Ambili T ^[5] | George D'cruz F

Abstract: The present study was carried out to determine the hydrographical characteristics of Ayiroor river water in South India for a period from February 2014 to January 2015. Ayiroor river (8.75N & 76.71E) is the smallest river in Southern Kerala, lies between 8.75N latitude and 76.71E longitude and drains an area of 66 Sqr. Km. It is about 17 Km in length, originate from Vilangara in Navayikulam, flowing through Thiruvananthapuram district and empties in to the Edava- Nadayara Kayal. Water samples collected from three sampling stations (Station1-Panayara, Station2-Ayiroor and Station3-Nadayara) were analyzed for various physicochemical parameters like temperature, pH, total dissolved solids, salinity, alkalinity, dissolved oxygen, dissolved carbon dioxide, nitrate phosphate and sulphate. The study revealed that the hydrographical parameters of water exhibited considerable seasonal variations and the river water is not severely polluted and useful for various purposes.
