| Discharge measurement in the tributary, Takiya 2 (basin area approx. 1km2) |
A walk in the river can teach you many things. Today we walked the several hundred metres from the gauging point on Takiya River to the point where irrigation water is taken, close to the confluence with the Miomote River. Along the way we walked in the flowing water through riffles and pools, observing the changing channel form and channel bed materials, and the ecological environment.
