3D Modeling for environmental and public health risk assessment of the Miljacka river

BackgroundWater quality is a critical component of environmental and public health, as polluted water bodies can lead to serious health outcomes. The Miljacka river, flowing through Sarajevo, has been significantly impacted by industrial and urban wastewater discharges.ObjectiveThis study aims to develop a 3D digital model of the Miljacka river, built on topographic and satellite data, to support improved pollution assessment and inform water quality management strategies.MethodA 3D model of the river was created using integrated hydrological, topographic and satellite data. Initial 2D schematics were developed in AutoCAD and visualizations were produced in SketchUp, Revit and Twinmotion to simulate river flow dynamics and pollutant dispersion. Areas of interest were identified to assess the spatial distribution of contaminants.ResultsThe model enabled the visualization of pollutant movement and the identification of potentially high-risk zones along the river's course. Analysis of the available data suggests possible impacts of pollution on public health, particularly in relation to chemical contaminants and microbial loads, although further studies are needed for a more precise assessment of health risks.ConclusionThis research highlights the importance of integrating advanced digital technologies in environmental health assessment.
