Activities of Center for Environmental Research

Potentiality of scientific research and service:

1.Estimate water and air emission by various methods

2. Provide solutions and treatment technologies for mitigating negative impacts of pollutants

3. Design and apply numerical models (one dimension, two dimensions and three dimensions) to simulate and predict diffusion and bio-chemical interaction of pollutants in water and air environment, build inundation risk maps, predict sedimentation in reservoirs…
