Drought preparedness in Kerala: A comprehensive assessment with respect to climate change

Droughts affect almost all the sectors of the society including water resources and agriculture. India is among the most vulnerable drought prone countries. These droughts risks are progressively going to increase with increased temperatures due to climate change. In the project an assessment would be made of climate change impacts of retrospective and future droughts in Kerala. A probabilistic assessment of drought risks due to climate change over Kerala based on multiple Global Circulation Model (GCM) simulations and emission scenarios will be conducted.

Analytical and Experimental Investigation on Frequency Dependent Linear Control Algorithm for Performance Enhancement of Real Life Civil Structures under Random Excitation

This proposal deals with the development of a robust frequency dependent linear optimal adaptive control algorithm aimed at response control of a structural system at a minimum input effort while subjected to an external excitation. Civil structures attract severe force during strong intensity earthquake or strong wind excitations which belong to different frequency ranges.

Linkage of Large Scale Ocean-Atmospheric Phenomena on Hydroclimatic Extremes in India

Inter-annual (El Nino Southern Oscillation (ENSO)), decadal and multidecadal (Pacific Decadal Oscillation (PDO), Atlantic Multidecadal Oscillation (AMO), etc.) ocean atmospheric (OA) oscillations affect different components of the hydrologic cycle and are responsible for extreme hydrologic events such as floods and droughts around the world. Studies have reported that variability in Indian Summer Monsoon (ISM) are linked to ENSO phases.
