Texto completoUne méthode de désagrégation statistique, basée sur le concept de type de temps, est développée et mise en œuvre afin de régionaliser un ensemble de scénarios climatiques pour forcer un modèle hydro-météorologique. Des impacts sévères sont visibles dès le milieu du 21ème siècle, avec notamment une forte diminution des débits moyens en été et automne, et une large augmentation du nombre de jours d'étiage.
D'autres méthodes de désagrégation sont utilisées afin de tester la sensibilité des résultats
au choix de la méthode: celle-ci s'avère limitée. La principale source d'incertitude
réside en fait dans le choix du modèle climatique. Nous essayons pour finir de mieux comprendre les raisons physiques de cette dispersion des scénarios climatiques sur l'Europe.

Texto completoAs most of Europe, France might undergo severe climate changes during the 21st century. In this thesis we study the impacts of these changes on the hydrological cycle, at the scale of the French river basins. A statistical downscaling method, based on the concept on weather types is built and applied to regionalize an ensemble of climate scenarios in order to force an hydro-meteorological model. Severe impacts occur as soon as the middle of the 21st century, characterized by a strong decrease of mean river flows and a great increase in the occurrence of low-flow. Other downscaling methods are used in order to test the sensivity of the results to the choice of the method: this sensivity is limited. Actually, the main source of uncertainty lies in the choice of the climate model. To finish, we try to better understand the reasons for the spread of the climate change scenarios over Europe

Texto completoAgriculture requires water to meet the biological needs of crops. When the water supplied to the soil by precipitation is not sufficient, additional water can be taken out from bodies of water and supplied to crops : this is irrigation. With the intensification of the risk of drought, agricultural territories are particularly affected by climate change. It is therefore necessary today to develop and evaluate adaptation strategies. To do this, we must take into account the evolution of irrigation water demand in future hydrological projections. Given the multiplicity of challenges related to climate change adaptation and agriculture, it is also important to implement integrated approaches and taking into account uncertainties. Furthermore, it is necessary to formulate concrete strategies, which must be defined at a sufficiently local scale. Explicit modeling of agro-hydrosystems already exists. However, these models are often complex, and require a large amount of data and simulate numerous processes. In contrast, there are conceptual hydrological models that are parsimonious, efficient, and operational but usually do not explicitly account for uses. The objective of this thesis has therefore focused on developing a framework of intermediate complexity. Firstly, a model was developed, integrating i) the modeling of hydrology using the conceptual hydrological semi-distributed daily GR5J model, ii) the modeling of irrigation water withdrawals using the daily agronomic model CropWat, and iii) modeling of storage structures and their management, such as reservoirs and dams. This modeling was first implemented on the downstream Aveyron watershed. The irrigation simulations obtained were compared with simulations from the MAELIA platform, an explicit agro-hydrological integrated model that has been the subject of numerous developments and surveys in this area. The model was also implemented in the Seille catchment, a tributary of the Moselle, on which there is no irrigation but which is currently experiencing new difficulties related to droughts. In a second phase, the developed model was applied in a prospective exercise that examined different scenarios for local agricultural and water management evolution in the Seille watershed. Interviews with local water and agriculture stakeholders were carried out to produce three plausible evolution scenarios for the Seille watershed by 2050, implemented in the model. The work carried out in this thesis confirmed the interest and necessity of integrating irrigation water withdrawals into conceptual hydrological modeling to evaluate local agricultural scenarios in the context of climate change. Thus, our work highlightedthe impacts of human influences on watershed hydrology, and the sensitivity of the model to different agricultural and water management scenarios. Our research also emphasized the need to use various indicators, both hydrological and related to water demand satisfaction, to evaluate the impacts of climate change. Nevertheless, this study revealed that in the studied area (the Seille catchment), considering future scenarios, the predominance of uncertainty related to climate projections on future low-flow periods outweighed the uncertainty linked to changes in irrigation water demand. Some projections thus lead to significant difficulties for non-irrigated spring crops, in particular maize. Finally, a parsimonious and easily reusable modeling framework was developed, which can be applied in other regions

Texto completoThe impact of global change on regional climates and in turn on water resources is expected to be especially pronounced in mountainous areas. Future hydrological scenarios required for impact studies are usually simulated by forcing an hydrological impact model (HM) with high-resolution meteorological scenarios, obtained from statistical downscaling models (SDMs) forced by climate models (GCMs or RCMs) outputs. These SDMs are expected to fill the gap between the poor resolution and the bias of climate models scenarios and the requirements of impact models. Although a number of projections are currently performed worldwide, the relevance of the simulation chain GCM/SDM/MH is rarely discussed. We present here an evaluation framework to illustrate the possibilities and/or the difficulties to transfer in time these algorithms. We next illustrate the uncertainties in future meteorological and hydrological projections that can result from this imperfect transferability. Simulations and evaluations are performed for the Upper Durance Basin (3580 km2). The hydrological model SIM from Météo-France is adapted for the alpine context. We consider several configurations of 3 SDMs from CERFACS, LTHE and EDF, based on different atmospheric predictors. 12 climatic runs from the ENSEMBLES european project provide the large scale fields for the 1860-2100 period. In this context, the SDMs and GCMs related uncertainties are of the same order of magnitude

Texto completoThe assessment of the impact of climate change often requires to set up long chains of modeling, from the model to estimate the future concentration of greenhouse gases to the impact model. Throughout the modeling chain, sources of uncertainty accumulate making the exploitation of results for the development of adaptation strategies difficult. It is proposed here to assess impacts of climate change on the hydrological cycle over France and associated uncertainties. The contribution of each sources of uncertainty is not addressed, mainly that associated with greenhouse gases emission scenario, climate models and internal variability. In the context of impacts of climate change on the hydrological cycle over France, it is possible to ask what is the contribution of each sources of uncertainty to the total uncertainty associated with mean changes. Is it possible to reduce, and if so how, the contribution of one source or another ? We propose in this work an approach to assess the transferability in the future climate of a statistical method to downscale climate simulations. The transferability assumption is one the main sources of uncertainty in statistical downscaling method. The assessment suggested here relies on the use of regional climate models, in a perfect model framework, and shows that some predictors are useful to ensure the transferability of the downscaling method in the future climate. This framework, proposed for a statistical downscaling method, is also applicable to bias correction methods in regional climate models. Recent atmospheric reanalyses of the 20th century are downscaled with the method developed in this work, associated with observations of temperature and precipitation. The hydrological cycle over France is characterized with these reconstructions. We show that the multi-decadal variability of observed streamflows during the 20th century is generalized to the whole country and is partly due to atmospheric variability. This multi-decadal variability of streamflows is generally weaker in hydrological simulations done with historical simulations from climate models. The climate projections have been downscaled with the method developed in this work. The temperature on the country, on average over climate models, could increased by 3,5°C in winter and 6,5°C in summer in the course of this century. Precipitations will decrease all over the country in summer, nearly by half on southern part of France for the most severe scenario. In winter, precipitations will increase in the northern part of the country and will decrease slightly in the southern part. In the next few decades, the decrease in precipitation is important in summer, and changes are less pronounced for other seasons. Results of hydrological projections done with one hydrological model and an ensemble of climate models are presented for the coming decades and for the end of the century. On the Seine river, results slightly differ in winter from those presented in previous studies. Here, precipitations and streamflow increase in winter and decrease in summer on that river basin. Elsewhere in France, results are consistent with previous studies, namely an increase in evapotranspiration, a decrease in streamflow and much drier soil. The uncertainty due to both climate models and internal variability on relative changes in streamflows always increase during the 21st century, to over 20% in winter for the most severe scenario. In the coming decades, the uncertainty due to internal variability only on streamflow changes is as strong as the uncertainty due to both climate models and internal variability. In the coming decades, annual streamflow changes of the Loire, Garonne and Rhône rivers are stronger than the maximum changes observed during the 20th century

Texto completoTypical hydrological models do not impose energy conservation at the surface. Therefore, under higher temperatures they may overestimate evapotranspiration. Physical land surface model CLASS is paired to Muskingum based routing model RAPID in order to create a functional hydrological model under global warming context. CLASS-RAPID is set up on the Haut-Montmorency watershed (47.4°N, 71.1°W). The model is calibrated and validated with the ERA5 reanalysis and the flowrates observations from the Direction d’expertise hydrique du Québec. Climate projections from CanESM2, CNR-CM5, GFDL-ESM2M and MPI-ESM and climate scenarios RCP 4.5 and RCP 8.5 are given as entries to CLASS-RAPID in order to simulate flowrates for 2041 to 2070. Climate projections from the same models and for the benchmark period of 1981 to 2005 are used by CLASS-RAPID in order to obtain hydrological simulations that can be compared to the flowrates of 2041 to 2070. CLASS-RAPID has a Nash-Sutcliffe coefficient of NSE = 0, 66. The model tends to replicate hydrological events sequence correctly but underestimate flood peaks. CLASS-RAPID simulations under climate changes conditions foresee that spring floods will tend to happen sooner in the years for 2041 to 2070 when compared to the benchmark period. For the four climate models, climate changes simulations foresee reductions of summer flowrates of 40% for climate scenario RCP 4.5 and of 50% for climate scenario RCP 8.5. For the same climate scenarios, the Atlas hydroclimatique du Québec foresees a reduction of the flowrates of respectively 37% and 45%.

Texto completoThe southern Mediterranean region, at the interface between arid and temperate climates, is highly vulnerable to climate change and water availability. The moroccan Middle-Atlas mountains contains several natural lakes regarded as sentinels of hydro-climatic changes, provided that their hydrological functioning is clearly understood. This thesis work was focused on the study of the hydrogeochemical and hydro-isotopic functioning of Azigza lake based on a monthly monitoring (October 2012–October 2016). The physicochemical and chemical parameters (major elements), allowed to propose the mechanisms associated with the mineralization of lake waters and the characterization of groundwater inflows from watershed into the lake. The waters of the Azigza lacustrine system fall under the calcium-magnesium-bicarbonate category. The lake is hot monomictic type. The waters show a seasonal response to climatic variations.The isotopic data allow to specify the origin of waters, the recharge altitude, the residence time of waters. The daily data of water level highlights the fast response of the lake to precipitation. During the whole observation period, the lake level decreased by about 4 meters. This approach was used to simulate the variations of the lake level over the observation period and to quantify the contributions of the groundwater flows. This approach was used to simulate the variations of the lake level over the observation period and to quantify the contributions of the groundwater flows. The hydrological model was then tested to reconstruct historical lake level variations. Finally, the possible use of the model to predict future lake level is discussed
