A catchment s nutrient model SWAT was used in this paper to examine changes in the nutrient sedimentation and transportation in a hundred-year time scale,and Hong Lake Basin,located in the middle reach of Changjiang River was chosen as the study area.

Diffusional nutrient fluxes contribute to the benthic nutrient fluxes slightly.

Investigation of sedimentation fluxes, TEQ and sources of PCDD/Fs in Qingdao coastal sea.;

Based on the 210Pb method, sedimentation rates and sedimentation flux were measured in the Jiaozhou Bay of the Shandong Peninsula.

Sedimentary flux of Lake Taibai,Hubei Province and correlations with precipitation and human activities in its catchment during the last century;

Firstly, the remnant sedimentary flux has been calculated basing on Later Cenozoic isopach map of Chengdu basin which has been made from the borehole data in the basin by Sufer software.

Based on drilling, seismic and outcrop data, a sedimentary flux study is conducted on Tertiary deposits in south-west depression of Tarim Basin, plane isograms of sedimentary flux at different periods are plotted.
