Plain river dredging of Hangzhou-Jiaxing-Huzhou Area is an important part of river regulation in Zhejiang Province, and it is a matter requiring long-term concern. Through deposition and Dredging surveys and carry out analysis and research to identify the causes of siltation and dredging problems, it guides our targeted to reduce siltation, to improve the organization and management of dredging projects,...
Marine environment is an important component of natural environment. It is a basic guarantee to realize the sustainable development of marine economy. The increasing marine environmental pollution causes many bad results. The paper selected the contents of inorganic nitrogen, activated phosphate, oil, mercury (Hg), lead (Pb), arsenic (As) and copper (Cu) as evaluation indexes. Then it established...
The present study was to investigate the trophic state of Nansi Lake, a shallow lake employed in the South-to-North Water Diversion Project in China. Based on water transparency, total phosphorus (TP) and chlorophyll a (chl a) concentration, the modified method of Carlson's trophic state index (TSIM) was applied to assess the lake's trophic status. The Shannon diversity index of phytoplankton was...
Dredging is essential for the maintenance and development of ports, harbors and waterways. As the developing of harbors and waterways in China, more and more dredged material is produced, and gradually considered as a nature resource. This paper focuses on introducing the management and utilization of enormous dredged material in deepwater channel regulation project of Yangtze Estuary during past...
The problem of water source pollution has become more and more serious in Wuxi and Suzhou district. It is urgent to monitor water quality widely and rapidly, which is the advantage of remote sensing. However, water sources around cities are inland waters in which chlorophyll-a and suspended matter concentrations are hard to retrieve accurately from remote sensing just by using empirical methods. To...
