Modeling complex flow structures and drag around a submerged plant of varied posture

Here is the link to our paper in Water Resources Research (https://doi.org/10.1002/2016WR020186).

In the paper we combined flume and numerical model experiments to improve the process-understanding of flow structures and drag around a submerged plant. The paper provides an examination of the feedbacks between flow and vegetation dynamics, through:

– an understanding of time-dynamic and time-averaged plant motion characteristics;
– quantification of the three-dimensional mean and turbulent flow, and;
– an evaluation of how accurately the numerical model can predict measured flow.

Using image analysis techniques, we quantified the time‐averaged plant posture and used this to predict flow around a submerged riparian plant. Results highlight the dynamic nature of the drag response with changes in plant posture.

The flume experiments were undertaken in the Department of Geography, Environment and Earth Sciences, University of Hull (https://www.hull.ac.uk/faculties/subjects/geography.aspx).

The paper was selected as an ‘Editors’ Highlight‘ (see here).
