PhD Topic/Title: Does case building by caddisflies affect sediment transport in rivers?


The important influence that animals can have on river geomorphology and hydrology is increasingly being recognised, particularly in regards to large organisms such as fish and beaver. In comparison the effects of invertebrates may seem inconsequential but past research has shown certain types of caddis can have significant effects on sediment transport. This PhD will investigate whether case building behaviour in caddis can alter processes of fine sediment transport in rivers and whether these effects are significant for understanding and managing river systems. The work will involve microscale measurements in laboratory flumes coupled with in situ experiments in rivers across a range of caddis species and grain sizes.
