587 mm of rainfall in July

This July has had more than twice the usual rainfall, with 587 mm at the Miomote Amedas Station compared to an average of 263 mm (1981-2010). Maximum daily precipitation was 119 mm on July 24, and maximum hourly precipitation was 48 mm on July 18th. While the above hydrograph only shows data until July 21, it shows that the rainfall did not produce any particularly large floods. Instead there were multiple floods and peaks with a moderate stage of 0.8 m to 1.1 m.

The above two photographs show the water to be running very clear. However, the intense and localized storm of July 18 (max. 48 mm/h) seems to have been centered in the tributary basin which joins the main stem of Takiya River by the bridge abutment shown in the photographs below. There is a large accumulation of bedload sediment at the confluence below the bridge as the main stem did not appear to have the flow required to transport the sediment downstream.
