In October, another peak was recorded due to autumn rainfall. The various
streams that contribute to the main river are torrential in nature, and seasonal
torrentiality of the Ubaye can be attributed to the pattern of the rainfall in the area.
This also results in a high rate of erosion and accumulation of debris and sediments
downstream. Torrential flood flows occurred generally from April to November,
with the peak during May and June when spring floods arise due to excess rainfall
and a higher rate of snowmelt.
April, May, June, and July were used to compare the discharge value with
precipitation and temperature, and they are sensitive months with regard to the
discharge parameter.
By observing the results of May 2008, when the maximum discharge occurred,
it can be seen that the precipitation was 156 mm and the maximum temperature
