A stem spacing-based non-dimensional model for predicting longitudinal dispersion in low-density emergent vegetation
in Acta Geophysica
| Description | For the first time, solute transport has been quantified within artificial and real emergent vegetation through simultaneous laboratory measurements of transverse and longitudinal dispersion. We have shown that existing numerical models fail to predict the observed mixing within natural vegetation, particularly for transverse dispersion. This reflects the complexity of processes associated with heterogeneous real vegetation. The existing models are highly sensitive to stem diameter, which has led us to recommend that future models intended for application to real vegetation should be based on probabilistic descriptions of both stem diameters and stem spacing. Further information may be found in Sonnenwald et al. (2017) (Water Resour. Res., 53, doi:10.1002/2016WR019937). We have developed preliminary approaches for representing the observed mixing processes within commercial Computational Fluid Dynamics (CFD) software (Sonnenwald, F., Guymer, I. and Stovin, V., 2019, A CFD-based mixing model for vegetated flows, Water Resources Research, https://doi.org/10.1029/2018WR023628). This work provides practitioners/consultants with the capability to model complex pond geometries with arbitrary vegetation configurations to assess the consequent effects on the flow patterns, solute transport and pollutant treatment potential. |
| Exploitation Route | Academically the laboratory methods, new data and the CFD-based modelling approaches are of interest to the eco-hydraulics research community. For example, those focusing on the use of wetlands to treat contaminated runoff, or those interested in the transport of polluted materials through any vegetated aquatic environments (rivers, coastal etc). From a practitioner perspective, there is interest in our research outputs from both Highways England and Network Rail, as stormwater ponds are used to treat runoff from trunk roads and motorways, and may also be applied to the rail network in the future. Here the interest is in applying the research to optimise pond design to make best use of available land whilst meeting environmental regulatory requirements. |

| Results and Impact | The workshop included presentations from the project team as well as researchers and practitioners/end-users who had not been directly involved in the project. The audience also included academics and practitioners who had not been involved with the project. The event stimulated discussions (and subsequent collaborations) around understanding of processes, measurement/modelling approaches and practical implementation issues/opportunities. |
