Volume evolution of coseismic deposits under rainfall in 2008 Wenchuan earthquake zone.

Volume evolution of coseismic deposits under rainfall in four valleys (i.e., Bayi, Wenjia, Sujia and Gaojia valleys)in 2008 Wenchuan earthquake zone. After each rainfall, the removed deposit volume is obtained as shown in attached file.2008年汶川地震区4条山谷（即八一沟、文家沟、苏家沟、高家沟）内同震堆积物在降雨作用下的体积演化过程。每场降雨后，均可获取经降雨冲刷移除的堆积物体积，具体数据见附件文件。
