Goal and objectives of the project

In recent years, the river basin is known as a hotspot for the degradation of river water quality, which is mainly due to the rapid rise of the population, the intense industrialization and the economic development. Consequently, this study aims to clarifying nutrient transmission (nitrogen) along the river system to the estuaries and coastal areas, assessing coastal nutrient issues while developing modeling tools for environmental management on local and regional scale. Research on applying Material Flow Analysis (MFA) to assess the effects of human activities, especially agricultural activities, to the river basin. This model has the ability to trace the source of pollution, and to visualize and to forecast future contamination with assumptions related to socio-economic development (orientation on agricultural development, industry, population growth forecasts...).
Main results

- Theoretical results:
01 data set of land use status, sources of waste along the Day river
01 set of water quality along the river during dry and rainy season
01 optimal model simulates the flow of nutrients among human activities and the environments in the river basin.
01 report on assessment of reuse and emission of nutrients to the river, major emission sources, using the MFA model
01 report presents environmental (water) quality simulation on river system for the next 50 years
02 publications
- Applied results:
The MFA model will be a useful tool not only in the field of research, but also in the field of state management, to help policy makers easily make decision for water quality management towarding sustainable developement.

 
Novelty and actuality and scientific meaningfulness of the results

A data set on water quality in the Day river in rainy and dry season during the period 2017-2019.
