Abstract:
The present paper deals with five main structural levels of channel processes and channel patterns due to disconnectivity of fluvial processes. River braiding is related to existence of point, bar, channel (island), anabranching and large distributary channels (located in the deltas of large and largest rivers). Meandering is related to sinuosity of the flow and formation of complex loop and large meanders, the dimensions of which are larger than those corresponding to the water content of the river, and the meanders of the meandering belts. Due to the instability of the straight flow, the structural levels of the straight single channel are distinguished by their size: pool hollows on the riffles, reaches between adjacent bends and segments of braided channel, sections between single branches and stretched stretch areas along the bedrock banks or in the incised channel. Each structural level is related to the previous one forming scaling sequence (middle and side channels are the basis for the formation of branches and bends, etc.), representing genetic series, although in some cases they may have a different origin (intra-floodplain intercepts, relics of delta branches, etc.). The meandering process happens over various scales in both braided and straight channels. The formation of structural levels is governed by river size, geology, effective discharges and local drivers.

Abstract:
The context of urban rivers is one of pollution of their courses, the degradation of riparian habitats, the loss of biodiversity, and the marginalization of the human populations that live next to them. Due to urban growth, the hydrological dynamics in entire basins and the hydromorphology of rivers are changing. This situation increases flooding, decreases the availability of water for human use, and disconnects the rivers from the dynamics of the city. Agroforestry is the integration of cultural, wild, and domesticated diversity with use, conservation, and restoration objectives. These practices in cities can contribute to addressing the problems mentioned. We analyze agroforestry practices and the socio-ecological contributions to urban river rehabilitation. We review 37 experiences worldwide. Agroforestry practices included in the review are trees and hedgerows; wetland agroforestry; aquatic, botanical, edible, educational, and rain gardens; bioswales; green parking lots; food forestry; vegetation in alleys and streets; vertical terrace walls, among others. Agroforestry contributes to efforts to solve urban river problems, improve water quality and access, restore riparian habitats, enhance river hydromorphology, support local economies, and create a river culture. We emphasize promoting multi-relational people–river interactions based on theoretical and practical frameworks that integrate diverse disciplines, perspectives, and experiences.

Abstract:
With the formal adoption of the Water Framework Directive in 2000, into European legislation it committed all member states to ensure that all inland waterbodies should reach good ecological status by 2015. As a result examination of the influence of hydromorphology on the ecological health of riverine ecosystems has become an increasingly important priority for statutory monitoring agencies such as the Environment Agency of England and Wales and equivalents in other parts of the UK. It is anticipated that by increasing our understanding of the role that hydromorphological processes play in shaping river habitats and the ecosystems that they support, river management strategies can be developed that will help lead to waterbodies achieving good ecological status. In this thesis, the influence of river hydromorphology and instream channel management activities on instream macroinvertebrate communities is explored. A two-scale approach was used at a regional macro-scale and local / catchment micro-scale. The macro-scale study examines the ecological, hydrological and geomorphological data for 88 river reaches located within the Environment Agency , Anglian Central and Anglian Northern regions, over a twenty year period (1986-2005). At the micro-scale two sub-catchments were selected, the River Bain and River Lymn, both located in Lincolnshire, England for detailed investigation. The micro-scale study was undertaken using ecological, hydrological and geomorphological data collected over three successive seasons (Autumn 2008, Spring 2009 and Summer 2009) enabling the seasonal variations and the influence of both stream size and habitat biotope on macroinvertebrate community composition and structure to be explored. The hydromorphological characteristics and condition of the rivers were quantified using ecologically relevant hydrological indices, calculated from flow discharge paired with geomorphological indices from River Habitat Survey data. The response of the instream macroinvertebrate communities was examined using a range of ecological indices including the Lotic-invertebrate Index for Flow Evaluation (LIFE). The results of the macro-scale investigation demonstrate that the macroinvertebrate community is directly influenced by instream hydromorphology and the level of anthropogenic modification. The micro-scale study highlights important differences in macroinvertebrate communities associated with instream habitat / biotope composition. The quantification of river hydromorphology, with the use of ecologically relevant hydrological indices and geomorphological indices, derived from River Habitat Survey data, is discussed with regards its ability to help explain the structure and composition of macroinvertebrate communities within highly managed /regulated riverine ecosystems. The implications of this research for river managers and for implementing river restoration and rehabilitation schemes are explored.

Abstract:
River hydromorphological characterization is an important requirement for modern river management. The process-based river characterizations which are well established in fluvial geomorphology are location-specific and highly demanding in terms of resource and expertise, and their routine application for regional or national river characterizations is not feasible at the present. Reviewing current understanding of river geomorphic processes and making use of novel datasets, such as DEM, and tools, such as GIS, this work tests the feasibility of providing characterizations of hydromorphology that require moderate resources and are potentially applicable at regional or national scale. A framework to characterize river hydromorphology from specific map derived geomorphic controls (namely channel gradient, bankfull flow, specific stream power, Strhaler stream order and degree of channel confinement) is successfully developed. These controls are shown to be important in the characterization of channel types, to be consistently inter- connected in a hierarchical framework, and to affect frequency and typologies of channel forms. Stream power emerges as a dominant driver of sediment transport and floodplain formation and as an important indicator for characterizing channel sensitivity to erosion and deposition. The proposed characterization of hydromorphology uses automatic procedures of GIS and statistical analysis and demonstrates that these are promising for regional applications. Our understanding of the links between hydromorphology and ecology are also limited. This thesis presents an application of structural equation modelling (SEM) to explore the ecology of benthic macroinvertebrate communities in riverine ecosystems using national-scale biological, water quality and physical habitat data. The statistical model identifies a nurnber of links between the degree of organic pollution, alkalinity, physical habitat conditions, and the distribution of benthic macro invertebrates. SEM develops a confirmatory approach that it requires a-priori, explicit III ---= formulations of cause-effect relationships at the model conceptualisation stage. SEM is shown to address a number of the challenges related to multicollinear datasets (common in ecology), where interpretations based on statistical association alone can be problematic. IV

Abstract:
L'Orge est une petite rivière de plaine fortement segmentée, du bassin parisien. En 2010, elle comptait en moyenne un clapet tous les kilomètres sur sa partie aval. Pour rétablir la continuité écologique du cours d'eau, le Syndicat de l'Orge efface progressivement ces ouvrages. L'objet de cette thèse est le suivi biogéochimique, hydro-sédimentaire et écologique d'un bief de l'Orge de 6 km où 3 clapets consécutifs ont été effacés.Les hauteurs d'eau dans la rivière ayant baissé, des bancs de vase ont été mis à l'air. Ces banquettes de sédiments subissent des séquences d'inondation/exondation au rythme des crues. Les transformations de l'azote et du soufre y sont particulièrement actives et dynamiques. Cependant, les faibles flux d'eau échangés (modélisation) limitent l'impact des banquettes sur la rivière. Des processus intenses de précipitation/solubilisation des sulfates, liés aux variations des niveaux d'eau, ont une importance non négligeable sur la dégradation de la matière organique et la production d'ammonium dans la banquette.La capacité de transport de sédiments de la rivière a fortement évolué suite aux effacements, ce qui se traduit par l'apparition d'une granulométrie plus grossière en fond de lit. Ont été évalué la nouvelle vitesse de transit des particules charriées et le temps nécessaire pour atteindre un nouvel équilibre du lit et des espèces biologiques qui y vivent. Les indicateurs biologiques montrent que les effacements améliorent l'habitabilité de la rivière.Ces suivis montrent l'impact positif des effacements de barrage sur une rivière de plaine, même si un suivi dans la durée reste nécessaire pour confirmer les évolutions mises en évidence.

This study aimed to evaluate the stream hydromorphological Guaraíra through the Bavarian method. The basin of the creek is located within the catchment area of Gramame, the southern portion of the state of Paraíba. Therefore, the creek was divided into 47 sections of 100 meters. During the survey of the characteristics of the stream was possible to observe the level of anthropogenic modification along its route. These surveys take into account the dynamics of river and plain and with the junction of the dynamics is obtained modification degree ranging from 1 (no change) to 7 (completely changed), based on the use of the method Bávaro. The creek Guaraíra has 81% of its route unchanged, despite being in a watershed with 33.63% of its area modified crops of sugar cane and pineapple. The 19% change were due to engineering works and, as previously mentioned, sugarcane also influenced this change in the natural state. With the method, it is clear that investments for restoration of local anthropogenic are more effective due to the division of the stream in patches. Thus, save yourself money and time by acting at the core of the problems.
Este trabalho teve como objetivo a avaliação hidromorfológica do riacho Guaraíra, através do método Bávaro. A bacia hidrográfica do riacho está localizada dentro da bacia hidrográfica do Gramame, porção sul do Estado da Paraíba. Para tanto, o riacho foi divido em 47 trechos de 100 metros. Durante o período de levantamento das características do riacho foi possível observar o nível de modificação antrópica ao longo de seu percurso. Esses levantamentos levaram em consideração as dinâmicas do rio e da várzea e com a junção das dinâmicas se obtém o grau de modificação que varia de 1 (inalterado) a 7 (completamente alterado), a partir da utilização do método Bávaro. O riacho Guaraíra possui 81% do seu percurso inalterado, apesar de estar em uma bacia hidrográfica com 33,63% de sua área modificada pelas culturas da cana de açúcar e do abacaxi. Os 19% de alteração foram devido, a obras de engenharia e, como já citado anteriormente, a cana de açúcar também influenciou nessa alteração do estado natural. Com o método, fica claro que investimentos para restauração de locais antropizados são mais eficazes, devido à divisão do riacho em trechos. Dessa forma, economizam-se recursos financeiros e tempo agindo no cerne dos problemas.

Abstract:
Les cours d’eau et leurs bassins versants sont des systèmes complexes et en équilibre dynamique. Si l’on connait qualitativement assez bien la plupart des processus dont ils sont le siège (ex. transport de matière organique et de sédiments, transformation des litières, etc…), il est beaucoup plus difficile d’en avoir une représentation pertinente à la bonne maille compte tenu de l’emboitement d’échelles des processus, des déterminants terrestres agissant sur les milieux aquatiques et surtout des différents facteurs de stress qui s’y combinent. Nous avons mené une exploration dont le but était de rechercher les causes souvent multiples de dégradation de l’état écologique, d’en connaître l’étendue spatiale et la gravité, pour être en mesure de recommander des actions efficaces de restauration. Dans la première partie de cette thèse, nous avons développé des modèles explicatifs de l’état écologique à large échelle capables de donner des réponses applicables aux échelles de décision et de gestion, à savoir européenne, nationale et régionale avec comme objectif principal de comparer les relations entre les pressions combinées représentées par l’occupation du sol et l'état écologique des cours d’eau de quatre pays européens: la France, la Slovaquie, l'Estonie, et le Royaume-Uni (Angleterre et Pays de Galles). Cette étude a permis (i) d’établir une hiérarchie des catégories d’occupation du sol influant sur l'état écologique, en particulier l'agriculture et l'urbanisation, (ii) d’identifier des tendances régionales dans ces relations pression-impact et (iii) d’évaluer le poids relatif de la pression à l‘échelle du bassin et du corridor rivulaire, et l’effet tampon des zones rivulaires suivant la nature de leur couverture. Dans une deuxième partie, nous avons construit un corpus de modèles capables d’expliquer d’une part la variabilité des indices biologiques utilisés dans les réseaux et de prédire d’autre part l’état écologique des masses d’eau françaises non suivies par le réseau de contrôle et de surveillance (RCS). Cette étude a permis de montrer que : (i) le facteur le plus impactant pour l’état biologique qu’il soit mesuré à partir des macroinvertébrés, des poissons ou des diatomées était la physico-chimie, suivie de l’occupation du sol et de l’hydromorphologie et (ii) l’utilisation de ces trois types de pressions permettait de développer des modèles prédictifs de l’état biologique robustes et fiables. Dans une troisième partie, nous avons voulu tester si les relations entre les pressions à l'échelle locale et l'état écologique étaient hiérarchiquement influencées par la typologie régionale (basée sur les caractéristiques géographiques naturelles et les forces motrices). Ceci nous a permis de montrer que la prise en compte d’une typologie basée sur les forces motrices des bassins versants ne remettait pas en cause la hiérarchie des effets des pressions sur la biologie. Enfin, dans une quatrième et dernière partie, nous avons développé une approche nouvelle qui propose de prendre en compte les connaissances sur l’organisation des échelles et sur les liens entre pressions et état écologique, en construisant et en analysant un modèle structurel qui a permis de relier entre elles des variables latentes correspondant aux pressions d’occupation du sol, hydromorphologiques et physico-chimiques et d’analyser in fine leur effet sur l’état écologique mesuré ici à travers l’I2M2. Le développement de ce modèle a montré : (i) l’effet important de l’occupation du sol sur l’hydromorphologie et sur la physico-chimie et l’effet indirect qui en découle sur les macroinvertébrés, (ii) l’effet de l’hydromorphologie sur la mosaïque de substrats, la dynamique des nutriments et de la matière organique, impliquant un effet indirect majeur sur les macroinvertébrés
The rivers and their watersheds are complex systems in dynamic balance. If processes acting in stream are relatively well known (organic matter and sediment transport, litter degradation, etc ...), it is much more difficult to have a relevant representation of this functioning considering the hierarchy of scales, land determinants affecting aquatic environments and combined multiple stressors. We conducted an exploration whose purpose was to seek the multiple causes of degradation of the ecological status, to know the spatial extent and severity and to be able to recommend effective restoration actions. In the first part of the thesis, we developed large-scale models, based on existing data, to give answers applicable to the decision and management scales, i.e. European, national and regional. The main was to compare the relationships between the combined pressures represented by land cover and the ecological status of running waters in four European countries: France, Slovakia, Estonia, and UK (England and Wales). This first study allowed us i) to establish the hierarchy of the major influences that impact ecological status, particularly agriculture and urbanisation, ii) to identify regional patterns in these pressure-impact relationships and iii) to evaluate the relative weight of the pressures acting at the basin and riparian corridor scales, and the possible buffering effect of riparian land cover. In the second part of the thesis, we built a corpus of models capable of explaining the variability of the biological indices used in the survey network and also predict the ecological status of non-monitored water bodies in France. This permits to demonstrate that : (i) the parameters characterizing the load of nutrients and organic matter had a predominant effect on the three compartments, followed by land use and hydromorphology, (ii) it is possible to build models capable of predicting ecological status that are efficient and easily transferable, using data of different scales that influence the functioning of hydrosystems. In the third part, we tested if the relationships between local scale pressures and ecological status are hierarchically influenced by regional patterns (such as natural physiographic and/or driving forces). Introducing hierarchical factors in multi-stress models can lead to slight variations in responses of organisms to pressures according to their natural characteristics and their driving forces acting at catchment scale. And in the last part, the purpose of our approach was to take into account the nested scale organisation and the links between anthropogenic pressures and river ecological status by building - and analysing the results of - a model based on the PLS path modelling method. This method can be used to simultaneously analyse the effects of latent variables corresponding to land-use, hydromorphological and physico-chemical pressures on the ecological status of rivers, synthetically measured in this study by the macroinvertebrate-based French biotic index for wadeable rivers (I2M2). The development of this model should allow us to demonstrate : (i) the importance of land use effect exerted on both hydromorphology and physico-chemistry and their translation as an indirect effect on biological condition of streams, (ii) that hydromorphological alterations had an effect on substrates structure and nutrients and organic matter concentrations implying that hydromorphology has a major indirect effect on macroinverteb
