1. Introduction The Three Gorges Dam (TGD) spanning the Yangtze River in Hubei Province, China, is the largest hydroelectric project in the world. The megaproject was built to control Yangtze River floods, generate hydropower, and improve the transportation capacity at the upper reaches of the Yangtze River. Controlling the catastrophic floods downstream is the most important function of TGD since every few decades major flooding of the Yangtze occurs. However, as one of the heaviest manmade

and water supplies in Ireland with statistically downscaled climate data from HadCM3 (see Table 1 for model expansions). Jiang et al. ( Jiang et al. 2007 ) investigated potential impact of human-induced climate change on the water availability in a basin in China using different monthly water balance models. Furthermore, the capability of the models in simulating the impact of hypothetical climate change scenarios were analyzed and compared. Gosain et al. ( Gosain et al. 2011 ) used the Soil and

Four Creeks, it maintains a greater level of direct control over the management of both the water resources and their watersheds, relative to its other surface water sources that are part of the Deer Creek system (described later), including significant watershed protections to maintain high water quality. The high water quality of the Four Creeks not only results in lower capital and operating costs for water treatment but also helps SLC meets federal and state drinking water requirements

-cover condition than precipitation of less intensity. In this regard, the city of Can Tho, Vietnam, is a good example where a combination of runoff increase due to urbanization and climate change has now posed a great challenge for flood management ( Huong and Pathirana 2011 ). Since historical (predam) data are traditionally the sole criterion for dam design, future (postdam) meteorological and hydrological variability due to land-use and land-cover change cannot be considered for design robustness.

Urbanization often modifies the groundwater cycle, and induced changes to the groundwater system may be a sharp decline or rise of groundwater levels, reduced well yields, and deterioration in quality of groundwater ( Tellam et al. 2006 ; Kim et al. 2001 ). Few investigations were made to analyze the groundwater system in urban areas ( Drangert and Cronin 2004 ; Israfilov 2006 ; Ongen and Tinmaz 2006 ; Wolf et al. 2006 ; Srinivasan et al. 2010 ; Rao et al. 2012

is worth pointing out that its reliability is strictly related to the length and quality of available datasets. In particular, unreliable results can be derived when the historical records are either too short (e.g., less than 30 years) or long enough but fragmented by several periods of missing data. Therefore, a scenario-based approach, based on the GCMs predictions, could be considered a fair alternative in case when an impact analysis has to be carried out in a region characterized by daily
