necessary to secure our basic physiological needs. Such an economy has also improved conditions for economic stability, high employment and higher efficiency in the sense of happiness promoted in relationship to how many natural resources are used.
Autumn water sources for understory vegetation and fungi in a boreal forest : an evaluation using stable isotopes
Understory vegetation and fungi are regarded as important ecological drivers of processes like productivity and nutrient cycling in boreal forests. Whilst those processes are linked to soil water content, relatively little is known about the sources of soil water for these forest
components. During early autumn in boreal forests, temperature falls and large events of rain are frequent which may influence soil water availability. To better understand the autumn plant-soil-fungi water relationships in this ecosystem, I used stable isotopes techniques in this
study to examine the water sources for ericaceous shrubs and fungi in a Scots pine forest following a large, early autumn rain event. I hypothesize that ericaceous shrubs of two functional groups (evergreen vs.

Påverkas CSR-verksamheten av affärsmässiga intressen?
Kunder i dagens konkurrenstäta samhälle kräver mer eller mindre att företag tar ett ansvar gentemot samhället. Ansvarstagande av denna typ kallas, internationellt, för Corporate Social Responsibility (CSR). En entydig definition saknas, men övergripande talas det om att företag tar ekonomiskt, socialt, etiskt och miljömässigt ansvar. Genom att arbeta med denna typ av verksamhet visar företag att de verkar för kundernas intresse. Debatter pågår dock om företag gör detta för att stå sig i konkurrensen eller för att de verkligen eftersträvar ett hållbart samhälle.
Gestaltning av stadens utemiljöer - Naturlikt kontra formellt & abstrakt :
In the increasing urban environments and the
modern societies demands for sustainability
there is a challange in planning cities with a
balance between density and a satisfying access
of recreational environments. For attractive cities
these environments need to be designed to fit
every inhabitants? demands and opinions in some
way. Increased knowledge and understanding
is therefore needed about how different design
styles in landscape architecture affect people
and the cities. In this bachelor thesis benefits
and disadvantages as well as the experience
and impact of two fundamental design styles
i discussed; naturalistic and formal/abstract
design.
Hållbar vattenkraft i Nissan : En förstudie och konsekvensutredning över förutsättningarna för ökade vandringsmöjligheter med nya fiskvägar.
The hydropower from Nissan River is of national interest and produces annually 230 GWh from the twelve power stations in the main flow. For modified waters a consideration between the power production and the biological values has to be made. This reports serves as a pre-study for Nissans Vattenråd. It tries to evaluate some of the biological values in the Nissan basin and map the power production in the area. And the size and value of lost power production from new fishways for the twelve stations in the main flow.The investment of new fishways is calculated using simplified templates with values from the business.
Ekoturismens natur- och miljöpåverkan i polarområden
Tourism in the Arctic and Antarctic is increasing rapidly. In both Polar Regions, the cruise tourism is predominant. Several of the tour operators arrange trips under the banner of ecotourism, meaning that the trips should be ecologically sustainable. To ensure ecotourism standards there are different types of certifications; for cruise travels in the Arctic there is AECO (the Association of Arctic Expedition Cruise Operators) certification, and for travels to the Antarctic IAATO (the International Association of Antarctic Tour Operators). Promoters of ecotourism argue that these trips are important because they create support for conservation work among tourists making them ?polar ambassadors?.
När tågen slutat gå : förvandling av övergiven räls till publikt promenad- och parkstråk
Abandoned and unused railway structures often possess
great potential if they are reclaimed and reused for new
purposes. The thesis focuses on the global trend of
restoring and revitalizing these areas, converting them
into park areas, rail trails and green corridors in the city
landscape, while preserving their ecological, social, esthetic and historic values.
These rail areas were often abandoned when industries
moved out from the cities, either to industrial areas or
abroad. The use of railways for transporting industrial
goods was also replaced to a large extent my motorized
road vehicles in the mid 20th century, leaving the rails
under-utilized. Because of their location and intrinsic
values, they can be reused for important functions, such
as green areas in the city environment, providing space for
recreational activities and exercise and social meetings and
interactions.
I have closely investigated the three park areas High Line in New York, Promenade Plantée in Paris and Schöneberger
Südgelände in Berlin, which have all gone through this
transformation in recent years. I have summarized my
conclusions in three key concepts to consider: design for
social values, preserve the architectural history, and leave
room for future evolution.
The final part of my work is a design program for an
abandoned railways area in Stockholm: Eriksdal railway
area.

Bergsbrunna södra : analys och programförslag
This final project includes an analysis and a programme proposal for the
area Bergsbrunna södra. The area is situated along the railway between
Uppsala ? Stockholm, just south of Uppsala city. A new railway station is
planned here, which make the area attractive as residential area.
There are several values to take into consideration when developing an
area. An extensive analysis and valuation may define and protect different
characters and values, and also find the places most suitable to build
upon.
The area consists of three separate characters of landscape: the wide open
cultivated fields, the hilly wooden ground and the more varying little valley.
There are visual, cultural, social and ecological values to preserve.
The south part of the area is woods with high natural values that borders
to a national park in the natural forest of Lunsen.
