Research Statement


Increasing global mean temperature or global warming has the potential to affect the hydrologic
cycle. In the 21st century, according to the UN Intergovernmental Panel on Climate Change (IPCC),
alterations in the frequency and magnitude of high intensity rainfall events are very likely. Increasing
trend of urbanization across the globe is also noticeable, simultaneously. These changes will have a
great impact on water infrastructure as well as environment in urban areas. One of the impacts may be
the increase in frequency and extent of flooding. India, in the recent years, has witnessed a number of
urban floods that have resulted in huge economic losses, an instance being the flooding of Mumbai in
July, 2005. To prevent catastrophic damages due to floods, it has become increasingly important to
understand the likely changes in extreme rainfall in future, its effect on the urban drainage system,
and the measures that can be taken to prevent or reduce the damage due to floods. Reliable estimation
of future design rainfall intensity accounting for uncertainties due to climate change is an important
research issue. In this context, rainfall intensity-duration-frequency (IDF) relationships are one of the
most extensively used hydrologic tools in planning, design and operation of various drainage related
infrastructures in urban areas.
