Runoff Analysis Using Multiple Isotope Tracers in the Iwami River Drainage, Akita, Japan
Entry ID: IWAMIRO

[ Update this Record ]

Summary
Abstract: The rate of direct runoff was determined after a heavy rain fall in
the Iwami River drainage (ca. 100km2), based on changes in hydrogen and
oxygen isotopic ratios and tritium content of river water. The runoff
of dissolved components was also estimated from the change in chloride
content. Isotopic and chemical characters of base flow were examined
at 15 points within the drainage.

The latitude and longitude values of the study area are as follows:
Min. Latitude: 39deg.42min. N
Max. Latitude: 39deg.42min. N
Min. Longitude: 140deg.18min. E
Max. Longitude: 140deg.18min. E
