The purpose is to describe the characteristics of the selected watersheds, in order to better undertake the following work packages, and to determine the best sampling locations. To reach this objective, the following tasks have been planned:<\/p>\n
T1.\u00a0\u00a0 Literature review <\/em><\/p>\n T2.\u00a0\u00a0 Characterization of the studied watersheds <\/em><\/p>\n T3.\u00a0\u00a0 Inventory of mineralized areas, mining and industrial activities <\/em><\/p>\n T4.\u00a0\u00a0 Modeling of the watersheds<\/em><\/p>\n T5.\u00a0\u00a0 Study of the use of multispectral images from drone flights for estimation of sediment rates and identification of potential sources zones of contaminants<\/em><\/p>\n WP2: Sampling and analysis of sediments and definition of background levels <\/u><\/span> This work package includes the important phases of sampling and analysis of the sediments. Water samples will be also taken in order to study the interaction of both media in different parts of the river. The most important deliverable of this work package is the definition of the background levels of the sediments, obtained after a robust statistical analysis of the analytical results.<\/p>\n T6.\u00a0\u00a0 Sediment sampling in different scenarios in the watersheds <\/em><\/p>\n T7.\u00a0\u00a0 Physico-chemical characterization of samples <\/em><\/p>\n T8.\u00a0\u00a0 Statistical evaluation of analytical data to define geochemical background levels<\/em><\/p>\n <\/div>\n WP3: Assessment of natural\/anthropogenic influences on fluvial and coastal sediments<\/u> <\/u><\/span> After defining the background levels in the previous work package, this WP tries to get the most of the obtained analytical data. First of all, it is intended to find the geochemical genuine characteristics (fingerprint) that define a particular input to the sediments of different nature. This will be useful to characterize the sediments accumulated in the water reservoirs, the interaction between water and sediments, and the historical input to estuarine sediments. Finally, all the information will be available by means of GIS mapping.<\/p>\n T9.\u00a0\u00a0 Definition of geochemical fingerprints<\/em><\/p>\n T10. Characterization of natural\/anthropic influence on solid matter accumulated in reservoirs <\/em><\/p>\n T11. Study of the interaction between river water and sediments<\/em><\/p>\n T12. Evidence of contributions from previous sources in the coastal sediments<\/em><\/p>\n T13. Creation of an open-access GIS mapping including all the gathered information <\/em><\/div>\n WP4: Opportunities, assessment tools and challenges associated with impacted sediments<\/u><\/span> This WP is designed to describe the applied aspects and solutions derived from the previous WP\u2019s. A methodology\u00a0 for the determination of geochemical background levels in sediments of any watershed will be proposed. In addition, the potential valorization of elements of economic interest present in the sediments will be studied. An important deliverable of this WP is the estimation of the risk associated to polluted sediments and related to this goal is the assessment of the affection to aquatic fauna, as physicochemical methods will be complemented by measuring biological diversity of benthic communities and bioaccumulation in predators. Finally, alternatives for reducing the incorporation of harmful elements to the sediments are assessed.<\/p>\n T14.
