Erosion and Siltation

Erosion and Siltation

The Tyne catchment is characterised by relatively steep hills and impermeable rocks. This means that rainfall, which can be heavy and intense, runs off surfaces quickly into our river system, taking fine sediments and pollutants with it. Pollutants are varied, but linked to land use; for example pesticides and slurry from agriculture, fine sediments from forestry, or hydrocarbons and salt from roads.Habitats map button

We work to reduce the levels of fine sediment and pollutants entering the river.  We target areas where the amount of siltation is the highest or where silt-sensitive species, such as the Freshwater Pearl Mussel, Salmon and Trout, can be found.

We do not attempt to tackle natural erosion, only that which has been caused by man-made practices.  Some erosion is required in a healthy river. When erosion is aggravated by land use, then we look for permissions and funds to address the situation. Please take a look at the following examples of our work on problem sites for erosion and/or siltation.
