Geospatial and Environmental Modeling Group
Objective
The Geospatial and Environmental Modeling Group is focused on the research in modeling of varied environmental variables and their applications. It aims to employ cutting-edge technologies in various areas of geosciences and conduct research in both the theoretical and application aspects. The research focuses on following areas:
- Pollutant Forecasting and Monitoring
- WaterResource/Quality Modeling
