Summary on Grant Application Form |
|
The presence of natural or man-made obstructions within an estuary inlet or coastal embayment can have important water quality consequences for the estuarine and coastal environment. For example, the construction of control structures such as barrages and weirs will generally lead to the partial or complete isolation of the fresh or brackish water upstream of the barrier from the saline water characterising open sea downstream conditions. Similarly, the natural formation of a sediment bar across the estuary mouth (either as a result of summer conditions of low flow or due to upstream abstraction of river water for agricultural or industrial use) limits the upstream extent of tidally-driven saline wedge intrusions and disrupts the natural flushing mechanisms that would operate in the absence of the obstruction. For all of the above circumstances, there are deleterious effects on water quality and dissolved oxygen levels in the affected zones. The present study will consider the effects of these barriers on the estuarine and coastal sediment deposition patterns and it will address the problem of predicting the water exchange resulting from the controlled lowering or raising of the installed barriers (or the dredging and/or removal of the naturally-occurring sediment bars)
