The sediment transport is affected on a large scale by bioturbation usually when the sediment core is rated we account for sediment focusing.
Recently, I read a paper that presents a model for soil formation. It assess bioturbation. This paper is available here in Researchgate, maybe it can help you.

Bioturbation is a very important process on longer timescales. It basically mixes the soil, and is an important process for moving down soil organic carbon. Interestingly, Charles Darwin already investigated this in his last book. In desert environments, bioturbation by rodents is considered to be important.
I would agree with Johan. Bioturbation is very important specially when a core is considered. It mixes the soil and as a result every other factors depending on the soil or sediment character.
Bioturbation is the reworking and mixing of soil/sediment at
the sediment–water interface by soil living macroinvertebrates mostly and benthic macroinvertebrates and fish, accomplished collectively by burrowing,
feeding, irrigation, resuspension, secretion, excretion and
transporting activities of organisms, which alter the structure and properties of the soil/sediment and thereby influence diffusive
and/or advective transport of both solutes and particulate matters
(Koretsky et al., 2002; De Haas et al., 2005; Janssen et al.,
2005;Meysmanet al., 2006).
To get an idea you may read our paper published in Ecological Engineering: 35 (2009) 1444–1453 (Bioturbation potential of chironomid larvae for the sediment–waterphosphorus exchange in simulated pond systems of varied nutrient enrichment).
