Dr. Tapas Karmaker


Assistant Professor


Hydraulics and Water Resources Engineering




Tapas Karmaker is working as an Assistant Professor at Thapar Institute of Engineering & Technology, Patiala. He was appointed to be a part of Civil Engineering faculty in the year 2011. Before joining Thapar Institute of Engineering & Technology, he was working with Tezpur University, a central university (Assam) in the capacity of Assistant Professor for one year. He earned his Doctorate degree from the prestigious Indian Institute of Technology Guwahati, India in the year 2011, and his graduate degree is in Civil Engineering. His Ph.D work involved intensive fieldwork, laboratory scale and numerical modeling of river bank erosion. Other than teaching to undergraduate and postgraduate students, he holds Institute/ departmental level responsibilities. As a faculty in charge of survey laboratory, he is handling the issues related to purchase of the state of the art survey instruments. He was president of the student society "Yatharth" for two years. This society was responsible for organizing the inter-branch activities, workshops, seminars etc. Presently he is the member of the Thapar Institute of Engineering & Technology Student Satellite Programme (THAPSAT).

Description of Research Interests

Tapas Karmaker's research interests include Hydraulic and morphological modeling for predicting the dynamics of rivers, watershed management for simulating runoff. It is found that the rive dynamics can be described as a scale function. River responses globally with decadal changes in the parameters whereas the local problems are short term. The local morphological changes can be modeled with reasonable accuracy by using 2-d depth averaged hydraulic and sediment transport model with sufficient data. Tapas Karmaker is presently working on the effect of the secondary currents and multi-thread flow on formation of river bars.
