Full textAquatic communities (algae, invertebrates, fish) have been used for decades to assess the biological quality of rivers. Practical methods to calculate biotic indices have been designed (e. G. , based on macroinvertebrate diversity indices) to be applied routinely by managers of aquatic environments. These standardized methods did not reflect a repository corresponding to the "reference" state of the communities to be expected under natural conditions. . During the last decade, the European Water Framework Directive 2000/60/EC (WFD) has prompted a large number of works that have led to a redefinition of biomonitoring tools. One of the newer approaches to assessing the ecological quality of rivers within the Framework is the Reference Condition Approach (RCA), where ecological health is defined in terms of similarity to an undisturbed ("reference") state. Although new, RCA-based bioassessment tools are now implemented in continental Europe, these methods are not directly transferable to EU's Overseas Territories, where biogeographic and climatic conditions on the one hand, and lack of knowledge of the fauna on the other hand do not allow to apply current EU standards. We designed a WFD-compliant biomonitoring index adapted to rivers of Guadeloupe (French Lesser Antilles). The development of this index required to deepen our knowledge of the fauna, and then to define a biotypology of rivers. Our results highlight the importance of land use and geomorphology in the definition of three ecological sub-regions (clusters) for benthic invertebrates. Based on this work, it was possible to create a multi-metric index (IBMA-971) to evaluate the ecological quality of rivers. Among 411 metrics (transformed into ecological quality ratio), we selected metrics with a high efficiency of discrimination, poor specificity and high stability under reference conditions. This index consists of 6 metrics derived from taxonomic diversity, richness, abundance and preference for substratum types. From a set of test data, we found that the IBMA-971 was sensitive to a wide range of anthropogenic impacts. This index proved applicable to islands from the same biogeographical region. In addition, an alternative (cost-effective and less time consuming) sampling method for the calculation of the IBMA was tested. Our results demonstrate that artificial substrates allow a quick assessment of ecological quality in Guadeloupe

Full textThe quality of ecosystem services provided by lakes is related to the ecosystem structure and functioning. Protecting water bodies is therefore a global goal that requires a better understanding of their function, a monitoring and a water quality assessment. Explaining spatio-temporal heterogeneities of physico-chemical parameters and phytoplankton has been a recurrent ecological and hydrobiological issue. Understanding the dynamics of these heterogeneities is an essential prerequisite for objectively assessing, protecting and restoring freshwater ecosystems. Moreover, three-dimensional (3D) and taking into account and drivers of these heterogeneities are essential prerequisites for theoretical and applied limnology. Concerning the monitoring, spatio-temporal heterogeneities are responsible of uncertainties on the representativeness of the data versus the whole lake which might be questionable and needs to be verified. In Europe, the Water Framework Directive (WFD) initiated in 2000 defines a framework for managing and protecting water bodies in Europe. The classification of water bodies into ecological status is a key issue for the implementation of that framework. For lakes and reservoirs, the assessment of this status is based on biological, physico-chemical and hydro-morphological indicators. Physico-chemical and phytoplankton indicators are calculated based on four observations at an unique sampling station over the growing season, this evaluation being assessed one year for a six-year management plan. In this context, this thesis focuses on the complexity of lakes functioning and the capability of three-dimensional (3D) models to reproduce their functioning. The contribution of 3D models is presented i) for understanding the functioning of lakes of different sizes, ii) coupled to satellite observations, for studying of the influence of wind forcing and hydrodynamics on phytoplankton abundance and spatial heterogeneities, iii) in the context of the WFD, for assessing uncertainties in the lake ecological status assessment. To do that, two 3D models have been created and analyzed, one for Lake Créteil (42 ha) and another for Lake Geneva (580 km2). Lake Créteil 3D model was validated by using high frequency data recorded at three stations. It reproduces well the complex hydrodynamic functioning of the lake, its thermal structure, the alternation between thermal stratification episodes and mixing events, and internal waves. Lake Geneva 3D model was validated by using monthly and bimonthly data at two stations. It reproduces also properly the hydrodynamic functioning of the lake and the seasonal variability of biological and physico-chemical parameters. Simulation results highlight physical and hydrodynamic mechanisms responsible for the occurrence of seasonal hot-spots in phytoplankton abundance. In the context of the WFD, simulation results show also a strong spatial variability of lake ecological status depending on the timing of the four sampling dates as well as the location of the sampling station. These results were also used to assess to representativeness of sampling stations. The results of this thesis suggest that i) the functioning of lakes of different sizes is complex and physical processes generates spatio-temporal heterogeneities, ii) wind and hydrodynamics influence the abundance and the spatial distribution of phytoplankton et iii) spatio-temporal heterogeneities can bias our evaluation of lake ecological status in the WFD

Although reducing the load of nutrients in aquatic ecosystems is usually looked at through "effects-based" approaches, this is not the context which this paper has chosen to follow. In fact, keeping in line with sustainable development, it seems more relevant to define measures to control pollution which act on cause and effect relations. According to this way of thinking, the methodology proposed by the Water Framework Directive (WFD) to protect aquatic ecosystems presents a number of weaknesses. By the fact that it refers to certain standard economic principles for the environment, the WFD’s economic analysis poses several problems towards acting on the cause of the pollution. Nevertheless, the methodology proposed by the WFD is relevant, as it recommends the combined use of technical measures and of instruments to reduce environmental damage. In accordance with this disposition, an assessment has been made of the effect of technical measures and instruments on the agricultural sector and on the food chain encompassing it, since the food chain is responsible for the majority of diffuse and point emissions of nitrogen and phosphorus in surface waters. The definition of technical measures in terms of efficient use of nutrients (Nutrient Use Efficiency, NUE) in agricultural production has been complemented by a study of economic instruments used in the Common Agricultural Politicy (CAP) to develop a multifunctional type of agriculture. Although the paper deals with the eutrophication of aquatic ecosystems in a general way, it concentrates particularly on the increasing pressures in the Scheldt basin and on their impacts as far as the North Sea coastal zone. Technical measures acting on the causes of diffuse emissions in the agricultural sector and on point emissions in the water treatment plants have been proposed for this basin. These technical measures have been categorised in order of priority according to their environmental effectiveness (thanks to the Sénèque-Riverstrahler et MIRO models) and depending on their direct costs.

Full textData from the assessment of river are big data, with complex relationships. Unsupervised data mining methods can be applied on them and give relevant results for their management, if a close collaboration exists between hydroecologists and computer scientists. The extraction of partially ordered patterns from temporal sequences of physicochemical pressures preceding a biological state has been achieved. These temporal patterns allow to identify a part of the pressures involved or not in a degraded ecological status, to specify the importance of the sequences time-length before a biological assessment, to identify the characteristic pressure categories at a regional scale. To go further, we plan to extend these patterns to hydromorphological pressures
