Abstract. Economic losses caused by hydrological extremes -floods and droughts -have been on the rise, worldwide. Hydrological extremes jeopardize human security and cause serious threats to human life and welfare and societal livelihood. Floods and droughts can undermine societies' security, understood as freedom from threat and the ability of societies to maintain their independent identity and their functional integrity against forces of change.Several dimensions of security are reviewed in the context of hydrological extremes. Floods and droughts pose a burden and serious challenges to the state, responsible to sustain economic development, societal and environmental security -the maintenance of ecosystem services, on which a society depends. It is shown that reduction of risk of hydrological disasters improves human security.

We formulated five proposals to improve specifications of flood hazard reduction projects and five proposals to preserve the river ecosystem functions, based on literature and authors' experience. Starting from these, we established a conceptual approach using the notion of riverscape, with related function richness and bioassessment tools.We defined four riverscape types based on the gradient of artificialness, from type I (impervious bed) to type IV (less than 30% or no artificial bed). To apply our approach to dry dam designs, we individualized different parts of dry dams and characterized them by an ideal riverscape type, according to the hydraulic constraints of each part.Type I is unavoidable in the bottom outlet, and types I or II at the foot of the dam.Types III (30% -50% of artificial bed) and IV were recommended at upper and lower parts of the dam, according to the risk of bank erosion and need for bank reinforcements. The approach appeared efficient to help biologists and hydraulic practitioners work together, and find technical solutions complying with both flood protection and biodiversity preservation requirement.

“…Solutions from this approach were not sustainable, because water problems are the result of multiple cause/effect dependencies. Efforts to compensate for anthropogenic modifications of the water cycle, resulting from catchment cover modification, urbanization, agriculture, overexploitation and pollution, for example, have not been successful (Kundzewicz, 1999). Second, solutions applied in developed countries up to now, based on civil engineering methods, are unsustainable because of financial and energy constraints (e.g.…”

The increasing human population and degradation of biological integrity of ecosystems has been expressed, to a great extent, as a decline in water resources, the most critical factor to achieve sustainable development. This is because overexploitation and degradation of the biotic structure alters ecosystem processes to the point at which the ecosystem ability to provide desired resources is seriously diminished. The progress in ecology during recent years has created a background for integration of ecology and hydrology. UNESCO, under the International Hydrological Programme 1HP-V, has initiated and provided a framework for such an interdisciplinary effort. During the programme, the conceptual background and principles of the surficial processes of ecohydrology were defined: first, by integration and quantification of biological and hydrological processes at the basin scale; second, by the enhancement of basin ecosystem absorbing capacity against human impact; and third, by using ecosystem properties as a management tool. Those principles are targeted, not only to eliminate threats, but also to amplify the opportunities for sustainable development as far as the control and regulation of nutrients and water cycling at the basin scale become possible. According to Popper's philosophy, the predictive planning of the future cannot be generated by extrapolating from recently used solutions. The integration of environmental sciences should create not only new scientific disciplines, but also a new solution which can face new challenges-sustainable management of the biogeosphere. Key words ecohydrology; water resources; sustainable development; ecosystems; hydrobiology; ecological engineering Ecohydrologie-la prise en compte de processus écologiques et hydrologiques pour la gestion durable des ressources en eau Résumé L'accroissement démographique et la dégradation de l'intégrité des écosystèmes ont pour conséquence, dans une grande mesure, un déclin des ressources en eau, facteur le plus critique vis à vis du développement durable. La raison en est que la surexploitation et la dégradation de la structure biotique altèrent les processus de l'écosystème à un point tel que l'aptitude de l'écosystème à produire les ressources désirées est sérieusement diminuée. Les progrès en écologie des dernières années ont produit une base pour intégrer l'écologie et l'hydrologie. L'UNESCO, à travers le Programme Hydrologique International PHI-V, a initié et fourni un cadre pour un tel effort interdisciplinaire. Durant le programme, le bagage conceptuel et les principes des processus supérieurs de l'écohydrologie ont été définis: premièrement l'intégration et la quantification des processus biologiques et hydrologiques à l'échelle du bassin versant; deuxièmement le renforcement de la capacité des écosystèmes du bassin versant à absorber les impacts anthropiques; et troisièmement l'utilisation des propriétés des écosystèmes comme outil de gestion. Ces principes sont identifiés, non seulement pour éliminer les menaces, mais aus...
