Abstract: | In order to find the changes in rainfall characteristics and to examine the flood damage to lowland rice, a statistical analysis
was carried out on the 40-year daily rainfall record at four rainfall stations (Thangon, Paksane, Seno, and Pakse) in Laos.
The rainfall record was divided into two periods of 20 years each. The results of this analysis revealed the trends in changes
regarding the frequency and the timing of the heavy daily rainfall events at the four stations. In Paksane in particular,
heavy daily rainfall events tended to occur in the latter half of the rainy season. |
