Texto completoThe knowledge of the suspended sand concentrations and grain sizes in rivers remains a challenge for river management as these quantities are difficult to measure due to their high spatio-temporal variability. A typical example is the engineered Isère River in France with its high suspended sand concentration over a gravel bed system leading to potential costly troubles for navigation and hydropower generation, depending on reservoir management operations. The aim of this PhD work is to improve and evaluate methods for the hydroacoustic monitoring of suspended sand concentration and grain size applicable to the Isère River. Therefore, measurements with 400 and 1000 kHz Horizontal Acoustic Doppler Current Profilers (HADCPs) were performed in the Isère River at the Grenoble Campus hydrosedimentary station during 27 months. The concentration and grain size of suspended sediments were determined by 31 suspended sediment measurements using the point sampling method. The Sand Discharge Computation method developed by Dramais (2020) was made operational through an open-access toolbox and supplemented with an original uncertainty estimation method. The application of different tools for measuring sand suspension allowed to improve some methodologies and to discuss the limits of some instruments such as an unexplained flux bias using the Delft bottle. Moreover, the masking of sand particles in laser diffraction grain size measurements of silt/sand mixtures was demonstrated and quantified, and further avoided by separating the fine sediments from the sand prior to analysis. Existing single- and dual- frequency hydroacoustic methods introduced by Topping and Wright (2016) were applied and adapted, and provided good estimates of the suspended sand concentration at high temporal resolution, while the hydroacoustic estimations of the grain size do not provide any added value to prior knowledge. The outputs of the hydroacoustic methods are consistent with those of well calibrated empirical rating curves for long-term sand fluxes, but the acoustic methods provide more accurate estimates at the event-scale

Texto completoDo rivers exist by law? The question is not purely rhetorical. Rivers do not have a judicial definition. Referred to as rivers, streams, water resources and running water, they have no other definition. Rivers were dissolved in the traditionnal judicial qualifications handed down by the Civil Code. And so, the Civil Code confers upon the same subject two mutually antagonistic systems. Thus rivers are both, private estate (article 538 of the Civil Code) and part of the public domain (article 714 of the Civil Code). On the basis of the Civil Code, two bodies of text are developped by strata : law oriented towards economic exploitation and another towards sharing. Water management has allowed, along with the policing of rivers, to go beyond this judicial conflict. Environmental law has also pushed aside distinctions which issued from civil law and administrative law. The rapid growth of environmental science has driven the law to take account of Nature's complexity. Science, which fathered this new judicial discipline, has introduced new classing criteria. Thus, water quality, a scientific criteria, has become a judicial criteria in the classing of rivers. A veritable judicial arsenal for the conservation of water has progressively been put in place. However, environmental measures have been shown to insufficiently protect the territorial and ecological integrity of rivers. So, a series of reforms are required to initiate a policy which safeguards the future of rivers and all waterways

Texto completoOver the centuries, many rivers have been regulated by dams to meet various needs such as flood management, hydropower production, irrigation, drinking water supply, etc. Today, in the northern third of the planet, 77% of watercourses are affected by dams and a very large number are under construction or planned in the coming decades. The impacts of dams, particularly those with the largest reservoirs, are now well-known. Their influence, more or less pronounced, can affect floods (flow, frequency, peak and duration), which results in a change of the occurrence of the natural "channel morphing discharge" in the downstream reaches. The result is a modified river morphology and dynamics, with impacts on biological communities and uses. In order to improve/restore aquatic and riparian environments, dam managers are increasingly being asked to generate high flows, known as "flushing flows” or “ecomorphogenic flows”, from their dams.This thesis focuses initially on clarifying the concepts of discharge, water release, and "ecomorphogenic flows”. A new terminology has been proposed that fits into the broader context of “environmental flows” and “ecological flows”. In a second step, previous works and experiments carried out on the Durance River, the Selves River and the Isère River provided elements to build a methodology for implementing ecomorphogenic flow releases as part of adaptive management. This operational methodology is based on a series of successive steps resulting from a preliminary diagnosis. It makes it possible to determine the parameters necessary for designing releases, identifying constraints and defining expected results (target compartments, orders of magnitude of process, etc.) to evaluate the efficiency of the operation. Finally, through the implementation of trigger indicators, it provides evaluation information to decide whether to renew, or improve releases or to replace them with other management actions

Texto completoIn order to make easy the realization of a piscicult management plan of the river Dordogne and to consider the realization of gradings, several searches have been realized. The purpose of this work is to develop an analysis method which makes easy the establishment of a piscicult diagnostic and the development of adapted gestion procedures. The first part states clearly the principal aspects of the piscicult life through of the phenomena's reproduction analysis of requirements'shelters and nourishment. In the second part, directly derived from the conclusions of the first, methods and technics of studies are established. The third part defines the study range : - the Dordogne river and its morphological characteristics and dynamics (descriptives of principal facies meted are derived from this study), - water's physiocochemistry, - the course biology and specially the piscicult peopling study through surrounding utilization by species. The fourth part talks about habitability of the river for the different fishes species. A new indication (indication of total quality of habitat) is suggested and its reliability is analysed and criticized for the river dordogne. The last part forms the application of the suggested analysis method for the putting of gestion plan on a pattern stump of river Dordogne. Finally, the end takes again the principal results presented in this study

Texto completoThe floods of the Saone river are at the origin of the ecological specificity of the val de Saone area, representing both a main factor of the quality of environment but also a significant impediment to riparian communities. While studies of the Saone river are all necessarily influenced by problems of flooding, the main object of our research is more about understanding the dynamics of the hydrosystem during flooding, on several spatial and temporal scales. Functioning is first affected by global geomorphologic processes and major climatic changes, on a scale of 1 000 to 10 000 years. After investigating the Saone river system and changes in its flooding, we observe the geology of the basin and the history of harnessing the river, both of which are bases for the dynamics of the Saone waterlevel rise. The approach, from the scale of the slope basin, shows the importance of these factors in morphological and hydrological matters. The longitudinal heterogeneity of the Saone river waterway is considered and linked to the analysis of a flood sediment load. We next study the downstream area of the river, between Anse and Lyon, which is noted for the amplitude of its hydrological variables. On this stretch of just a few kilometers, we demonstrate how the hydrosystem is affected by phenomena of modifications in channel layout, over a scale of 10 to 100 years, quantified by the diachronic study of this watercourse since 1945-50. This next leads us to examine the Saone river banks and therefor briefer events affecting them. The purpose then, on a scale of two islands, is to study the effects of both floods a human interference on riparian forest, and to observe the influence of new hydrological conditions on the riverside area

Texto completoThe Saulx-Ornain's river basin situated in the limestoned plateaus of eastern Paris basin (Marne-Meuse interfluve) is divided into several lands where discharges conditions and water resources differ. The water table-river exchanges are determined by the morphological and structural context that establishes underground runoffs between adjoining river basins, characteristic of current stream piracy. Campaigns of measures of the low water discharges show spatial heterogenerous water resources, inherent in limestoned nature of substratum. This spatial disparity of hydrological resources increases control problems of old watermills and the Marne to Rhin ship canal. On the Ornain, ship canal taps influence clearly stream flow and limit reconversion of water mills noted on the Saulx. The Saulx and the Ornain show specific problems of river planning in limestoned country

Texto completoThe Moselle River, owing to its geographic localization, is connected to the main European waterways, generating regular establishment of new exotic species. A recent invader (Dikerogammarus villosus, Amphipoda, Crustacea) was used as a model for our study. We defined and analysed its biological and ecological traits, and evidenced a pool of characteristics that could have enhanced D. Villosus invasiveness. Such characteristics are also frequently presented in the literature as shared by invasive Gammaridae. In order to check this hypothesis, and to define whether those traits are common or specific to invaders, a comparison of bio/ecological traits of invasive and non-invasive gammarid species was performed, that revealed the importance of ecological traits, allowing a species to go through the first steps of the invasion process. Moreover, we have shown that invasive gammarids generallly originate from biogeographic areas where this group is highly diversified. Finallly, the study of macroinvertebrate communities in the Moselle River showed an increase of the functional diversity between 1994-2001, with nevertheless a trend to the homogenisation

Texto completoHydrological drought of the last years, especialty the summer 2003, has clealy shown the vulnerability of human activitie exposed to water scarcity. Public authorities who use to monitor hydrological extermes should provide water resource .assessment and forecasting tools. The work relates to low analysis of rivers located in Rhine and Meuse basins. The contrasted physiographic characteristics are observed in order to be compared. The purpose in to propose a single mode fficient for all basins. Methods and modelling are based on recession analysis because during drought period the discharged of rivers essentially comes from groundwater flow. Finally uncertainties related to conceptual aspects have reduced by statistical and probability approaches

Texto completoThe purpose of this thesis is to improve the knowledge of the impacts of human activities on aquatic macroinvertebrate communities of the gartempe river (haute-vienne france), and to draw the conclusions for territory management. The problem is defined from an investigation in the riverside residents, completed by historical and geographical data. Correspondance analysis and the study on invertebrate communities structure lead to a classification of the impacts of 3 small hydroelectric plants, 1 uranium ore treatment plant, 1 gravel open pit, 1 plurification plant, and 2 naturally slow current sections. A distinction is made between pollution, damage, and idication. The respect of safety distances between the installations contributes to limit their impacts and the development of scattered small an middle-sized industry is recommended to fight against country barrenness

Texto completoThe aim of the study is the evolution of alluvial detritism during the holocene in the moyenne durance catchment. Several methods are used : geomorphological and sedimento-stratigraphical analyses : dendrological analyses of subfossil trees well-preserved in holocene deposits; geoarcheological analyses of several sites in alluvial plain ; studies of ancien texts and maps. We observe an aggradation trend since the allerod to the beginning of atlantic. The most important sedimentation rates are during the boreal. Several detritic crisis are detected : at the beginning of younger dryas, at the end of preboreal, during the boreal and at the beginning of atlantic. They succeed with periods of morphological stability corresponding with river forest development (subfossil trees, pinus silvestris). Morphological crisis correspond with climatic crisis. This result accords with other recent paleoclimatical studies. Atlantic correspond with a pedogenic evolution on the slope, a reduction of accumulation rate and incision. This evolution is due to "forest optimum" and regular precipitations. Since atlantic, several crises are detected : during the beginning of subboreal, "la tene", later antiquity, modern times. They are related to climatic degradation and impact of anthropisation. This study point out the importance of climatic changes on the morphological evolution

Texto completoThe Lez karst spring, located in the Mediterranean basin (southern France), supplies with water the metropolitan area of Montpellier (France) since the 19th century. Since 1981, an intense pumping is being performed directly in the main conduit with a maximum exploitation flow rate of about 1,700 l/s. To improve the understanding of groundwater origins and circulation dynamics in this karst system, as well as the impact of three decades of intense water exploitation, groundwater samples have been collected during various hydrologic conditions since March 2006. The springs and wells of the Lez karst system as well as surrounding springs and wells have been monitored for: physicochemical parameters, major and trace elements, Total Organic Carbon (TOC), faecal and total coliforms, 18O, 2H, 13CTDIC and 87Sr/86Sr. During the first recharge events of autumn, high-mineralized waters have been observed at the Lez spring. This singular behaviour was monitored in a fine time-lag. A multivariate statistical analysis revealed the existence of different water-types discharging at the Lez spring. A coupled approach integrating geochemistry and isotopes were applied and provided insight into the different end-members, associated lithologies and the main reactions that control groundwater chemistry. Between the five distinguished water-types, the two more contrasting ones are emphasized: the first one correspond to more geochemically evolved, long residence-time waters, issued from deep layers where evaporite fingerprinting was identified. They are characterized by high mineralization and high concentrations in Cl, Na, Mg, Li, B and Br elements, high Sr/Ca, Mg/Ca and Cl/Br ratios and enriched 13CTDIC and 87Sr/86Sr. Between all the studied springs and wells, this chemical fingerprinting has been uniquely observed for the Lez spring groundwaters. The second water-type corresponds to low mineralized waters with high concentrations in NO3, bacteria and TOC, and represents the flux of rapid infiltration waters. They underline the vulnerability of the system to surface infiltration and anthropogenic contamination through the infiltration of waters by sinkholes and well-developed fracture networks. Hydrograph deconvolutions using multiple tracers were used to estimate the participation of two or three end-members in the various flood-events that occurred between 2008 and 2010. If we use chloride as tracer, the mean estimated participation of the different water types are, as follows: 12% for deep waters; 5% for recent waters and 83% for main aquifer waters. The comparison between present and former studies carried out before the installation of the pumping plant (1973-1974 dataset), indicates historical changes in water hydrogeochemistry, evidencing a decrease of the deep compartment participation to the outflow of the Lez spring. This change in water hydrogeochemistry may be attributed to the intense pumping of the karst system and, in the absence of noticeable climatic changes, traduces the direct consequences of anthropogenic forcing on the overall functioning of the aquifer. The multi-tracers approach combined to hydrodynamics appears as a very efficient tool for characterizing groundwater flows and their origins and seems to be potentially applicable to other similar complex Mediterranean karst systems that were subjected to deep karstification during the Messinian crisis. The features of this crisis seem to play a relevant role on the hydrogeological behaviour of the aquifer and chemical characteristics of waters by the participation of a deep compartment to the outflow of the karst system

Texto completoOnce the river flows into the Massif armoricain, the Loire follows a structural corset interifed from morpho-climatic successions which has been filled integrally by quarternary alluvial deposits. The river path flows between structural ridges along an irregular profile, still persistent even after the strong infill. The current fluvial path would seen increasingly simpler, however the diversity of the fluvial styles in it's length and of ist complexity in the cross-section are considerable. That environment follow the seasons and inter-annual variations of the river flow. The variations of the water-level between flood and low-water level along with the frequency and their respective duration, determine the original "liquidity" of the armorican fluvial valley of the Loire. It is at the source of the evolution of the form and sensibility of the area. A fluvial morphology study through the active band gives the impression of a new landform evolution where man has intervened. The fluvial metamorphosis started at the beginning of the XVIIIth century with the reduction of width of the active band of the river, wich was pratically accomplished by the middle of the last century. However the general alluvionnement which is at the origin of the tressed style ceased later on. The deepening of the river-bed started only at the end of the last century resulting from an acceleration of the pick-up and deposit action, hence modifying the form of the cross-section of the river. The slopes become cleaner and the channel better defined. Inform, with the favorable morpho-climatic conditions,exploitation of the valley intensifies and the need for navigation forces a control of the rivers path and a clearer definition of its banks limits. The will to control the elements of this region, where landscape limits are still poorly defined, encounters today angry reactions. The overflowing of the river, which cannot be easily predicted and are rarely averted does not confine itself anymore to the delimited area which features are set by the environment and the law. Dangers are real because once again the riverside residents are considering exploiting the area. Uncertainties continue to persist. This "liquidity" must nevertheless be controlled

Texto completoThis thesis contributes to understanding the vulnerability of surface water resources of the region Languedoc-Roussillon address climate change. A detailed reconstruction hydroclimatic conditions was first performed over the period 1965-2004 considering the 6 mains rivers of the region. It has shown that the average annual temperature has risen approximately 1. 5°C, reflecting an increasing influence of systems of subtropical high pressure in the spring and summer. Precipitation did not reveal any significant trends, except for winter precipitation that decreased in the north-east of the study area. The average annual flows tended to decrease on all rivers in the region, but significantly only in the Pyrenean basins and downstream river Herault and Orb. The low flows have also become more severe for a large majority of hydrologic stations. The increase of evaporation seems to have played a major role in these evolutions. The simulations from climate models indicate that the temperature should continue to increase in the 21st century, especially in summer, while precipitations would likely decrease. The forcing of a hydrological model calibrated for each river from climate scenarios constructed by the end of the 21st century indicate a significant decline in flows during the period late spring - early autumn with a significant drying of the soil

Texto completoRiparian rights are defined as the sum of the rights belonging to the owner of property bordering on or crossed thereby a river, with regards to this river. Among these rights, one distinguishes the rights of the owner regarding the river's bed and the preferential usage that the riparian owner excercises over the water. There are many restrictions regarding the exercise of riparian rights. There exists, on one hand, restrictions aiming to satisfy private interests, and on the other hand those aiming at the satisfaction of general interests.
