Testo completoThe Mediterranean region stands out as a potential ’hotspot’ in climate science which signifies a region where the impacts of climate change are expected to be particularly significant. In Mediterranean region there is intricate interplay between the ocean atmosphere and land, coupled with distinct morphological features. This strong coupling refers to the interactions among the Mediterranean Sea, the atmosphere, and the surrounding land, influencing specific local climate dynamics. In our study, we focused on the Southern part of France located in the northwestern Mediterranean region. Due to these special geographical features and the complex interactions between ocean and atmospheric processes at different spatial and temporal scales, the climate and especially the hydroclimate of the Southern part of France exhibits intricate spatial and temporal characteristics and their variability. There is a lack of understanding of local hydrological processes, which requires a high-resolution comprehensive analysis of all hydrological cycle components in this region. In our work, we will focus on the atmospheric branch of the hydrological cycle in the Gulf of Lion and we will consider precipitation, moisture transport, and surface hydrological processes such as runoff and soil moisture.The aim of this PhD research can be summarized in three main questions addressing the complexities of the hydrological cycle over southern France:1. What are the strengths and weaknesses of various type of datasets in capturing the precipitation variability and its extremes over southern France ?To answer this question, we investigated the accuracy and reliability of all available data sources for this region in representing the actual climatic conditions, providing insights into their applicability for hydrological studies in the Mediterranean region. Results of this analysis are presenting in Chapter 2.2. What are the sources of moisture transport contributing to precipitation and extreme weather events in southern France ?To answer this question, we analyzed the moisture transport in this region. Additionally, we investigated the moisture transport for the conditions of extreme precipitation events. To explores the mechanisms driving of moisture transport we performed clustering analysis of corresponding weather patterns. Results are presenting in Chapter 3.3. How do variability and trends in precipitation impact soil moisture and continental runoff in southern France ?To answer this question, we analyzed the interactions between precipitation patterns and terrestrial components of the hydrological cycle, such as soil moisture and runoff. Reasulate are presenting in Chapter 4.The structure of this thesis is organized as follows: Chapter 1 introduces the data sources utilized in this study, discussing their respective limitations. It also details the methodologies employed to evaluate these datasets and to investigate the sources of moisture affecting this region. Chapter 2 focuses on the examination of precipitation characteristics within the region. It assesses various precipitation datasets to understand their reliability and accuracy in capturing the area’s precipitation dynamics. Chapter 3 is dedicated to analyzing long-term moisture transport patterns. This chapter aims to elucidate the mechanisms behind moisture movement into the region. Chapter 4 delves into the analysis of runoff and soil moisture, exploring their relationship with precipitation. It examines how precipitation influences soil moisture and runoff, contributing to the broader understanding of the regional hydrological cycle

Testo completoAs the water cycle is a driving force of climate, accurate modeling of the various continental hydrological fluxes is a major challenge in climate modeling. These flows are modeled within Land Surface Models (LSM) with a horizontal resolution of about 100 km. At this scale, the representation of continental hydrology is simplified: lateral flows are conceptualized through reservoirs, and their influence on the spatial distribution of soil water content is neglected. Such simplifications introduce biases on the calculation of evapotranspiratory flux and river flow. A consensus is therefore observed within the scientific community on the need to improve the representation of hydrology in LSM. In this context, the objective of this thesis is to develop an upscaling approach of the hydrological processes for LSM, ranging from integrated 3D model to reservoir model. Applied to the Little Washita basin (Oklahoma, USA), this approach is articulated in three steps of dimensionality reduction. First, a 3D simulation is conducted over 20 years using a physically-based integrated code. The 3D model of the basin is then reduced to a 2D equivalent hillslope model. A third step consists in reducing the 2D model to a conceptual reservoir model using simplifying assumptions. Finally, a 1D column simulation is performed using a LSM. A comparison with the conceptual model resulting from the upscaling approach allows us to identify different avenues for the development of LSM hydrology

Testo completoIn the French West Indies (FWI), limited resources supply on island and farming with extensive uses of pesticides have damaged water resources. In environments under intensive banana production, water pollution can be of particular concern, with regards to the use of chlordecone, an insecticide to control the banana weevil. Understanding the hydrological behaviour of a catchment is a challenge in assessing the exposure of the ecosystem to pollutions and in predicting the long-term contamination dynamics. This thesis aimed at developing a model to simulate de surface and underground hydrological processes at the catchment scale on volcanic deposits in a humid tropical area covered by banana plantations in Guadeloupe. First, we developed an original water budget model at the plot scale, adapted to the banana canopy. It takes into account the high rainfall redistribution by banana cover and simulates the effects of modified rainfall intensities and within-plot heterogeneities on the water balance components. The sensitivity analysis showed that rainfall redistribution promotes surface runoff and percolation, in accordance with the field observations, but influences little or only temporarily the average field evapotranspiration and soil moisture. The model calibration tested on experimental data indicated improved runoff production performances compared to a model without rainfall redistribution. Secondly, the Féfé experimental catchment (17.8 ha) was studied with a linked iterative modelling approach (of MHYDAS and MODFLOW) that includes surface and underground hydrological processes. Tested against a year of outlet discharge and water table depth measurements, the linked modelling approach seems appropriate. However, the main limit of this approach was that it does not consider the transfer through the unsaturated zone when simulating the aquifers' recharge. The analysis of the results and of the differences between measured and simulated variables supported the hypothesis, from experimental analyses, that: the surface runoff is mainly Hortonian, groundwater flow is the main contributor to runoff at the catchment outlet. However, there was still uncertainty concerning the main processes during wet periods. Various hypotheses were suggested and should be investigated in future studies. This work represents a first step towards the evaluation of the major flow paths and contamination dynamics of pesticides on volcanic deposits in a humid tropical area covered by banana plantations

Thesis, Toulouse, INPT, 2013. http://www.theses.fr/2013INPT0014/document.
Testo completoThe hydrologic and hydrodynamic processes of the Niger basin are largely influenced by the West African monsoon variabilty. In the last 3 decades these variations have resulted in an increase of extreme events such as floods and droughts. Retrospectively, the climate might be impacted by the evaporation fluxes from the inner Delta flooded region, at least regionally. A better understanding of the Niger basin water cycle is a crucial issue for water resources management but requires observation datasets with a large spatial and temporal coverage. The SWOT satellite mission will provide 2D global maps of water level and slope at an unprecedented resolution (50 to 100 meters). Within the framework of the preparation of the SWOT mission, this thesis aims at proposing a SWOT data assimilation strategy for the improvement of global scale hydrological models. First, the ISBA-TRIP hydrological model from CNRM is evaluated over the Niger basin. This model includes an inundation scheme and simple aquifer reservoir. The model diagnostics are compared to an extensive set of in-situ and satellite observations. According to its relative simple physics, the model is able to simulate in a realistic manner, the continental water dynamics : discharge, water levels, floods, total water storage variations. Sensitivity tests are also performed to determine the most sensitve ISBA-TRIP parameters. Among them, the Manning coefficient has a key role in the flow dynamics but its estimation is difficult and usually based on geomorphologic relationships. The second part of this work consists in setting up a SWOT data assimilation strategy for the optimization of the ISBA-TRIP parameters. Since the SWOT observations are not available yet and also to assess the skills of the assimilation method, the study is carried out in the framework of an Observing System Simulation Experiment (OSSE). The corrected parameter is the Manning coefficient, spatially distributed over the river. The assimilation allows a good improvement of the relative bias of discharge and water level over the river. The Manning coefficient is also globally improved and tends to an optimal value. Moreover, the water storage anomalies and flooded fraction are also better simulated. Finally, the study shows that the method is useful for hydrological forecasting over longer time periods than those of the calibration

"Caractérisation des processus de transferts et d’interactions entre les compartiments hydrologiques, hydrogéologiques et cryosphériques d’un bassin versant andin semi-aride soumis à une forte variabilité climatique (Vallée de l’Elqui – Chili)". Thesis, Montpellier 2, 2014. http://www.theses.fr/2014MON20108/document.
Testo completoThe north Chile is affected by an arid to semi-arid climate, associated with a strong seasonal to inter-annual variability. In this region, while mountainous areas are supporting low areas, the availability of water resources remains limited. In order to improve the water management in these basins, it is necessary to precise how the high areas support the low areas, and to characterize water transfers and interaction processes between the constitutive compartments of the hydrosystem. This work concern the characterization of the hydrodynamic behavior of the Elqui watershed from the headwaters, in the Andes, to the valleys, ranging between 500 and 2000 m.a.s.l.In the headwaters, the interactions processes between cryospheric and hydrologic compartments and their impact on water transfers to the low areas are characterized. The behavior of unglacierized or partially glacierized watershed is also studied. In the low area of the watershed, the study mainly considers groundwater-surface water interactions under semi-arid context and the impact of the climatic variability on these processes. This study is based on more than 40 years of hydro-meteorological data available in the lower zone of the basin, completed by hydrological measurements in the upper zone (> 2000 m.a.s.l.) and chemical (majors and traces elements) and isotopic samples (²D, 18O) over the whole study area realized between 2011 and 2013.This work demonstrated that the conceptual model of the Elqui basin hydrological behavior, generally accepted, was incomplete. In the high area (> 2000 m.a.s.l.), the study of a glacierized watershed show that the function of the cryosphere overpass the water production with some compartments storing water during humid periods and draining their water content during dry periods. This process buffers the temporal variability of precipitations and melting rates in the high area. Physico-chemical analysis, allows to identify some ignored aquifer compartments, as the volcanic and plutonic compartments. The results of this study improve the knowledge about interactions processes between cryospheric, hydrologic and hydrogeologic compartments, which precise the hydrological functioning of the high area. The interpretation of the hydrological behavior of the high altitude area allows to better understand the way that it support the low area, and the way that climate variability may affects it.In the low area, results show that the groundwater-surface water interaction potential is good between alluvial and hydrological compartments, but also between the plutonic and the alluvial compartments. The study of hydro-meteorological and physico-chemical data allowed to characterize the type of exchanges that take place between groundwater and surface water. In some sectors the main process is the recharge of the alluvial compartment by the hydrological compartment, while in other sectors the processes show a seasonal variability with periods of alluvial compartment recharge and periods of hydrological compartment support. The answer of these processes face to climatic and anthropic forcing will constrain the evolution of the availability and quality of the water resources in the Elqui basin. Finally, the results of this study will certainly allow to better anticipate the future modifications of the semi-arid mountainous watershed hydrological functioning

Testo completoIn West Africa, millions of people rely on water resources exposed to the monsoon variability. In this context, the aim of this thesis is to better understand hydrological processes in bedrock areas, and more particularly to estimate the role of lateral redistribution of soil water by the interactions between underground reservoirs, vegetation and atmosphere, using hydrogeological prospection and modeling at field and catena scale. This work is supported by the experimental device implemented in the small Ara catchment in the framework of the AMMA-CATCH observatory. The use of the ParFlow-CLM model allows the simulation of transfers in the saturated and the vadose zone by solving the Richards equation in 3D. The model was forced using observed atmospheric forcing at the surface. We first identify influential parameters for vertical water transfers. Then a spatial characterization of these parameters is carried out. The 1D version of the Parflow-CLM model is assessed using observed data. We show that the model provides relevant times series of the surface energy balance and of soil water distribution as compared to the observations. The impact of the spatial variability of the hydraulic parameters at the field scale (<1 ha) is studied. Finally, the bedrock geometry and the spatial distribution of vegetation are taken into account in the modelling. This allows the identification of horizontal subsurface lateral fluxes, which generate wet and dry patterns, which are related to the spatial distribution of evapotranspiration
