Uonogawa field trip

Gauging station on the Uonogawa at Horinouchi (A = 1400 km2)

Currently Team Hydrology are working with data from the Uonogawa River in the upper reaches of the Shinano River. This river basin has especially heavy snowpack in winter and very rich water resources which are used downstream throughout the Niigata Plain for rice paddy agriculture.

Today we visited several hydrometric monitoring stations that measure streamflow, precipitation, and snowpack in the basin, as well as the major dam site within the basin at Kuromatagawa Dam. When using data for hydrological simulation, it is important to see first-hand where and how the data has been collected!
