To meet the requirements of the EU Water Framework Directive, models are useful to predict communities in watercourses based on the abiotic characteristics of their aquatic environment. For that purpose back-propagation artificial neural network algorithms were used to induce predictive models on a dataset of the Zwalm river basin (Flanders, Belgium). This dataset consisted of 120 samples, coll...

In order to determine hydrocarbon contamination of drinking water in the Southern Italian region of Basilicata and to identify its source, we sampled water and subaqueous surface sediments from Lake Pertusillo, a fresh-water, highly dynamic, artificial reservoir located entirely within the largest oil field in Italy (Val d'Agri, Basilicata). Monitoring by the Basilicata Agency for Environmental...

In this paper, we developed a mathematical model for the sedimentation process of small particles in lid-driven cavity flow with an obstacle to transport microplastic rivers. A stationary incompressible Navier-Stokes simulation at moderate Reynolds-numbers provides background field. Spherical are injected into field and their equation motion is solved determine number that sediment on surface o...

Channel beds in estuaries and deltas often exhibit a local depth maximum close to the river mouth. There are two known mechanisms of large-scale (i.e., >10 widths along-channel) channel bed scours: width constriction draw-down during discharge extremes, both creating flow acceleration. Here, we study potential third mechanism: tidal scour. We use 1D-morphodynamic model reproduce dynamics scours...

Background: Health equity is “having fair access to healthcare, utilizing it according to actual needs, paying for it based on financial capacity and finally, having an acceptable level of health”. Health equity is an underlying principle of the universal declaration of human rights. Equitable distribution of hospital beds increases people’s access to healthcare services and as a result, improv...
