Biography

Dr. Dharmappa (Dharma) Hagare is a Senior Lecturer in Environmental, Sustainability and Risk Engineering in the School of Engineering. Dharma has over 15 years of academic and 5 years of industrial experience in a wide variety of areas of Civil and Environmental Engineering. Dharma has published over 100 journal, conference and seminar papers, technical reports and book chapters. Also, received an award for best technical paper.

Dharma developed several e-resources to teach and train students and professionals in Environmental Engineering. He lead a multi-disciplinary team to develop “H2O – Multimedia Package” for teaching undergraduate and postgraduate students in water and wastewater engineering. Also, developed a computer program "WATOPT" for optimal design and simulation of water treatment plants.

Dharma successfully managed several projects related to design, construction and operation of water and wastewater treatment plants. Also, Dharma successfully completed several Risk Assessment and Management projects including Environmental Management Plans for Mines and use of Recycled Water.

Computer Programs Developed

H2O - Multimedia package - for teaching water pollution control processes to environmental engineers. Developed an interactive multimedia software package "H2O" to illustrate the operation and design of water pollution control processes. This package is currently being used for teaching Civil and Environmental Engineering students. This is an exhaustive package comprising of 7 modules.
WATOPT - A program for simulation, design and optimization of water treatment systems comprising rapid mixing, flocculation, sedimentation, granular filtration, microfiltration, ultrafiltration and sludge treatment processes.
