The issue of global climate change has begun to play an increasing role in scientific and policy debates over effective water resource management. In recent years, the evidence that global climate change will have significant effects on water resources in different parts of world has continued to accumulate. Urban areas, though chiefly responsible for climate change, will become the hub of aftermaths of this issue. In growing body of literature, it can easily be observed that most of the studies focus on a single study area; methodologies are case-specific and are not flexible enough to be adaptable to other geographical conditions. It is mainly due to the limited knowledge of local effects of climate change and ultimately the studies are conducted at large scale with generalized approach. The target of this paper is to develop a methodological framework which can help to assess water resources existing in urban settings of different climatic regions. General circulation model (GCM) with the integration of climatic classification model has been proposed where all the indicators of GCM should be included, as they sheer in real world. Water budgeting concept has been incorporated so that more specific results can be sought out of the GCM. This study proposes to focus on a large set of objectives for urban water resource management; from precipitation to urban surface runoff; from evapotranspiration to pollution; everything from improvements in downscaling of general circulation models to understanding how reservoir operations might be adapted to different climatic conditions. It is recommended to explore the vulnerability of both structural and non-structural water systems to plausible future climate changes, not just past climatic variability. It is also been proposed that governments at all levels should re-evaluate legal, technical, and economic approaches for managing urban water resources in the facet climate change.
