About

Dr Negahban-Azar is an Assistant Professor of Water Resources and Environmental Engineering. He leads the Water Security and Sustainability Lab in the Department of Environmental Science and Technology. In his research group, he investigates water reuse and alternative water sources, develop diagnostic decision support systems (DDSS) for water management, and improve watershed scale modeling approaches. Prior to joining the University of Maryland, he was a postdoctoral fellow in the Department of Environmental Science and Engineering at Harvard University. He received his Ph.D. in Civil and Environmental Engineering from Colorado State University, and his M.S. degree in Civil and Environmental Engineering from Tehran University.

Research

Water Reuse and Alternative Water Sources

In water reuse projects there are various limiting factors that need to be considered including water quality concerns, technical feasibility, economic factors, social and environmental factors, and regulatory considerations. We are addressing these challenges by combining observational studies, field and pilot trials, laboratory experiments and mathematical modeling.

 

Diagnostic Decision Support Systems

It is critical to provide stakeholders with the tools they need to make the best decision in water resources management. At the interface of mathematical modeling, resource management and hydrologic science, we develop innovative diagnostic decision tools for planning and managing water systems and evaluate their performance.

 

Watershed Scale Hydrologic Modeling

Watershed-scale hydrologic modeling is essential to water quantity and quality management. By taking a multidisciplinary approach, our research aims at advancing watershed-scale modeling methodologies, and developing and improving the modeling frameworks.

Teaching

ENST 485 - Water Management in Urban Environment

As the population increases and the number of large urban areas keeps growing, managing water in urban areas is becoming more challenging. Water must be supplied for domestic, commercial, and industrial use, as well as irrigation and maintaining and enhancing local environments (e.g., urban streams). In addition, stormwater must be managed to prevent flooding and environmental damage, and used water, which contains organic matter, nutrients, and other constituents that can be extracted and reused, must be collected and managed. In this course we take a systems approach to urban water planning and management. We will explore urban water cycle, urban runoff and drainage characteristics, urban water supply and demand, stormwater collection and treatment, and design of stormwater best management practices.

 

ENST 689P - Water and Development - A Global Challenge

This course offers a multidisciplinary investigation of water systems development and management through real-world case studies. It will develop the concepts and skills needed to design effective policies for developing and managing water resources and their derivative services (e.g., water supply and sanitation, irrigation, flood protection, navigation, hydropower and environmental services).
