Abstract

Abstract

The grain-size of suspended particulate matter in the Huanghe Estuary and its adjacent area was investigated with an in situ laser grain-size analyzer in November 2006. The grain-size parameters and distribution patterns vary strongly in the horizontal and vertical directions. The results show that (1) the mean grain-size of the suspended particulate matter ranges from 3.00Φ to 6.41Φ, with an average value of 4.66Φ; (2) the grain-size distribution patterns of the suspended sediment include three types, e. g., monomode, bimode and trimode; (3) C-M patterns suggest that transportation forms of the suspended particulate matter not only include suspended transportation, but bed load transportation. The bed load transportation mainly appeared at the bottom layer. The grain-size pattern and distribution were basically controlled by the Huanghe discharge, hydrodynamics, surface sediment type, and chemical and biological conditions.
