Abstract: Although the Water Framework Directive “is the most substantial and ambitious piece of European environmental legislation to date”, its effective implementation requires a significantly improved understanding of the potential threats from anthropogenic stresses on eco-hydraulic in fluvial and coastal environments, mainly nearby urban centers. This implies being able to predict the pollutant load dispersion in water courses and understand the impact of the flowing conditions in their spread. The monitoring of pollutants concentration in flowing systems is not an easy task and implies the development of reliable methodologies. Seongsoo et al. (2024) ([2]) determined the Fe3O4 concentrations, using color images of the samples. The aim of the present work is to obtain, detailed velocity field and pollutant concentration measurements along space and time in controlled channels with different bottom roughness under the same conditions, to test methodology, to validate numerical models and to use the measurements to develop sub-models that can be implemented in large-scale numerical models.
