Research interests

My research work mainly focus on developing and establishing a robust multiscale parametrization scheme for water and solute transport modeling in meso-to-macro-scale river basins (>103-6 km2). Current work include development of spatially distributed land surface hydrologic models (mHM), innovative methods for providing reliable predictions of hydroclimatic extremes (floods and droughts), prediction in ungauged basins (PUB), assessing and utilizing remote sensing data-sets, geostatistics and optimization algorithms, uncertainty and risk assessment for integrated water resources management, and artificial intelligence techniques for rainfall-runoff modelling.

Projects

2018-present: "eXtreme EuRopean drOughtS: multimodel synthesis of past, present and future events (XEROS)" is a bilateral/joint German (DFG) and Czech (GACR) project focus on improving our understanding and modelling the complex interaction of extremes (floods, droughts, heatwaves), land-surface hydrologic processes and their spatial and temporal variability over a long time scales (past 250-years) across Europe.

2017-2018: "High-resolution Climate Indicators for 1.5 Degree Global Warming (HOKLIM)" is project financed by German Federal Ministry of Education and Research (BMBF) investigating and reporting on the changes in high and low river flows, as well as, soil moisture droughts using the multimodel, high resolution hydrological simulations across EU.

2016-2018: "The End-to-end Demonstrator for improved decision making in the water sector in Europe (EDgE)" is project from the EU based Copernicus Climate Change Service (C3S) on developing a Demonstrator Sectoral Information Service (SIS) based on appropriately tiered dissemination mechanisms of existing and new Sectoral Climate Impacts Indicators (SCIIs).

2014-present: "Inter-Sectoral Impact Model Intercomparison Project", responsible for coordinating the application of the mHM model for the regional water sector.

2014-present: "Hyper-resolution Global Hydrological Modelling" responsible for the application of the mHM model in this project.

2006-present: "Development of the mesocale Hydrologic Model (mHM) and the Multiscale parameter Regionalization scheme (MPR)". The project is part of my research work and is financed by UFZ.

2005-06: "Online flood forecasting using artificial neural network (OFF-ANN)". The project was being done under a DAAD scholarship at Dresden University of Technology, Dresden, Germany for the partial fulfillment of the requirements for the degree of Master of Technology.

2003-04: "Development of manually operated rotary power weeder for weed management in the System of Rice Intensification and other less rice production systems (SRI)".  This Project was financially supported by Andhra Pradesh State Council of Science and Technology (APSCST), Govt. of Andhra Pradesh, Hyderabad, India for the partial fulfillment of the requirements for the degree of Bachelor of Technology.
