Abstract
Stream temperature is a very important
ecological index. The change of stream temperature
might influence growth rate and survival of fish and
other aquatic organisms, so many researchers have
put emphasis on the study of stream temperature.
This research provides a physical model for
predicting the impact of climate change on stream
temperature, by calculating energy balance. Because
upstream watershed in Taiwan is surrounded with
high and steep mountains, the influence of mountain
shading on solar radiation and long wave radiation is
taken into account in this study. The changes of
temperature and streamflow were derived from the
predictions of four General Circulation Models
(GCMs). The result indicates stream temperature
decreases 2%~9% in August and increases 4%~14%
in November when the concentration of atmospheric
carbon dioxide is doubled.
