The HydroSIM Laboratory is a part of the Water Resources Engineering Section in the Department of Civil Engineering at Indian Institute of Technology (IIT) Delhi. Our Research Group at HydroSIM Laboratory is interested in better understanding the various hydrological flow and transport processes and providing solutions to associated real-life field problems through numerical and statistical modeling and experimental investigations. Our present research focuses on developing open-source computationally efficient numerical frameworks for surface and subsurface flow and transport phenomena to address the critical problems on groundwater depletion, groundwater contamination, saltwater intrusion in coastal aquifers, and urban flood prediction and management.
