1. Introduction In recent years, an increasing attention has been paid to hydropower generation, since it is a renewable, efficient, and reliable source of energy, as well as an asset to reduce the atmospheric concentrations of greenhouse gases resulting from human activities. At the same time, however, hydropower is among the most vulnerable industries to global warming, because water resources are closely linked to climate changes. Indeed, the effects of climate change on water availability

representative of that year's indoor use rate for every month. Both indoor and outdoor per capita water use have decreased with time, reflecting successful water conservation efforts. Outdoor per capita use has decreased at a more rapid rate than indoor per capita use. Outdoor watering, which is currently 45% of the use of the annual water supply, is significantly correlated to monthly or seasonal temperature, precipitation, and PET and is thus the variable most likely to be affected by future climate change

a routing model ( Figure 3 ). It is apparent that a 100% impervious area would generate the maximum flood response from a given catchment. Land cover has a significant impact in peak flow seasonality, volume, and sediment process over a watershed ( García-Ruiz et al. 2008 ). Transformation of natural vegetated land into impervious land increases direct runoff by decreasing infiltration in to the soil. An increase in impervious area as a result of urbanization also affects the time of

groundwater resource for meeting irrigation ( van der Gun 2012 ) and more so of water resource needs of urban/rural water utilities. Furthermore, in certain situations the impact of human activities (e.g., land-use/land-cover changes, urbanization) are found to be much stronger than the climate variability ( Scanlon et al. 2007 ) itself, and hence there is a need to characterize the coupled effects of human activities and climate change on the groundwater system for developing sustainable groundwater

change in rainfall, temperature, and amount of runoff as well as the effects of demographic changes, the status of development projects, and estimates of their likely impact on system resource operation. After setting out the conditions governing the dynamics of the system, the simulation and modeling of surface and groundwater resources are completed, and then a model is used to simulate the dynamics and effects and the interactions between the elements of the system over time. In this study, STELLA
