However, pre-dam sediment loads were likely artificially high due to the massive land-use changes of coastal California to rangeland during the nineteenth century. This increase in sediment production is observed in estuarine deposits throughout coastal California, which reveal that sedimentation rates ...
Marine sedimentOrganic matter sourcesC/N and delta C-13Molecular markersThe investigation of organic matter sources is an especially challenging issue for marine coastal areas influenced by both natural and anthropogenic inputs. This study focuses on the provenance of sedimentary organic matter deposited...
The reservoirs that have been built on many of the major rivers trap significant portions of the moving sediment which, in some places, may be remobilized by large floods. Essentially all the river sediment that reaches the Atlantic coastal zone is trapped in estuaries...
The bay barrier in Pui O Bay on the south coast of Lantau Island, Hong Kong was selected as an example for the study of the sediment sources for bay barrier on the Hong Kong coasts. The studies of geomorphology and sediments of the selected bay barriers include the analysis of longshore ...
2. Department of Geography, East China Normal University, ShanghaiAbstract The sediments on the inner shelf of the northern South China Sea, mainly composed of terrigenous fragments, are continually transported herein by streams and floods. The coastal and strait-bottom erosion by waves and currents...

Besides the control of sediment supply by the Selenga River, our data emphasize the significant influences of the Lake Baikal coastal margins in South and North Basin. 展开 关键词: lake baikal siberia last climate cycle mineralogy clays source-area ...
The major routes of sediment transport from land to the open ocean can simply be illustrated through the following sequence: streams, rivers, estuaries, shallow coastal waters, canyons, and the abyssal ocean. It should be noted that significant and long-term storage occurs in river valleys and ...
which must be done over longer periods of time as the bursts become larger but not as frequent. These bursts have been identified in previous sediment transport studies; however, there is currently no understanding of its physical origin. In other words, this phenomenon has been recognized, but...
摘要: The excessive supply of contaminants from urban areas to rivers during the last centuries has led to deleterious impacts on aquatic ecosystems. The sources, the behavior, and the dynamics of these...关键词: Road deposited sediment Lead isotopes Sediment fingerprinting Recent sediment Legacy ...
