CLIMATE AND LULC CHANGE SCENARIOS TO STUDY ITS IMPACT ON HYDROLOGICAL REGIME 5.2 Aggarwal’, Vaibhav Garg, Prasun K. Gupta, Bhaskar R. Nikam and Praveen K. Thakur Indian Institute of Remote Sensing, Indian Space Research Organisation, Dept. of Space, Govt. of India, 4, Kalidas Road, Dehradun— 248 001, Uttarakhand, India - (spa, vaibhav, prasun, bhaskarnikam, praveen)@iirs.gov.in Commission VIII, WG VIII/4 KEY WORDS: hydrology, climate, modeling, impact analysis, remote sensing, GIS ABSTRACT: Climate change, whether as a natural cycle variability and/or due to anthropogenic reasons, is affecting and likely to further affect the water resources, which is a vital necessity for existence of life form. The predicted intensification of hydrological cycle would change all of its constituents both in time and space domain. This is a long term phenomenon and the necessity is to understand the intensity of the effects on various aspects of water resources by way of scientific studies backed by the available field data. Therefore, in the present study, the impact of climate and land use land cover change on entire India under different assumed plausible hypothetical scenarios has been studied. These scenarios were developed by increasing; temperature by 1, 2 and 3C; rainfall by 5, 10 and 1596; and then the combination of both. To carry out this analysis, variable infiltration capacity (VIC) semi- distributed macroscale hydrological model has been investigated. It was found that slight change in climate may pose huge difference on hydrological cycle and its component. 1. INTRODUCTION Since the beginning of concern over the possible consequences of global warming, it has been widely recognized that changes in the cycling of water between land, sea, and air could have very significant impacts across many sectors of the economy, society, and the environment. The climate change and its impact on hydrological processes are of widespread concern and a great challenge to researchers and policy makers in this changing environment. Moreover, understanding the hydrologic response of very large river basins or entire country offers new challenges and opportunities for hydrologists. The impacts of climate change on hydrology usually are studied by defining scenarios for changes in climatic inputs to a hydrological model in two ways: (i) studies using GCM/RCMs directly to predict impact of climate change scenarios (ii) studies using hydrological models with assumed plausible hypothetical climatic inputs (IPCC, 2001b). The three key issues confronted here are: constructing scenarios that are suitable for hydrological impact assessments; developing and using realistic hydrological models; and understanding better the linkages and feedbacks between climate and hydrological systems. In the present analysis these issues were critically analysed and addressed as discussed below. The rainfall and temperature drives the hydrological cycle, influencing hydrological processes in a direct or indirect way. A large number of studies have been carried out to analyze the trends of variation in these parameters over India/Indian Sub- continent. The projections indicate that the warming would vary from region to region, accompanied by increase and decrease in precipitation (Sahai et al., 2003; Gadgil et al., 2004; Goswami et al., 2006; Ghosh et al., 2009). In addition, there would be change in the variability of climate, and changes in frequency and intensity of some extreme climatic phenomenon. Flood T Corresponding author. magnitude and frequency are likely to increase in most regions, and low flows are likely to decrease in many regions. However, there have been very few studies addressing the issue directly, largely due to difficulties in defining credible scenarios for changes in flood producing climatic events. As it may be observed from these findings, studies using hydrological model with assumed plausible hypothetical climatic inputs would be useful for assessing impacts of climate change on water resources. The evolution of soil-vegetation-atmosphere transfer schemes (SVATS) models, those are applicable to large areas and river basins, has solved the second and third issue to large extent. Therefore, in the present study, the impact of climate and land use land cover change on entire India under different assumed plausible hypothetical scenarios has been studied. 2. STUDY AREA AND ITS CLIMATE India has been known for vast variability in availability of water resources in the country. The main land mass of India is located between 8°4’ N and 37?6' N latitude to 68?7' E and 97°25’ E longitude with the geographical area of 3,287,263 km?. India is endowed with almost all the important topographical features such as high mountains in north, extensive plateaus, wide plains traversed by mighty rivers and ocean in south which influence its climate. That is why; India is a country with extremes of climate. The presence of Himalaya has an important bearing on the climate and water resources of the country. The Himalayan ranges are the primary source of rivers which derive their flow from rainfall, snow and glacier melt. Moreover, Himalayas act as a meteorological barrier due to which the Indian sub- continent experiences tropical monsoon. The temperature in country varies from 47°C at many places in summer to low as - 40°C at few places in Himalayas. The rainfall distribution is also extreme as some places receive negligible rainfall, where,
