Freshwater and Climate Change
Agua y Cambio Climático
“Water is the most
significant resource that
is currently threatened
by climate change.
Water not only sustains
our environment, but it
also impacts the lives of
individuals and the
economic security of
nations.”
IPCC
Según el panel
intergubernamental sobre
el cambio climático, el
agua es el recurso más
importante que se está
amenazada por el cambio
climático. El agua no sólo
sustenta nuestro medio
ambiente, sino que
también impacta en la
vida de las personas y la
seguridad económica de
las naciones.
PROJECTED CLIMATE CHANGES
Cambios climáticos proyectados
• Increases in air temp , thus
warmer waters
• Rainfall amounts: decline in
some areas and increase in
others
– snow prop. decreases
• Rainfall and storms are
expected to be more intense
• Rising sea level = inundation
of water infrastructure
– water treatment facilities,
and degrade coastal
groundwater resources
• El aumento de la
temperatura del aire, las
aguas más cálidas de este
modo
• Las cantidades de lluvia:
disminución en algunas
zonas y el aumento de otros
• Se espera que las lluvias y
las tormentas a ser más

• El aumento del nivel del

We distinguish between
the enabling environment for adaptation and
specific implementing measures to manage
flood risk. Enabling includes routine
monitoring, flood forecasting, data exchange,
institutional reform, bridging organizations,
contingency planning for disasters, insurance
and legal incentives to reduce vulnerability. All
such activities are ‘low regret’ in that they
yield benefits regardless of the climate
scenario but are not cost-free.

Adaptation and Institutional
Responses (NCA)
• In most U.S. regions, water resources managers and
planners will encounter new risks, vulnerabilities, and
opportunities that may not be properly managed
within existing practices.
• Increasing resilience and enhancing adaptive capacity
provide opportunities to strengthen water resources
management and plan for climate change impacts.
Many institutional, scientific, economic, and political
barriers present challenges to implementing adaptive
strategies.
Power plant cooling is a critical national water
use, because nearly 90% of the U.S. electrical
energy is produced by thermoelectric power
plants
Interagency 2011 report
Ten Indicators of a Warming World
ESPANOL
NYCDEP has a very complex modeling environment. It currently does analysis using the Variable
Source Loading Function (VSLF) or the SWAT watershed models. These can in turn provide inputs t
one of two reservoir models: a one-dimensional reservoir eutrophication model; or a twodimensional reservoir turbidity transport model (CEQual W2). The OASIS reservoir system operatio
model requires measured or simulated water inputs to the reservoirs and simulates the storage an
transfer of water between the 19 reservoirs comprising the NYC water supply system. The watersh
models, take daily temperature and precipitation data to generate streamflow and
evapotranspiration, as well as a number of water quality parameters. Outputs of the watershed
models can be used to drive both the OASIS system model and reservoir water quality models. A
knowledge of reservoir operations is an important determinate of reservoir water quality, and a
needed input to the reservoir models. For future climate simulations, where historical operations a
not known, OASIS simulation are needed to specify reservoir operation scenarios associated with a
given climate scenario. All of the above models were in use at NYCDEP to evaluate the impacts of
changes in watershed management, land-use, and reservoir operation policies. This integrated
modeling system was easily adapted for evaluation of the effects of climate change, once credible
future scenarios of the meteorological variables needed to drive the models were available.
