The West Riverside Hydrogeological Landscape (HGL) is characterised by a series of northwest south-east trending fault blocks that step down to the north-east. The HGL is located west of the Tamar River in Launceston. This is an area of moderate rainfall (680 mm). It is less vegetated but is similar in structure, rock type and regolith development, to the Reed HGL.

Typical lithologies are deeply weathered Jurassic dolerite and fractured Jurassic dolerite, with localised areas of sediment along fault steps.
