Description
Increasing frequency of heavy rainfall associated with climate change such as global warming is pointed out, subsequently impacts on its various industries are concerned. In Okinawa, since to the high temperature and heavy rainfall of the subtropical climate, erosion frequency occurs that weak red soil (Kunigami Maage) flows out from agricultural land, construction site and so on.This serious problem has not been resolved since 1950s. Moreover, not only limited in Okinawa, but also the weak soil erosion problem occurs in Kyushu Island, which also should be concerned in the future.<br> In this study, by analysing the annual occurances variation of heavy rainfall and the mean temperature in recent 50 and 100 years, we are trying to grasp the current state of advancing subtropical in Kyushu. In addition, by taking field test at farmland in Ginoza-son, Kunigami-gun, Okinawa and investigating the relation among rainfall, soil erosion and volumetric water content, we are trying to grasp the soil erosion mechanism with climate change.
