Die Bemessung von Bauwerken an oder in Fließgewässern erfordert die Kenntnis des statistischen Hochwasserregimes. Beispielsweise legen Hochwasserschutzkonzeptionen häufig ein Hochwasser zu Grunde, welches in einem Jahr mit der Wahrscheinlichkeit von 1/100 auftritt. Ein extremeres Hochwasser wird für den Nachweis der Standsicherheit großer Stauanlagen nach DIN 19700-12 mit einem Hochwasser der jährlichen Eintrittswahrscheinlichkeit von 1/10000 benötigt. Ein solches Hochwasser kann bereits wegen des instationären Klimas nicht allein aus Durchflussmessdaten abgeleitet, sondern lediglich idealisiert dargestellt werden. Das resultiert nicht zuletzt daraus, dass der Mensch natürlich Zeuge eines so unwahrscheinlichen Ereignisses werden kann. Jedoch kann er die Unwahrscheinlichkeit nicht nachweisen. Jedes Berechnungsschema, mit welchem ein so unwahrscheinliches Ereignis abgeschätzt werden soll, wird nur begrenzt zuverlässig sein. Das Ziel der Arbeit ist es daher, die Schätzung etwas zuverlässiger zu gestalten. Grundsätzlich gilt, dass ein Modell umso mehr bzw. sicherere Ergebnisse liefern kann, je mehr Daten in das Modell eingehen. Direkt mit dem Durchfluss gekoppelt sind Angaben zu historischen Hochwasserereignissen bzw. qualitative Einschätzungen kleinräumiger Ereignisse. Eine wichtige Datenquelle neben den Durchflussartigen ist der mit dem Durchfluss kausal verbundene Niederschlag und dessen zu vermutendes Maximum in einem Gebiet. Wird zusätzlich regional vorgegangen, können räumliche Aspekte und Strukturen in größeren Einzugsgebieten berücksichtigt werden. Diese stärken bzw. erweitern die lokalen Berechnungsgrundlagen und gewährleisten ein räumlich konsistentes Bild. Im Umkehrschluss kann das Durchflussregime regionalisiert werden, um Informationen an nicht bemessenen Orten bereitstellen zu können. Aus den genannten erweiterten Berechnungsgrundlagen lassen sich drei Anknüpfungspunkte schließen: (i) Es muss eine sehr flexible und dennoch plausible Darstellungsmöglichkeit des statistischen Niederschlagsregimes bis zum vermutlichen Maximum formuliert werden. (ii) Das entwickelte Niederschlagsregime muss mit dem Durchflussregime gekoppelt werden, um die Informationen nutzen zu können. (iii) Die anschließende Regionalisierung muss die verschachtelte baumartige Struktur hydrologischer Einzugsgebiete berücksichtigen. Punkt (i) wird durch eine zweigeteilte Verteilungsfunktion gelöst. Damit werden die ideale Darstellung des wahrscheinlicheren Bereiches und der plausible Verlauf bis zum Maximum miteinander verbunden. Bezüglich Punkt (ii) wird ein neues Kopplungsprinzip entwickelt. Dieses basiert auf der Annahme, dass ein je nach Gebiet gültiger maximaler Scheitelabflussbeiwert existiert, welcher asymptotisch erreicht wird. Im Ergebnis erhält die Durchflussverteilung mit der Abflussbeiwertapproximation einen oberen Grenzwert in Abhängigkeit von Niederschlagsmaximum und Scheitelabflussbeiwert. Entsprechend der Vorgaben in Punkt (iii) wird die Referenzpegelmethode entwickelt. Diese basiert darauf, dass ähnliche Einzugsgebiete äquivalente Hochwasserscheitel generieren. Damit können bekannte Hochwasserereignisse eines Referenzpegels auf unbeobachtete Teileinzugsgebiete übertragen werden. Bei der Wahl des Referenzpegels wird u.a. die Topologie der Einzugsgebiete berücksichtigt. Die gesamte Strategie kann auf große Untersuchungsgebiete angewandt werden. Am Beispiel sächsischer Flüsse wird die Vorgehensweise von der Datenhomogenisierung bis hin zum extremen Hochwasserdurchfluss an einem unbeobachteten Querschnitt erläutert. / The dimensioning of different constructions at and in streams respectively requires knowlegde on the flood situation at site. For instance flood protection concepts often base on a peak discharge of the annual recurrence probability of 1/100. A more severe flood of an annual recurrence probability of 1/10000 is used to confirm the stability of large dams following DIN 19700-12. Such a flood cannot be deduced from runoff data only, but rather shown in an idealised way. It results not least on the fact, that human can witness a very improbable flood event. But is it not possible to verify the improbability. Every modelling scheme that is confronted with the deduction of such an extreme flood event will be of limited reliability. The task\'s aim will therefore be to make the estimation more reliable. Generally the more data a model involves the more trustworthy the results will become. Directly coupled with runoff are historical flood data and qualitative details of small scale flood events respectively. Aside runoff information an important data source is precipitation data, which is coupled with runoff data in a causal way, and the possible maximum precipitation. If additionally whole regions are examined it is possible to consider regional facets and structures of larger catchments. These strengthen and expand local modelling basics and provide a regional consistent result. Vice versa the flood regime can be regionalised to gain information at unobserved cross sections. Out of the described expanded modelling basics follow three links: (i) It is necessary to find a flexible but still plausible formulation of the statistical precipitation regime until the probable maximum precipitation. (ii) The formulation of point i) has to be coupled with the flood regime to include these information. (iii) The adjacent regionalisation has to account for the nested and arboreal structure of hydrological catchments. Point (i) will be solved by a split distribution function. That allows the ideal display of the more probable domain as well as the characteristics until the probable maximum. Regarding point (ii) a new principle of coupling will be developed. It bases on the assumption that a regional maximum runoff coefficient exists and it will be gained asymptotically. As a result of the runoff coefficient approximation the runoff distribution function gets an upper limit depending on maximum precipitation and runoff coefficient. Respecting the guidelines in point (iii) the reference gauge method will be developed. It bases upon the fact, that likewise catchments generate equivalent peak discharges. For this reason it is possible to carry known peak discharges of a reference gauge onto unobserved subcatchments. Among other things the choice of a reference gauge accounts for the topology of the catchments. The whole strategy can be applied to large catchments what is exemplarily shown in Saxon streams. Beginning with a data homogenisation to the point of discharges of extreme low exceedance probabilities at unobserved cross sections the whole procedure is shown.

The Öresund Region is a historical cross border region working over the national borders of Sweden and Denmark. The regional administration, the Öresund Committee, is the only political forum that encompasses the whole region and serves its interests collectively. Not only is it cooperating with the national governments but also has a close relationship with the Nordic Council and especially with the European Union. According to a method developed by Liesbet Hooghe, Gary Marks and Arjan H. Schakel, it is possible to retrieve a Regional Authority Index which mirrors the formal authority of a region. The method is evaluated in accordance to the complications of the Öresund Region’s dual nationality and finds that the Öresund Committee has a rather concealed role with greater indirect impact than it is given credit for. However, in terms of formal authority, the Öresund Committee has a weak position and shares no rule with higher political entities, such as the Danish, Swedish and European central administrations.

This thesis examines regional integration in Southern Africa and the evolution of SADC. Regional developments are evaluated with the yardsticks of integration theory, against the background of international regionalisation, and in terms of the region's practical record, its rhetoric and future agenda. The extent to which economic integration is progressing, is determined, after which the thesis focuses on political integration within SADC - both de Jure and de facto. Finally, developments within the region are evaluated in light of normative prerequisites for increased political integration. The thesis finds that the integration process in SADC does not fit into traditional integration theory, and concludes that successful economic integration in the region is not necessarily a prerequisite to political integration, but would facilitate it. The research finally concludes that there is evidence of embryonic political integration within SADC, which will wane or grow depending primarily on the political will of its constituents / Political Science / M.A. (Politics)

Cette recherche s’intéresse aux impacts sociopolitiques des gazoducs et des oléoducsmis en oeuvre depuis 1991 au Caucase du Sud. S’appuyant sur un cadre théoriquemêlant principalement sociologie de l’Acteur-Réseau, sociologie éliasienne etapproches managériales, elle postule que la construction d’un système complexe detransport de pétrole et de gaz azerbaïdjanais est révélatrice de l’évolution de laconfiguration sud-caucasienne. Cette thèse étudie tout d’abord les interactions qui senouent autour de la mise en oeuvre des voies d’exportation des hydrocarburesazerbaïdjanais. Elle met en lumière l’émergence de nouvelles formes de régulation, dontla plupart profite à la compagnie pétrolière BP. Elle démontre ensuite comment lesréseaux sociotechniques construits autour de ces nouvelles voies participent d’uneévolution de la configuration sud-caucasienne. Ces réseaux débordent du cadrepurement économique pour aboutir au développement de la régionalisation entrel’Azerbaïdjan, la Géorgie et la Turquie. Cette recherche souligne enfin les gains queretire l’Etat-entreprise azerbaïdjanais de cette régionalisation fondée sur leshydrocarbures. Bakou se sert de ces derniers pour étendre son influence économique etpolitique au sein de la configuration sud-caucasienne. La sociologie de l’Acteur-Réseaunous permet donc de souligner le rôle non seulement économique mais égalementpolitique des hydrocarbures dans la montée en puissance de l’Azerbaïdjan qui, d’Etat enfaillite, est devenu puissance régionale. / This dissertation looks at the socio-political impacts of the pipelines that have beenimplemented in the South Caucasus since 1991. It is based on a theoreticalframework mixing Actor-Network Theory, Norbert Elias’s sociology andmanagement approaches. It assumes that the construction of an Azerbaijanihydrocarbons transportation complex system sheds light into the evolution of theSouth Caucasian configuration. First, this research studies interactions that emergeLUSSAC Samuel | Science Politique | Doctorat | 201114around the implementation of export routes for Azerbaijani oil and gas resources.It highlights the development of new forms of governance, which mostly benefit tothe oil company BP. Second, this dissertation demonstrates that the sociotechnicalnetworks built around these new export routes contribute to the evolution of theSouth Caucasian configuration. These networks overflow the economic sphere tofoster regionalization between Azerbaijan, Georgia and Turkey. Third, thisresearch underlines the benefits the Azerbaijani ‘state-company’ retrieves fromthis hydrocarbons-based regionalization. Baku takes advantage of oil and gasresources to increase its economic and political influence within the SouthCaucasian configuration. Therefore, the Actor-Network Theory helps to shed lightinto the economic and political role of hydrocarbons in the rise of Azerbaijan.From a failed state, this country has now established itself as a regional power.

L’action extérieure du Parlement écossais est l’objet de notre étude. D’abord, nous avons identifié la capacité opérationnelle de cette institution au sein du système institutionnel britannique, sur la scène communautaire et dans les échanges internationaux. Puis, nous avons détecté les facteurs structurant cette action. Selon notre étude, trois pôles prennent forme dans l’action parlementaire tels que les îles Britanniques, l’Europe qui couvre l’espace géographique européen, l’environnement institutionnel communautaire. Enfin, le troisième pôle est l’espace hors d’Europe, notamment les pays du Commonwealth et les Etats-Unis d’Amérique. Nous avons également établi une certaine spécialisation des méthodes et des moyens d’action dans les trois pôles évoqués. / The focus of my dissertation is the external action of the Scottish Parliament. My study identifies the operational capacity of this institution within the British institutional system, on the European Union arena and in international relations. I have identified the factors structuring the parliamentary action that shaped three poles such as the British Isles, Europe and outside the geographic European space. The pole of Europe covers both Continental Europe and the EC institutional environment. I have also identified the specialisation of methods and tools of action within the above mentioned poles

Water infrastructures have been implemented to support the vital activities of human society. The infrastructure developments at the same time have interrupted the natural catchment response characteristics, challenging society to implement effective water resources planning and management strategies. The Telemark area in southern Norway has seen a large number of water infrastructure developments, particularly hydropower, over more than a century. Recent developments in decision support tools for flood control and reservoir operation has raised the need to compute inflows from local catchments, most of which are regulated or have no observed data. This has contributed for the motivation of this PhD thesis work, with an aim of improving runoff estimation at ungauged catchments, and the research results are presented in four manuscript scientific papers.  The inverse distance weighting, inverse distance squared weighting, ordinary kriging, universal kriging and kriging with external drift were applied to analyse precipitation variability and estimate daily precipitation in the study area. The geostatistical based univariate and multivariate map-correlation concepts were applied to analyse and physically understand regional hydrological response patterns. The Sobol variance based sensitivity analysis (VBSA) method was used to investigate the HBV hydrological model parameterization significances on the model response variations and evaluate the model’s reliability as a prediction tool. The HBV hydrological model space transferability into ungauged catchments was also studied.  The analyses results showed that the inverse distance weighting variants are the preferred spatial data interpolation methods in areas where relatively dense precipitation station network can be found.  In mountainous areas and in areas where the precipitation station network is relatively sparse, the kriging variants are the preferred methods. The regional hydrological response correlation analyses suggested that geographic proximity alone cannot explain the entire hydrological response correlations in the study area. Besides, when the multivariate map-correlation analysis was applied, two distinct regional hydrological response patterns - the radial and elliptical-types were identified. The presence of these hydrological response patterns influenced the location of the best-correlated reference streamgauges to the ungauged catchments. As a result, the nearest streamgauge was found the best-correlated in areas where the radial-type hydrological response pattern is the dominant. In area where the elliptical-type hydrological response pattern is the dominant, the nearest reference streamgauge was not necessarily the best-correlated. The VBSA verified that varying up to a minimum of four to six influential HBV model parameters can sufficiently simulate the catchments' responses characteristics when emphasis is given to fit the high flows. Varying up to a minimum of six influential model parameters is necessary to sufficiently simulate the catchments’ responses and maintain the model performance when emphasis is given to fit the low flows. However, varying more than nine out of the fifteen HBV model parameters will not make any significant change on the model performance.  The hydrological model space transfer study indicated that estimation of representative runoff at ungauged catchments cannot be guaranteed by transferring model parameter sets from a single donor catchment. On the other hand, applying the ensemble based model space transferring approach and utilizing model parameter sets from multiple donor catchments improved the model performance at the ungauged catchments. The result also suggested that high model performance can be achieved by integrating model parameter sets from two to six donor catchments. Objectively minimizing the HBV model parametric dimensionality and only sampling the sensitive model parameters, maintained the model performance and limited the model prediction uncertainty.
