| Session Description | Extreme hydrologic events, such as heavy rainfall, floods and droughts, though occur rarely, have adverse impact on water resources management. Recent revelation of rapid climate change further aggravates these issues. Spatio-temporal changes in most of the hydrologic variables are in active research focus. IPCC Special Report on Managing the Risk of Extreme Events and Disasters to Advance Climate Change Adaptation, also known as the IPCC SREX, clearly states that extreme events are primarily linked to the human induced climate change (IPCC, 2012). The challenges in estimating and understanding the extreme events in 21st century through future projections further add up the difficulty. The incorporation of future projections will shoot up the uncertainties (through model, internal variability, scenario and downscaling) in studies related to impacts of climate change. Consideration of climate change in projecting the non stationary extreme events and reducing the uncertainties for decision and policy making is one of the largest knowledge gaps in climate change studies. Extreme event modelling studies need to consider the changing climate to develop proper adaptation and mitigation strategies. In this special edition, we propose to address the following areas (but not limited to): i. Surface and Ground water management under climate change ii. Variations in extreme hydrological events and possible attributing factors iii. Present methodologies adopted, limitations and advances iv. Stationarity/ Non-stationarity factors v. Case studies on climate change impact assessment at local/ basin/ regional scales vi. Flood and Drought analyses vii. Streamflow assessment and Reservoir operation viii. Future climate and hydrology ix. Change in spatio-temporal pattern of precipitation x. Adaptation and Mitigation strategies xi. Policy making xii. Remote sensing applications |
