At present, humans appropriate more than half of the Earth's renewable and accessible water. This high demand for water resources comes at a cost: it puts an estimated 65% of global river discharge under moderate to high threat from anthropogenic drivers of stress. One way to alleviate some of this pressure is to develop and apply sustainable management practices to human activities that affect river systems. To develop best managements practices in this context require methods, data and scientific information that are specific to river systems. Given the interconnectedness of rivers over large spatial extents, sustainable management strategies need to be designed for basin, regional, or even global scales. Sustainable management is multifaceted and often requires drawing information from various disciplines. To advance the sustainable management of large river systems, we need information and data related to different research themes, and we need specific methods that reflect the connected and cumulative nature of river systems. In this thesis, I explore novel data and methods to advance three particular research themes that are closely related to sustainable river management, namely the natural flow regime paradigm, the representation of aquatic biodiversity through proxies, and the concept of hydrologic ecosystem services. I develop one global and three large-scale studies, each representing different contributions, including new data and methods, to the three themes. As an overarching approach to provide and analyze new baseline information, I first develop a multidisciplinary approach to river classification and use it to design a novel river reach typology at the global scale. I then explore this framework for river classifications at two regional scales, where I evaluate river classes (1) as a potential contribution to natural and environmental flow assessments in Canada, and (2) as proxies for fish assemblages in the Greater Mekong Region. Finally, in Canada, I quantify capacity for, demand for, and pressure from freshwater provision and regulation based on hydrological connectivity, and I design a composite indicator of risk to the provision of this hydrologic ecosystem service. The resulting river reach classifications at the global scale, in Canada, and in the Greater Mekong Region provide typologies that can facilitate freshwater conservation efforts and environmental assessments. They also provide a new avenue to support the integration of environmental flow requirements and fish assemblages in large-scale river management. The novel hydrological method to quantify freshwater ecosystem services can be used to design new, large-scale assessments of ecosystem services around the world that account for the connected and cumulative nature of river systems. This quantification also presents a first-time high-resolution mapping of the risk to freshwater provision and regulation in Canada. My conclusions discuss overarching findings from the thesis, including the importance of innovative statistical approaches, spatial hierarchy, and interdisciplinarity to further our understanding of large river systems.

520 $a A l'heure actuelle, les humains s'approprient plus de la moitie des ressources eau renouvelable et accessible de la Terre. Cette forte demande fait pression sur nos ressources hydriques. On estime que 65% du debit mondial est altere de facon modere a eleve par des stress anthropiques. Une facon d'attenuer certaines de ces pressions est de developper et d'appliquer des pratiques de gestion durable au sein des systemes fluviaux. La gestion durable est multidimensionnelle et necessite souvent de rassembler des informations provenant de diverses disciplines. Pour faire progresser la gestion durable des systemes fluviaux, nous avons besoin d'informations, de donnees et de methodes liees a differents themes refletant la nature cumulative de ces systemes. Dans cette these, j'explore des pistes d'integration vers les pratiques de gestion durable de trois de ces themes, a savoir le regime des ecoulements naturels, la biodiversite des eaux douces et les services ecosystemiques, en developpant des donnees et methodes pour trois etudes a grande echelle. J'ai developpe une approche multidisciplinaire de la classification des rivieres et je l'ai utilise pour concevoir une premiere typologie de segment de rivieres a l'echelle mondiale. Par la suite, j'ai applique cette approche pour deux classifications des rivieres a l'echelles regionales ou j'ai evalue (1) contribution potentielle a l'evaluation des besoins environnementaux au Canada des classes resultantes et (2) la possibilite d'utilise les classes de rivieres comme indicateurs des assemblages de poissons dans la Grande Region du Mekong. Enfin, au Canada, j'ai quantifie la capacite, la demande et les pressions decoulant de l'approvisionnement en eau douce en fonction de la connectivite hydrologique et j'ai concu un indicateur composite de risque pour ce service. Les classifications qui resultent a l'echelle mondiale, au Canada et de la Grande Region du Mekong, fournissent des typologies qui peuvent etre utiles pour les efforts de conservation des milieux aquatiques et les evaluations environnementales. L'approche hydrologique de la quantification des services ecosystemes peut etre utilisee pour concevoir de nouvelles evaluations a grande echelle des services ecosystemiques a travers le monde coherentes avec la realite des systemes fluviaux. Les conclusions tirees de ma these traitent de l'importance des approches statistiques innovatrices, de la hierarchie spatiale et de l'interdisciplinarite comme outil pour approfondir notre comprehension des grands systemes fluviaux.
