Rohi Muthyala focuses on Arctic hydrology and hydrological modeling. The main objective of her dissertation research is to model surface hydrological processes involved in the transport of meltwater over the surface of Greenland Ice Sheet (GrIS). A part of her research is to spatially expand her study area of single catchment into the southwest region of the ice sheet where supraglacial streams play a major role in transportation of melt water on the surface, using commercial satellite imagery and developing a model to simulate the surface hydrology on southwest GrIS.   In 2017, with support from Rutgers Climate Institute, Rohi attended the Polar Boot Camp, a four-day geospatial workshop organized by Polar Geospatial Center (PGC) and the University of Minnesota, focusing on applications of commercial satellite imagery for polar science and operations.  Building on the workshop instruction,  Rohi had a chance to work with the data useful for her dissertation at the PGC  high speed computation labs. After the workshop, she was was able to order the data required for her research from PGC and analyze it. The boot camp training enable Rohi to convert UAV (unmanned aerial vehicle) imagery collected in Greenland ( in 2017 & 2018) into a Digital Elevation Model (DEM) to analyze the supraglacial streams from her study area. She was also able to delineate the catchment using high resolution World View (WV-2) imagery obtained from PGC, in addition to the UAV imagery. Rohi noted, “This not only helped me achieve an objective of my dissertation but also allowed me to meet my peers in the field of polar science.”
