Current Projects

Flood Inundation through Deep learning approaches

Hydrology / Water Cycle

Rapid and accurate detection of flood inundation from satellite imagery can aid emergency planning and damage assessment. We develop deep learning frameworks to automate flood inundation mapping from remote sensing imagery

Improving streamflow simulations through deep learning approaches

Hydrology / Water Cycle

Incomplete representations of physical processes often lead to structural errors in process-based hydrologic models. Machine learning (ML) algorithms can reduce streamflow modeling errors but do not enforce physical consistency. Therefore, we build hybrid models by integrating process-based hydrologic model outputs with ML algorithm to streamflow simulations across the world
