Surface sediment grain-size distribution and sediment transport in the subaqueous Mekong Delta, Vietnam

Sediment Trapping Pathways and Mechanisms through the Mekong Tidal River and Subaqueous Delta

A long-term goal of our sediment transport and deposition investigations is to link sediment-transport processes to the formation and preservation of event beds in sediment deposits. The general aim of this project is to investigate how forcing processes affect the sediment-transport dynamics that act to effect the delivery and retention of fine-grained sediment through tidal rivers and in shal...

Grain size distribution effects on phosphate sorption by fluvial sediment: implications for modelling sediment- phosphate transport

A sensitivity analysis was performed on a sediment-phosphate transport model by determining the phosphate sorption characteristics of separated size fractions and prepared size distributions of fine-grained ( < 64 jum) river sediment typically transported in two southern Ontario streams. The Langmuir equation was used to quantify phosphate release from the sediment. Results of the study indicat...

Subaqueous sediment gravity flows undergoing progressive solidification

Highly concentrated sediment flows may occur following failures of loosely compacted, granular slopes underwater or in waterfront areas. The mobility of such sediment flows is of considerable interest to the integrity of coastal fills, underwater pipelines and other such marine facilities. However, the physics of highly concentrated sediment-water mixtures is complex in nature and calls for mor...
