This thesis explains the relationships between the British Expedition to China, the Qing state, and the Chinese maritime and river population during the Opium War (1839-1842). Drawing on scholarship on borderlands and frontiers as well as a variety of textual and visual sources, the thesis argues that the Opium War transformed vast coastal and waterway regions in Guangdong, Fujian, Zhejiang, and Jiangsu provinces into what can be conceptualized as "water borders." These water borders were initially characterized by the existence of the Qing Empire's sea frontier, where the Qing rulers, with the "inner-outer paradigm" in mind, strove to maintain control over those labeled as "outer barbarians," "Han evildoers," "villainous fishers," and the "Dan." The rise of a British wartime frontier in China and its adverse effects on local transportation as well as Chinese regional and international trade, however, destabilized southeast China's socioeconomic order. With the Qing forces weakened, Chinese piracy was unleashed, and given limited British naval power, there was an absence of any militarily hegemonic power in southeast China's waters. The British occupation and naval blockade, moreover, resulted in the emergence of overlaps and interstices of the Qing and British empires. On the one hand, the British Expedition and the Qing state conflicted over managing Chinese merchant craft and their trade. On the other hand, subject to neither Qing nor British control, many Chinese people living along the coast and rivers took advantage of the wartime opportunities and expanded their activities and networks to fissures of Qing control and the newly opened interstitial space. The thesis engages with Opium War studies by 're-reorienting' the war toward the coast and revealing the war's three "inner" aspects, namely the Qing efforts to "tame" the sea frontier, British rule in wartime China, and the Qing-British conflicts over controlling Chinese littoral people. The thesis, moreover, contributes to scholarship on late imperial and modern Chinese littoral societies. It argues that while the war marked the beginning of an unprecedented-scale interaction of Chinese coastal and riverine people with Westerners in China, the evolution of Chinese littoral societies during the war was in fact a continuation of the preceding centuries. The Opium War, the thesis argues, brought about one of the most dramatic political-social upheavals in late imperial littoral China. Furthermore, the thesis revisits British imperialism in late imperial and modern China by looking at the origins of the British "formal empire," limitations of British power, and wartime aids of the "indigenous" population for the British. The thesis also reassesses the significance of the Opium War in the history of the Qing Empire. It argues that for the Qing state, its anti-opium campaign and anti-British war in 1839-1842 constituted one of the recurrent threats on the maritime frontier for the empire's first two centuries. It also highlights some aspects of similarities and linkage of the Qing Empire's maritime and inland borders. Furthermore, the thesis reevaluates the Qing's state capacity during the Opium War and in the following years, highlighting its partial ability to control the empire's littorals. Last but not least, the water border framework constructed in the thesis serves to underscore some aspects of continuity in the political and socioeconomic development of late imperial southeast China, and to facilitate comparison between different frontiers in the Qing Empire, Southeast Asia, and beyond.

Les travaux de cette thèse visent à mettre en place une gestion prédictive sous incertitudes de la ressource en eau pour les réseaux de voies navigables. L'objectif est de proposer un plan de gestion de l'eau pour optimiser les conditions de navigation de l'ensemble du réseau supervisé sur un horizon spécifié. La solution attendue doit rendre le réseau résilient aux effets probables du changement climatique et aux évolutions du trafic fluvial. Dans un premier temps, une modélisation générique d'une ressource distribuée sur un réseau est proposée. Celle-ci, basée sur les processus décisionnels markoviens, prend en compte les nombreuses incertitudes affectant les réseaux considérés. L'objectif de cette modélisation est de couvrir l'ensemble des cas possibles, prévus ou non, afin d'avoir une gestion résiliente de ces réseaux. La seconde contribution consiste en une distribution du modèle sur plusieurs agents afin de permettre son passage à l'échelle. Ceci consiste en une répartition des capacités de contrôle du réseau entre les agents. Chaque agent ne possède ainsi qu'une connaissance locale du réseau supervisé. De ce fait, les agents ont besoin de se cordonner pour proposer une gestion efficace du réseau. Une résolution itérative avec échanges de plans temporaires de chaque agent est utilisée pour l'obtention de politiques de gestion locales à chaque agent. Finalement, des expérimentations ont été réalisées sur des réseaux réels de voies navigables françaises pour observer la qualité des solutions produites. Plusieurs scénarios climatiques différents ont été simulés pour tester la résilience des politiques produites. / The work of this thesis aims to introduce and implement a predictive management under uncertainties of the water resource for inland waterway networks. The objective is to provide a water management plan to optimize the navigation conditions of the entire supervised network over a specified horizon. The expected solution must render the network resilient to probable effects of the climate change and changes in waterway traffic. Firstly, a generic modeling of a resource distributed on a network is proposed. This modeling, based on Markovian Decision Processes, takes into account the numerous uncertainties affecting considered networks. The objective of this modeling is to cover all possible cases, foreseen or not, in order to have a resilient management of those networks. The second contribution consists in a distribution of the model over several agents to facilitate the scaling. This consists of a repartition of the network's control capacities among the agents. Thus, each agent has only local knowledge of the supervised network. As a result, agents require coordination to provide an efficient management of the network. An iterative resolution, with exchanges of temporary plans from each agent, is used to obtain local management policies for each agent. Finally, experiments were carried out on realistic and real networks of the French waterways to observe the quality of the solutions produced. Several different climatic scenarios have been simulated to test the resilience of the produced policies.

Seen from abroad, Tokyo appears as a huge, vibrant metropolis where 21st-century Japan meets the traditional side of the country. Tokyo´s skyline is a diverse jumble of traditional houses and shrines, and modern architecture from skyscrapers of glass to 1970´s living capsules. Since the beginning, Tokyo has had great prerequisites for creating a city with amazing urban environment. Water was the first reason for people to settle down in Tokyo Bay. During Edo period (1603 – 1867), Tokyo was always described as a picturesque city with well-planned hydrology and a harmonic relationship with nature. With its canals full of water, it was a city comparable to Venice. The distribution and exchange relied almost entirely on water transport. With the expansion of the city, the water system had to be upgraded, which led to creating a complex network of waterways. Unlike in Western countries, where the economic, social and cultural life of the city developed around rather formal places as plazas and squares, in Japan, the lifeblood of the city developed in close connection with the water and nature. These places, also known as “meisho” (名所, lit. “famous places”) used to be linear open structures such as streets, river shores and bridges. During the transformation of Tokyo into a modern capital, the city cut many ties with the past. The unused canals suddenly became redundant and started belonging to the “wrong” side of the city. By the 1980s, many of the waterways were so polluted that the government began filling them up or covering them with elevated highways in preparation for the 1964 Tokyo Olympics. The modernization and its transformation also meant that most of the network of “meisho” and greenery have disappeared. “From dameisho to meisho” is inspired by series of woodblock prints “One Hundred Famous Views of Edo” (名所江戸百景, Meisho Edo Hyakkei) completed by the Japanese artist Hiroshige Ando (1797–1858), depicting a matrix of famous public spaces in Tokyo. My project examines the possibilities of recasting “meisho”, a spatial representation in Japanese culture, into a new, modern context via editing different layers of the city and its fabric. It explores linear, thread-like spaces such as Edo waterways, its transformations roads, as well as recently built elevated highways in order to search for contaminations and new collaborations, unexpected conditions and create new, green urban stitches. As one of the tackling tools, the project also looks at demographic trends shaping Japan and benefits from aging society and shrinking Japanese population. Last but not least I investigate ways of graphical reinterpretation of the series of woodblock prints using Tokyo and its new “meisho” spaces as a rolemodel.

Den svenska vattenkraften står för nästan 50 % av landets elproduktion vilket gör dess konstruktioner till en viktig del av samhällets infrastruktur. För att ett vattenkraftverk ska fungera effektivt och säkert ställs höga krav på komponenternas funktion och kondition. I dagsläget genomförs därför rutinmässiga kontroller på, i och runt dessa anläggningar. För de aggregatnära inre vattenvägarna genomförs detta ca vart åttonde år i samband med reparationer av turbinerna, vilka då måste tömmas på vatten. För till- och utloppstunnlarna, som ofta är drivna i berg, finns det dock inte några sådana rutiner. Detta i kombination med att majoriteten av Sveriges vattenkraftverk har uppnått en ålder på över 50 år gör att branschen har börjat bli intresserade av att få kännedom om skicket på tunnlarna. Att genom-föra inspektioner genom att torrlägga dessa är dock en tidsödande process som kräver att kraftverket är avstängt under en lång tid och därmed ger en stor ekonomisk förlust för ägaren. Detta arbete har därför utförts med syfte att utvärdera till vilken grad inspektioner med undervattensfarkoster, ROV, kan användas som alternativ till inspektioner av inre vatten-vägar, både aggregatnära och i till- och utloppstunnlarna. En litteraturstudie har genomförts, om vattenkraftverk, vanliga skador, dagens inspektionsmetoder samt hur en ROV är uppbyggd och fungerar. Arbetet innefattar även tre praktiska moment bestående av deltagande på en inspektion av torrlagda aggregatnära inre vattenvägar och en inspektion med ROV i en 2,5 km lång utloppstunnel samt egna försök med inhyrd ROV för att undersöka vilka typer av betongskador som är möjliga att detektera. Resultatet från samtliga delar i arbetet pekar på att besiktningar med ROV kan övervägas för flera olika typer av inspektioner. För till- och utloppstunnlar är denna typ av inspektion många gånger den enda rimliga. För de aggregatnära inre vattenvägarna ger dagens inspektionsmetoder med torrläggning ett fullgott resultat, men ROV skulle kunna vara ett alternativ vid svårtillgängliga delar, t.ex. på grund av utformning eller stora läckage. / Swedish hydro power accounts for nearly 50 % of the country's electricity production which makes the constructions within this production system an important part of the societal infrastructure. To ensure safe and efficient operation of these hydroelectric power plants high demands are put on the components function and condition. Therefore, routine inspections are carried out inside and around these facilities. For the waterways directly connected to the power station, such as penstocks, wicket gates and draft tubes, these checkups are made about every eight years simultaneously as planned repairs of the turbine, when the waterways have to be emptied. For the head and trail race tunnels, which often are driven in bedrock, there are no such routines. This, in combination with the fact that the majority of the Swedish hydroelectric plants have attained the age of over 50 years, has led to an increased interest within the industry in ways to increase their knowledge about the condition of these water passageways. To conduct inspections by draining the tunnels is however a very time consuming process that requires the power plant to be turned off for a long time causing a major financial loss for the owner. The purpose of this master thesis is to assess the extent to which inspections with remotely operated vehicles, ROV, can be used as an alternative method for inspections of covered waterways, both those close to the power house and the head and tail race tunnels. A literature study of hydro power plants, common damages, current inspection methods and the construction and function of an ROV, has been conducted. The method also includes three practical activities, participation at inspections in drained waterways and at an ROV inspection of a 2.5 km tail race tunnel. Furthermore, tests with a rented ROV were carried out to investigate what type of concrete damages that are possible to detect using this method. The result from all parts in this thesis indicates that examinations by ROV can be considered for several types of inspections. For head and tail race tunnels, this type of inspection is often the only reasonable method. For the waterways directly connected to the power station, current inspection methods by draining show good result. But the ROV could here be an alternative in inaccessible areas, for instance due to waterway design or heavy leakage for instance.

Thesis "Consumer Protection in transport in EU legislation" deals with consumer protection in specific areas. This thesis defined the rights and obligations of air passengers, rail transport, bus and coach transport and consumer protection when traveling by sea and inland waterways. The thesis is also exploring the awareness of EU citizens of their rights by the European Commission - Eurobarometer. Thesis is processed by analysis and comparison of selected judgments of the Court of Justice of the European Union and EU legislation.

Europäische große Flüsse wurden über Jahrhunderte entscheidend verändert und zu Wasserstraßen für die Schifffahrt ausgebaut. Flussregulierung, Begradigung und Hochwasserschutz tragen zu multiplen Stressoren bei, wobei die Schifffahrt bislang keine Beachtung als potentieller zusätzlicher Einflussfaktor (Stressor) fand. Die zentrale Fragestellung dieser Arbeit befasste sich mit der Rolle der Schifffahrt zwischen multiplen Stressoren und deren Auswirkungen auf die Fischgemeinschaften großer Flüsse. Hierzu wurde die „Large River Fish Database“ (LRDB), ein weltweit einzigartiger Datensatz zusammengestellt, der 2693 Befischungen an 358 Probestellen in 16 europäischen großen Flüssen enthält. Die Probestellen sind durch verschiedene Einflussfaktoren (Stressoren) und Schiffsverkehr beschrieben. Um ein für große Flüsse repräsentatives Abbild der Fischgemeinschaften zu erhalten, wurden zunächst die angewendeten Fischfangmethoden analysiert. Mit der Elektrofischerei wurden die höchsten Fischdichten und die höchste Biodiversität erfasst. Die Elektrofischerei ist daher für eine repräsentative Erfassung der Fischgemeinschaften großer Flüsse geeignet und wurde für weitere Analysen ausgewählt. Die kommerzielle Frachtschifffahrt trat als einer der einflussreichsten Stressoren hervor, zusammen mit erhöhter Fließgeschwindigkeit und dem Verlust von Überschwemmungsflächen. Dichten von insbesondere Habitat-sensitiven Fischen sanken bereits ab acht Frachtschiffen pro Tag signifikant ab. Darüberhinaus hatte auch die Freizeitschifffahrt (Flusskreuzfahrten und motorisierte Sportboote) deutliche und zu Frachtschiffen unterscheidbare ökologische Konsequenzen. Die Wirkungen der Schifffahrt sind ebenso verheerend wie die der hydromorphologischen Degradierung und benötigen eine gesonderte Beachtung im Flussmanagement und der Flussrevitalisierung. Freizeitboote und Flussdampfer wirken der Flussrenaturierung kleinerer Wasserstraßen entgegen und gefährden den ökologischen Erfolg des Blauen Bandes. / European large rivers have been tremendously modified over centuries and transformed into waterways for inland navigation. Extensive river modifications such as river regulation, channel straightening and flood protection have resulted in multiple pressures. However, inland navigation has not been considered as a potential pressure yet. This thesis aimed to assess the role of inland navigation among the most prevailing pressures in large rivers under field conditions. A worldwide unique and complementary dataset, the Large River Fish Database (LRDB) was compiled. The LRDB consists of 2693 fish samples assessed at 358 sampling sites in 16 European large rivers. Sites were characterized by various pressure variables and frequencies of ship traffic. To derive representative samples of large rivers fish assemblages, performance of various fishing gears applied was assessed. Electrofishing samples represented highest densities of fish and highest overall biodiversity. Therefore, electrofishing is suitable for fish-based assessments of large rivers and only electrofishing samples were selected to assess multiple pressures and inland navigation. Commercial cargo navigation appeared as the most influential pressures on large rivers fish assemblages among increased velocities and the loss of floodplains. Starting at already eight passing vessels per day, densities of particularly habitat-sensitive spawners significantly declined. Moreover, recreational navigation such as river cruises and motorized sport boats had distinct ecological consequences to those of cargo vessels. Inland navigation is as detrimental as the hydromorphological degradation of the river channel and requires specific attention in river management and rehabilitation. Pleasure boating (river cruises and sport boats) will counteract river rehabilitation also in smaller waterways and delimit ecological success of the Blue Band initiative in Germany.

The subject of this thesis is a socio-economic assessment of the investment project. In the theoretical part I discuss what is a project, evaluation of public projects, methods of evaluating the economic efficiency of public projects, evaluation of the efficiency of investments in waterways using the CBA method, economic performance indicators and sensitivity and risk analysis. In the practical part, I develop a case study on a specific project, where I focus on the development of financial analysis, economic analysis and sensitivity analysis on all project options.

Vattenkraftens påverkan på rinnande vatten är välbeskriven i litteraturen. Med ökat intresse för vindkraft och andra energislag med begränsad klimatpåverkan, ökar även behovet av reglerkraft. Effekten av korttidsreglerad vattenkraft på ekosystem är ett aktuellt ämne med kunskapsluckor i stort behov av fler studier. Indalsälven passerar Järkvissle kraftverk några mil norr om Sundsvall. Den lokala harrpopulationen har minskat kraftigt och misstankar finns om kopplingar till korttidsregleringen i Järkvissle kraftverk. Vid förvaltning av ekosystem och djuren i dem är kunskapen om interaktioner och beteenden bland det viktigaste att etablera. Detta för att kunna avgöra om artens beteende påverkas av korttidsreglering. Bristande kunskap om lokala lekbeteenden innebar således att harren nedan Järkvissle kraftverk studerades inför förväntad lekperiod. Studien baserades på två antaganden 1) harr förflyttar sig uppströms mot grundområden, lämpade för lek, när vattentemperaturen ökar. 2) harr är mer aktiv när flödesvariationen är hög, eftersom lekplatsernas beskaffenhet påverkas av flödesförhållanden. Harr (n = 20) från sträckan nedan Järkvissle kraftverk märktes med radiosändare, för att studera rörelsemönster och beteenden i anslutning till lek under perioden 28 april till 29 maj 2022. Vid 24 handpejlingstillfällen registrerades de märkta individernas position och djup. En Multipel linjär regression med bakåtvänd eliminering gav tre signifikanta resultat. Det observerades en ökad aktivitet i form av euklidisk förflyttning vid höga flöden motsvarande en förflyttning om 1,0 m (± 1 m) för varje 1,0 m3 s-1 ökat flöde. Det observerades även ett temperaturberoende val av ståndplats där en ökning om 1,0 ºC resulterade i en förflyttning till en ståndplats som var 0,21 ± 0,03 m grundare, på ett avstånd som var 65,2 ± 12,5 m längre bort från dammen. Studien bör kompletteras med kartläggning av optimala värden för flödesförändring som gynnar harr, samt om det finns andra variabler som bättre kan förutse tidpunkt och plats för lek. Om avsikten är att stoppa minskandet av harrbeståndet i Järkvissle, bör Järkvissle kraftstation övervaka vattentemperatur och anpassa sin flödesregim. Detta för mjukare övergångar mellan högt och lågt flöde samt att flödet hålls stabilt under lek med fyra extra veckors utrymme för inkubering. / The effect of hydroelectric powerplants (HEP) on waterways is extensive and has been well documented in the literature. But with an increased interest in wind power and other green alternatives, a higher demand for regulated hydroelectric power has emerged, so as not to put stress on the electric grid. Hydropeaking and its effect on ecosystems are a hot topic with gaps in knowledge calling for more research. Indalsälven runs through Järkvissle HEP a few miles north of Sundsvall. The local grayling population has seen a large decline and there are suspicions of a connection to the hydropeaking at Järkvissle HEP. When managing ecosystems and the animals within them it is vital to establish a firm understanding of interactions and behaviour. This can be used to determine the effect of hydropeaking on the behaviours of grayling. A lack in knowledge of local spawning behaviour thus led to a study of the grayling2population below Järkvissle HEP leading up to the expected spawning period. The study was based around two assumptions: 1) grayling move upstream towards shallower areas suitable for spawning as the temperature in the water rises, and 2) grayling are more active when the variation in flow is high, because the number of suitable spawning grounds are limited by flow. Graylings (n = 20) in the area below the Järkvissle HEP were tagged with radio transmitters, to study the movement and behaviour exhibited before the expected spawning period between April 28th and May 29th, 2022. On 24 occasions hand tracking was performed and position and depth of the marked individuals were recorded. Through a multiple linear regression with backwards stepwise elimination three significant results were found. There was an observed increase in activity in the form of Euclidean movement represented by a 1,0 m (± 1 m) movement for every 1,0 m3 s-1 of increased flow. We also observed a temperature dependency when it came to habitat choice, where an increase of 1,0 ºC in water temperature resulted in a movement to an area 0,21 ± 0,03 m shallower, at a distance that was 65,2 ± 12,5 m further from the dam. The findings of this study should be expanded upon with further research into optimal values for flow variation that best suit grayling, and additionally explore whether there are other variables to better predict time and place for spawning. If the intention is to stop the decline of the grayling population, Järkvissle HEP should monitor the water temperature and adapt their flow regime to make softer transitions between high and low flow and keeping the flow at a stable interval during spawning and an additional four weeks to leave room for incubation.

This thesis examines the water resource management in two Greek colonies in Magna Graecia, Akragas and Metaponto, and the relationship between resource management and political regimes. It asks how similar ancient urban theory was to the practical reality, and if different forms of government made different provisions for water management. Chapter 1 outlines urban and health theories found in the works of ancient theorists. It debunks the idea that Hippodamos was the inventor of grid planning, while introducing the concept of ‘total’ city planning. The focus of Classical scholarship on Athens necessitates discussions of several Athenian water systems and how resource management changed (or continued) through different governments in Athens as a point of comparison for Akragas and Metaponto. This chapter focuses on literary analysis and introduces the controversial Southeast Fountain House, with an in-depth consideration of the fountain’s naming and dating problems. Chapter 2 contains the case studies of Akragas and Metaponto and an exploration of the hydrogeology at the two sites, with an introduction to the hydrological phenomenon of karst activity. A discussion of their unique water features—the kolymbethra at Akragas and the canals in the chora of Metaponto—connects the deliberate planning that occurred in both cities to Hippodamos and the urban theorists. Chapter 3 more fully explores the role of tyrants and democracies in water management. Regardless of authorship, water resource management and water systems are necessary for any city, and so most tyrannical water infrastructure continued to be used and expanded and improved upon even under different governments. Even under tyranny water management is a provision of the state and is engaged with and managed by the citizens of the city. Water management is an essential part of siting and establishing a city, so that it is inseparable from urban planning. / Thesis / Master of Arts (MA)
