Abstract:
The hyporheic zone of a river is a unique and dynamic environment that plays an important role in both physical and ecological river processes. Recently, river restoration practitioners have started to acknowledge its importance, but face a lack specific guidance to incorporate hyporheic exchange into restoration practices. In this study we outline a physical-based framework that links hydromorphological attributes of the river system to potential hyporheic exchange at a restoration site. Attributes cover a range of hydromorphological processes operating across different spatial scales (i.e. catchment to geomorphic features) and are classified according to their impact on physical hyporheic functioning. The classification was developed using detailed hyporheic flow data for a range of restored and unrestored sites across the UK. It provides a simple-to-use method to determine if the enhancement of hyporheic flow should be a goal of restoration and suggests reach and catchment-based restoration measures to include in proposed work.
