Field and laboratory experiments were conducted to research the phosphorus adsorption by the pond sediments in the pond system in a headstream watershed.

To evaluate accumulation and release potential of some pollutants in pond′s mud as affected by land use, four complete mud cores(0~50 cm) were collected from four small ponds with different land use in Zhejiang province, southe.

A Trial on Cement Solidification of Sludge with High Content of Cd;

Effect of Salt Release from Sediment on Water Quality of Beitang Reservoir;

Impact Factors on Salt Release from Beitang Reservoir Sediment;

In an attempt to summarizing the previous work, and analyze the hydrometeorological, geological and hydrogeological condition of Beitang reservoir, in Tianjing city, the hydraulic conductivity (K) of the reservoir bottom stratum and its spatial random distribution were determined by using field hydro-geological investigation and grain size analysis in the laboratory.
