Spatial variation of annual and monthly rainfall in Orsang river basin, Gujarat, India

Abstract

Climate change is one of the most discussed issues affecting the environment nowadays. Many researchers have been agreed that the increase in temperature in comparison to the previous century is due to anthropologically related activities, though there are enough historical evidence to support the theory that climate change is a natural phenomenon. This paper reviews the impact of climate change by assessing the trend of annual and monthly rainfall and representing spatial variability over the Orsang river basin in Narmada lower river basin in the state of Gujarat, India. This will be helpful to study the impacts of climate change on hydrology and water resources, and planning & management of water resources, environmental protection, and ecological balance over the orsang river basin, India.
