Physio-climatic controls on vulnerability of watersheds to climate and land use change across the United States.
Masters thesis, Indian Institute of Technology Hyderabad.
Abstract
Understanding a watersheds vulnerability to environmental (climatic and land use)
change is crucial for managing such complex systems and is essential for water re-
sources management. However, obtaining projections of stream ow under changing
conditions across a variety of watersheds is challenging as every step of hydrologi-
cal modeling imparts uncertainty. These ubiquitous uncertainties in projections of
stream ow make it very challenging to provide useful information to water policy
makers and decision makers. In this study, we attempt to identify dominant controls
on watersheds vulnerability to climate and land use change independent of future
projections of climate change. We propose a de nition of vulnerability that can be
used by a diverse range of water system managers and is useful in the presence of
large uncertainties in drivers of environmental change like extreme ow conditions,
as well as others that are relevant from the point of view of instream organisms.
