HAPpy Hour-India Water Model (IWM): Progress in Developing a Transboundary Water Modeling System over South Asia and observational studies
3:00 – 4:00 pm MDT
Dr. Manabendra Saharia from IIT
Dr. Manabendra Saharia is an Assistant Professor in the Department of Civil Engineering at the Indian Institute of Technology (IIT) Delhi and an associate faculty in the Yardi School of Artificial Intelligence. Prior to joining IIT Delhi, Dr. Saharia was a postdoctoral researcher in the hydrology labs of the NASA Goddard Space Flight Center and the National Center for Atmospheric Research (NCAR). He received his PhD in Water Resources Engineering from the University of Oklahoma. At IIT Delhi, his HydroSense lab (https://hydrosense.iitd.ac.in/) focuses on developing physics and data-driven techniques for monitoring and mitigating natural hazards such as floods and landslides.
Effective management of water resources requires reliable estimates of land surface states and fluxes, including water balance components. But most land surface models run in uncoupled mode and are often uncalibrated and hence suffer from large uncertainties at the local scale, hindering their adoption as a tool in real-time decision-making. Such integrated systems are also rare over India where hydrometeorological extremes have
wreaked havoc on the economy and people. The India Water model (IWM) is an integrated national water modeling system being built using the NASA Land Information System Framework (LISF). The talk will cover a suite of tools and studies developed over the past 3 years: a new ensemble precipitation product over India using GMET, a reanalysis product spanning 1981-2022, SAR and deep learning based tool for flood identification, and
associated observational and modeling studies.
