Abstract:
In this study, we analyzed the measured data
from 1957 to2009at a station and found flood characteristics
of variation of R River in southChina. The results show that: 1) THE
annual maximum peak discharge in the drainage basin has an increasing trend. The floods occur with
increasing frequency and cycles of floods are getting shorter and shorter; 2) There
are highly positive correlation of annual precipitation, annualrunoff
and flood; the correlation is more closely between flood andrunoff
than flood and annual precipitation; 3) The process of flood is becoming
sharper and thinner because of different factors.
