GEOM Lab (Geomorphology of Mountains and Valleys lab) focuses on understanding the evolving controls of co-seismic, post-seismic, and rainfall-induced landslides in different orogenic settings. We also aim to understand the mechanisms of large landslides and rock avalanches in glaciated environments under accelerated warming, and how they control the fluvial incision in the headwater streams. The geomorphic imprints of catastrophic landslides, their influence on sediment budgets at local and basin-wide scales, and ways to minimize vulnerability and risks are other key areas of our focus. For this, we integrate field, remote sensing, and laboratory analysis; and analyze big data using machine learning models. In our recent project, we aim to develop near-real-time early warning models to mitigate the landslide hazards in the Indian Himalayas by combining WRF model outputs with a comprehensive landslide database.
