    Current European water law inspires research, within which it is necessary to investigate numerous phenomena, with the aim to place responsible authorities in the conditions for the correct application of the norm. The attention is addressed mainly to the attainment of good water quality status, according to Water Framework Directive (WFD). This paper briefly presents a methodology used for implementation of watershed approach, with an aim of defining water quality in the lake’s immissary as a result of all different pollution-generating activities within the watershed. This paper describes therefore research lines of monitoring and modelling efforts to characterize nutrient loads in watershed scale. Following this integrated approach, it has been possible to identify satisfactory solutions to develop watershed project

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
