Modeling of Water Quality Evolution with Advanced Hydroinformatic Tool. Study Case: Bega Channel Sector

Abstract

Water quality evolution modeling is very important to predict the changes in surface water quality for water resources and environmental management in the world. Worldwide, in the last decades, hundreds of surface water quality models have been developed. Water quality models based on advanced hydroinformatic tools are an efficient way to simulate and predict the pollutant transport in water courses, lakes and reservoirs, which can contribute to saving the cost of labors and materials for a large number of sampling and chemical experiments to determine the degree of pollution of water bodies. Surface water quality models are useful tools to simulate and predict the levels, distributions, and risks of chemical pollutants in a given water body, in different scenarios of pollution (point source, distributed source and accidentally pollution). The modeling results from these models are very important components of environmental impact assessment and can provide a basis and a technique support for specialists from the water resources and environmental management authorities to make the right decisions. For the case study, we use MIKE11 advanced hydroinformatic tool. MIKE11, part of the DHI software products, is a professional engineering software package for the simulation of flows, water quality and sediment transport in estuaries, rivers, irrigation systems, channels and other water bodies. MIKE11 is a user-friendly, fully dynamic, one-dimensional modeling tool for the detailed analysis, design, management and operation of both simple and complex river and channel systems. The used modules for modeling are Hydrodynamic Module and ECOLab module. The case study was realized on Bega channel sector (city of Timisoara – state border with Serbia), Timis county, Romania.
