Turbidity is the measure of the amount of suspended sediment present in the water column.
One of the key ecosystem services provided by saltmarsh is the retention of nutrients and sediments. This trapping of sediment and nutrients can have a positive impact on the quality of water entering the adjacent estuarine system. This sediment is often high in Carbon, hence saltmarsh has the potential to be a significant carbon sink.
Vegetation structure can have an impact on sediment retention as it slows receding water which causes sediment to drop out of suspension. The presence of vegetation, its structure, height and density can influence the amount of sediment trapped.
