The research of my group focuses on the following aspects of non-structural approaches for flood management, specifically for data scarce regions:

(i) Flood inundation modeling, hazard and risk assessment: Methodologies are being developed to address data scarcity issues in developing countries like lack of high resolution DEM, cross-section data, and sufficient and accurate calibration and validation data sets. Also, methodology is being developed for optimal allocation of rice varieties for floodplains by maximizing net benefits and considering the flood risk. These studies are being carried out using MIKE models in different river basins like Mahanadi in Odisha, Elbe in Germany and Bharathapuzha in Kerala etc.

(ii) Flood forecasting: Poor raingauge network as well as unavailability of rainfall data in real-time hinders the accuracy of flood forecasting at different lead times. We are focusing on the use of real-time satellite-based rainfall products for flood forecasting as they are now increasingly becoming available for the data-scarce regions. Their integration with the data-driven models (like neural networks with the use of wavelets) as well as physically based models (like the MIKE models) could be effectively used for real-time flood forecasting. The idea is to improve the accuracy of flood forecasts at higher lead times.

(iii) Impact of climate change on flood risk: The idea is to analyze the impact of projected climate change on flood hazard/risk in a river basin, and to develop management scenarios to minimize the impact of climate change on flood hazard/risk in the river basin.

(iv) Flood estimation: Regional flood formulae are being developed by integrating L-moments based approach with soft computing techniques for small size gauged and ungauged catchments of India covering different hydro-meteorological regions. The focus is on estimation of floods for small catchments where adequate runoff data are generally not available.
