Full textIn order to determine the hydrological impact of future urban development, hydrological modeling is very useful because it allows obtaining hydrological scenarios from urbanization scenarios by considering climate variability. Despite the current diversity of applicable hydrological models to urbanized catchments, those models were generally tested on few catchments, which raises the question of their robustness. The objective of this thesis is to look for a hydrological model structure that is able to reproduce the rainfall-runoff relationship for a large sample of urbanized catchments, located in France and the United States, and characterized by a wide variety of urban sprawl. To do so, we started from an hourly conceptual model structure (GR4H) which was not specifically developed nor tested on highly urbanized catchments. We followed four steps: (1) The collection and preparation of a large sample of data for more than 2000 catchments located in France and the United States. The analysis of the variability of event runoff ratio for 852 US catchments showed the dependence of catchment response not only on mean total impervious area (TIA), but also on antecedent soil moisture conditions regardless of the level of urban sprawl in the catchment; (2) The test of the starting model structure on highly urbanized catchments. This step showed the ability of GR4H parameters to reflect the behavioral specificities of urbanized catchments; (3) The regionalization of GR4H parameters in order to relate them to the fraction of urban cover in the catchment. The obtained regression relationships performed well but showed weak sensitivity to change in the fraction of urban cover, which impeded their use for scenario prediction; (4) The step-by-step modification of the GR4H model structure by including excess rainfall on impervious surfaces, and by varying the partitioning between quick flow and slow flow depending on each catchment. The evaluation of these modifications on 273 urbanized catchments indicated an improvement in reproducing the observed flows in comparison to the original structure, especially during dry and flooding periods. The added parameters showed a strong dependence on the mean total impervious area. This thesis work illustrates a constructive modeling approach by which we have succeeded in both (1) improving the representation of urbanization within the model and (2) obtaining better simulation of catchment response. An effort of regionalizing the new model structure using measures of urban landscape fragmentation will allow to better estimate the impact of different urban planning schemes on the hydrological behavior at the catchment scale

Full textThe water cycle encompasses the main processes related to mass fluxes that influence the atmosphere and climate variability. More specifically, continental hydrology refers to the water transfer occurring at the land surface and sub-surface. Modelling is one of the main methods used for the representation of these processes at regional to global scales. The land surface model system used in this thesis is composed of the ISBA land surface model coupled to the river routing model TRIP that combines the CNRM’s latest developments for use in stand-alone hydrological applications or coupled to a climate model. This PhD is focused on the development and evaluation of lake mass-balance dynamics and water level diagnostics using a new non-calibrated model called MLake which has been incorporated into the 1/12° version of the CTRIP model. Simulated river flows forced by high resolution hydrometeorological forcings are evaluated for the Rhone river basin against in situ observations coming from three river gauges over the period 1960-2016. Results reveal the positive contribution of MLake in simulating Rhone discharge and in representing the lake buffer effects on peak discharge. Moreover, the evaluation of the simulated and observed water level variations show the ability of MLake to reproduce the natural seasonal and interannual cycles. Based on the same framework, a final evaluation was conducted in order to assess the value of the non-calibrated MLake model for global hydrological applications. The results confirmed the capability of the model to simulate realistic river discharges worldwide. At 45% of the river gauge stations, which are mostly located within regions of high lake density, the new model resulted in improved simulated river discharge. The results also highlighted the strong effect of anthropization on the alterations of river dynamics, and the need for a global representation of human-impacted flows in the model. This study has lead to several future perspectives, such as the incorporation of a parametrization of lake hypsometry for use at global scale. The implementation of such developments will improve the representation of vertical water dynamics and facilitate both the coupling of MLake within the CNRM earth system model framework and the future spatial mission SWOT for improved future global hydrological and water resource projections

Full textMany hydrologic models were developed in the last few decades. They should be capable of simulating all of the catchments but, in practice, their performance is dependent on the geology and climate, so no model structure is suitable for all modeling tasks. This doctoral thesis aims at proposing a model selection method, from a grand pool of candidates, which accounts for the identification of a pool of successful models in diversified climates conditions and the selection of appropriate models for the catchment climatic conditions (arid, humid, and continental) and modeling objectives (high, medium and low flows). It is based on 1446 models constructed using the Ensemble Multistructure Framework (EMF) and 100 climatically diversified American catchments. The focus of this study is to value flexible modeling approaches to identify successful models for a variety of climates. The model selection is first based on the individual performance of the 1446 models, comparing them to a reference model (GR4J). A pool of 80 diversified models is then identified for further investigation. To evaluate the impact of climate and metric on model performance, the 80 preselected models are evaluated on the three types of climates and three modeling objectives. At the end, four new lumped conceptual hydrologic models are tailored for specific climate and flow conditions. Hydrological modeling remains imperfect due to a large number of uncertainties, particularly related to the description of rainfall-flow transformation by hydrological model structures. The multimodel approach is an alternative solution, because the combination of existing models gives better results than individual ones. The diversity of model structures touches one of the first principles of the operation of a multimodel is the compensation of the errors to improve the performances. The 80 preselected models and the Backward Greedy Selection (BGS) algorithm are then used to select the models set to combine. Tests are performed on six optimizations (MCRPS, KGEsqrt, Mlogs, NRD, PIT and RDmse). Results show that, the optimization by the MCRPS is most interesting when compare to other criterions.

Full textUne méthode automatisée de découpage du bassin intermédiaire en sous-bassins a d'abord été élaborée afin de faciliter la construction du modèle hydrologique sur les 50 tronçons de rivière. Des tests de sensibilité ont été menés sur le nombre de sous-bassins, la nature uniforme ou distribuée des entrées de pluie et des paramètres du modèle hydrologique. Une configuration à 4 sous-bassins présentant des pluies et des paramètres uniformes s'est avérée la plus performante sur l'ensemble de l'échantillon.
Enfin, une méthode alternative de calcul des apports latéraux a été proposée utilisant une transposition du débit mesuré à l'amont et une combinaison avec le modèle hydrologique.
