THE CHANGES IN STREAM WATER TEMPERATURE AND WATER QUALITY PARAMETERS DURING RAINFALL EVENTS IN FORESTED WATERSHEDS: SCALING OF OBSERVATIONS
We studied the changes in stream water temperature (Tw) and water quality (Wq) during rainfall events in forested watersheds. The parameters ofWq (88, DOC, N03--N, DTN, Na+, 8i and r) were observedinfour regionsof Japan from June 2004 to December 2005. The R values between Tw and those Wq parameters...

| Summary: | We studied the changes in stream water temperature (Tw) and water
quality (Wq) during rainfall events in forested watersheds. The parameters ofWq
(88, DOC, N03--N, DTN, Na+, 8i and r) were observedinfour regionsof Japan
from June 2004 to December 2005. The R values between Tw and those Wq
parameters and between specific discharge (Qs) and Wq were positive, exceptfor
the negativeones (Na+ and Si). Similarto the relationbetweenQs vs. Tw, hysteretic
loops in the relations between Qs vs. those Wqparameters were clockwise,
exceptfor Na+ and Si as counter-clockwiseloops. This indicatesthat the'surface
and subsurface flows contain higher concentrations of SS, DOC, IC, N03--N and
DTN. To the contrary,the deeperpathwayscontainhigherconcentrationsof Na+
and Si. These results suggest that the changes in Tw and Wq could be used to
interpret theflow paths. |
