Abstract


The northern and north-eastern (Eastern Ghats), the southern and south-eastern sides of the basin are dominated by rugged discontinuous hills, with altitudes ranging from 300 to 1,000 meters. Based on the quantitative analysis on LULC, it was observed that a rapid growth in built-up land between 1973 and 2003 while the periods between 1993 and 2003 witnessed a reduction in this class. It is expected that the expansion of built-up area will follow the same trend from the year 2003 onwards. Considerable changes in agricultural pattern in this study area though there is not much changes in water resources may be an indication that the influence of climate change induced effects are expected to be vital factor in Bhavani River Basin. Considerable changes in agricultural pattern in this study area though there is not much changes in water resources may be an indication that the influence of climate change induced effects are expected to be vital factor in Bhavani River Basin. However this should be further validated by the analysis of socio-economic, hydro-meteorological and other field data pertaining to the study area.

*2016 Journal Impact Factor was established by dividing the number of articles published in 2014 and 2015 with the number of times they are cited in 2016 based on Google Scholar, Google Search and the Microsoft Academic Search. If ‘A’ is the total number of articles published in 2014 and 2015, and ‘B’ is the number of times these articles were cited in indexed publications during 2016 then, journal impact factor = A/B.
