K. Swetha, G. Jayachandra Reddy, (doi: 10.23953/cloud.ijarsg.403)


The aim of present study is to investigate morphometric analysis of Mun river basin in Thailand. The drainage parameters performed such as linear, aerial and relief aspects of 23 sub watersheds in the concentrated area. The analysis shows that watershed conatins 6611 drainage segments and stream order from I to VII. From that 5275 segments are comes under I order stream, 1025 are II order, 235 are in III order, 57 are IV order, 16 are in V order, 2 and 1 segments are comes under VI and VII order, respectively. The total stream length of Mun river basin is 40353.8 km. The majority of basin contains the bifurcation ratio value is >5. This indicates that geologically hard rock terrain, less infiltration and high flash flood. This analysis helps to better understanding the management and planning activities in 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.
