Texte intégralRoad traffic collisions, a global public health and socio-economic concern, claim 1.19 million lives annually worldwide. Lebanon, with a population under 6 million, contends with nearly 1,000 road fatalities each year. Challenges are amplified by population growth, increased household vehicle ownership, deteriorating infrastructure, and the enduring impact of regional conflicts, all further obscured by fragmented data. The dearth of prior research on Lebanese road safety compounds the predicament, impeding informed policy formulation and precise solutions. The thesis unfolds along two main axes: road safety management and driver behaviour. The first axis provides a comprehensive analysis of the current state of road safety management in Lebanon. This analysis delves deeply into the challenges, as well as the historical, institutional, organizational, and financial complexities that shape the current framework for road safety. The thesis evaluates existing policies, enforcement mechanisms, budget allocations, and proposes evidence-based recommendations to improve both road safety and sustainability in Lebanon. This thorough analysis highlights the urgent need for a holistic strategy that covers a wide range of road safety aspects, from strict law enforcement to infrastructure improvements, sustainable funding allocation, and active international collaboration. Recognizing that data is the cornerstone of effective road safety management, the thesis addresses briefly the critical issue of fragmented and incomplete data on road traffic injuries in Lebanon. Focusing on the human factor, the second axis concentrates on driver behaviour, a key element of road safety that has lacked validated tools in the Lebanese context. The thesis advocates for the cross-cultural adaptation of four measurement scales (Traffic Locus of Control, Driver Behaviour Questionnaire, Driving Anger Scale, and Driver Skills Inventory) to understand and mitigate risky driver behaviours. This complex process involves translation, cross-cultural adaptation, rigorous validation, and the involvement of various groups of Lebanese drivers in data collection. Beyond validation, it explores the relationship between driver behaviour and road collisions, with the potential to influence road safety policies and promote good driving practices. This thesis thus serves as a transformative roadmap, aiming to create safer roads, reduce collisions, and improve the quality of life in Lebanon. It is a clarion call to address the urgent need for action and the pursuit of data-driven solutions

Texte intégralAs core processes of the transformation of rainfall into runoff are not fully understood, the concept of hydrologic connectivity has been put forward to explain why some processes occur episodically, in a very discrete short-lived manner, as a response to intermittent atmospheric water input, storm characteristics and soil moisture storage. Even though emerging as a very powerful tool for explaining the growing numbers of nonlinear hydrologic behaviours documented around the world, the hydrologic connectivity concept raises major issues for future research in catchment hydrology in terms of its definition, its measure, its integration into hydrological models and its scaling in the space and the time domains. The aim of this doctoral work is to precise the definition, the measure, the scaling and the prediction of processes underlying hydrologic connectivity while focusing on the following research questions: (1) What methodological framework should guide investigations of hydrologic connectivity?, (2) How to assess hydrologic connectivity from field data?, and (3) To what extent can the ongoing knowledge acquisition on hydrologic connectivity be used to improve success with hydrological modeling? Three study approaches are discriminated, namely: (i) a black box approach that only relies on rainfall and runoff data without examining the internal catchment behaviour; (ii) a grey box approach based on punctual geochemical data illustrating the catchment internal state; and (iii) a white box approach involving exhaustive spatial patterns of surface and subsurface topographic variables and soil moisture. These three approaches are then tested against field data from the Hermine catchment (Lower Laurentians, Quebec). It is possible to classify the Hermine catchment hydrological responses with regards to their magnitude and their timing, the switching from one response type to another depending on antecedent conditions. It is revealed that high discharge values monitored at the catchment outlet are produced by increased contributions from specific runoff sources, thus hinting towards a reinforced hydraulic linkage and an enhanced degree of connectivity between runoff sources and the stream channel. It is established that saturated areas whose spatial extent exceeds 0.85 ha are critical for high runoff generation. Soil moisture spatial patterns in temperate humid forested catchments are shown to have statistical properties that are very different from those encountered in temperate rangelands; hence the necessity of using different spatial connectivity metrics in these contrasted environments. The co-existence of “linear” and “nonlinear” contributing sources is also illustrated in the Hermine catchment. These results suggest that some concepts should be revised for hydrological modeling purposes. The originality of the present thesis is mainly inherited from its prime focus. The pursued research objectives are in accordance with the future trend in catchment hydrology, especially as hydrologists are urged to move from site-specific experiments and results to more easily generalizable concepts that favour the study of emergent catchment properties such as connectivity. Thus, the major contribution of this thesis is the proposal of a unified definition of connectivity, a comprehensive methodological framework, technical tools and operational ideas for the better performance of hydrological models.
