2010年7月22日的地图（PDF文件）显示，预计在这张ISS的照片拍摄当天（2010年7月23日），该“油污”地带的北部边缘将对着三角洲堆积起来。

The map from July 22, 2010, (PDF file) shows that on the day this image was taken from the ISS (July 23, 2010), the north edge of the “oiled” zone was expected to bank up against the Delta.

由于泥沙的沉积，河床抬升，水深变小，水流速度场在整个堆积扇上明显增大，并在三角洲前缘出现明显的绕岛环流和河流分叉现象。

The water depth reduced due to deposition, the water flow velocity upon the alluvial sector increased obviously and at the front of the delta exists currents around the sand bar.

辫状三角洲体系的平原相基本上由辫状河道沉积组成，三角洲前缘及前三角洲相带则以快速堆积、滑塌及浊流沉积为主。

Braid delta systems mainly consist of braid river deposits in delta plain facies, rapid accumulation deposits, slump deposits and turbidites in delta front and prodelta facies.
