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 intensa • El aumento del nivel del mar = inundación de la infraestructura de agua Observed Air Temperature Change (1991-2012 vs 1901-1960) COOLER ENFRIADOR HOTTER Observado Cambio De Temperature de Aire (1991-2012 vs 1901-1960) Increases in Air Temp Cause Increases in Water Temp In Streams, Rivers, and Lakes El aumento de la temperatura del aire I will arise and go now, for Aumenta Causa en la temperatura always del night and day agua I hear water ríos lapping with En lake los arroyos, y lagos low sounds by the shore; While I stand on the roadway, or on the pavements gray, I hear it in the deep heart’s core William Butler Yeats from The Lake Isle of Innisfree Ernest Litichius “Falls of the Kaaterskill” 1857 Many temperate lakes display temperature stratification during summer Muchos templado lagos estratificación de la temperatura pantalla durante el verano Warm más cálido Cooler Enfriador Length of season in which differences in lake temperatures with depth cause stratification (separate density layers) is increasing in many lakes.

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. Adapting to flood risk under climate change Robert L. Wilby r.l.wilby@lboro.ac.uk Loughborough University, UK Rod Keenan University of Melbourne, Australia 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.
