Myin Ywa-Kok ko Canal Field Survey: Tidal Effects on the Lower Eastern Side of Bago River Basin

23 February 2016

UTokyo: Dr. Akiyuki Kawasaki, Dr. Shimozono, Dr. Acierto, Masahiro Kambara, Shin Yonehara
JICA: Hiroyuki Okazaki (SATREPS Project Coordinator at YTU)
YTU: Chit Bo Bo Win, Ye Thu Aung (Master’s Student)
Myanmar Irrigation Department: Mr. Ne Myo Htun (Staff Officer, Thannapin Township)

The field survey for Myin Ywa-Kok ko Drainage canal was done using four-wheel drive (4WD) vehicles due to the rough terrain that are inaccessible or difficult navigation for non-4WD vehicles. There were no established road networks for this area. During dry season, the dry waterway bed served as the road access for these areas along the Myin Ywa Kok ko drainage canal. This dry waterway bed is filled with water during the rainy season that becomes waterway transport using boats.
