Study of Comparing Sedimentology in High-sinuosity River a nd Low-sinuosity River

Abstract: High-sinuosity river are low-sinuosity river aye two chief meandering r ivers.Taking Jingjiang river for example,the article expounds sedimentary unit and chara cteristic of two different kinds of meandering river with comparing sedimentolog y me thod.Because of difference in river nature,flow and boundary condition,①up and down stream of Jing Jiang take the shape of point bar,but the disparities exist in shape,distributive spot,maturity,grain size,sedimentary structure,s e ction texture,micro-morphologic unit.②many river islands exist in up an d down stream of Jingjiang river,but their cause of formation,scale,evolution nat ure an d sedimentary texture are different,③crevasse splay is only formed in up strea m of Jingjiang river and development degree is within equality two banks.The dow n stream of Jingjiang river and development degree is within equality two banks.The dow n stream of Jingjiang river don't exist crevasse splay.④ox-bow lakes exist only in d own st ream of Jingjiang river and northern bank is mainly distributive spot of ox-bow lake.
