| Abstract: | According to the field observation,the grain size,the element and compound analysis of 128 samples,and historical flood records of this area,we studied flood variation indicated by sediments in floodplain of the Jing River in Jingyang reach during deposit of floodplain.The result shows that the sediments which developed well on floodplain of the Jing River in Jingyang reach are mainly of coarse silt and very fine sand.Each component changes obviously in the entire profile,which can clearly reflect the varia... |
