Detection of Changes in the Annual Rainfall over theTapi Basin of Central-Western India
Authors(2) :-Rajendra Gunjal, Pramodkumar S. Hire It is widely accepted that various elements of climate, especially rainfall, is extremely sensitive to climate change phenomena and it is reflected through the variability in its amount and intensity. In this paper an attempt has been made been made to evaluate the long-term changes/trends in the annual rainfall over the Tapi Basin from Central-Western India by using the test of Mann-Kendall. The rainfall data were procured from India Meteorological Department (IMD) for fifty six raingaugestations located at the tahsilheadquartersin the basinfor the 20thcentury. It is obvious that the scrutiny of various stations in the basin will underline visible long-term changes/trends in the rainfall at few stations. However, summarizing the rainfall trends obtained at various stations in the basin, it is evident that the low rainfall stations in the basin shows a significant increasing rainfall trend. The stations having rainfall close to the average rainfall of the basin does not present increasing or decreasing rainfall trend. Most importantly, the Tapi Basin, as a whole, does not show any significant rainfall trend over the period of a century. Since, the rainfall over the Tapi Basin not had undergone large variations, which can indicate any specific trend of it, these observations, therefore, provide a weak support to the general view that the rainfall in the basin is progressively decreasing.
