Groundwater seepage landscapes from distant and local sources in experiments and on Mars (2015)
Journal Article
Marra, W. A., McLelland, S. J., Parsons, D. R., Murphy, B. J., Hauber, E., & Kleinhans, M. G. (2015). Groundwater seepage landscapes from distant and local sources in experiments and on Mars. Earth surface dynamics ESURF ; an interactive open access journal of the European Geosciences Union, 3(3), 389-408. https://doi.org/10.5194/esurf-3-389-2015

© 2014 Author(s). Valleys with theater-shaped heads can form due to the seepage of groundwater and as a result of knickpoint (waterfall) erosion generated by overland flow. This ambiguity in the mechanism of formation hampers the interpretation of su... Read More about Groundwater seepage landscapes from distant and local sources in experiments and on Mars.

Pressurized groundwater outflow experiments and numerical modeling for outflow channels on Mars (2014)
Journal Article
Marra, W. A., Hauber, E., McLelland, S. J., Murphy, B. J., Parsons, D. R., Conway, S. J., Roda, M., Govers, R., & Kleinhans, M. G. (2014). Pressurized groundwater outflow experiments and numerical modeling for outflow channels on Mars. Journal of Geophysical Research: Planets, 119(12), 2668-2693. https://doi.org/10.1002/2014JE004701

© 2014. American Geophysical Union. All Rights Reserved. The landscape of Mars shows incised channels that often appear abruptly in the landscape, suggesting a groundwater source. However, groundwater outflow processes are unable to explain the recon... Read More about Pressurized groundwater outflow experiments and numerical modeling for outflow channels on Mars.

Flow separation at the inner (convex) and outer (concave) banks of constant-width and widening open-channel bends (2012)
Journal Article
Blanckaert, K., Kleinhans, M. G., Mclelland, S. J., Uijttewaal, W. S., Murphy, B., van de Kruijs, A., Parsons, D. R., & Chen, Q. (2013). Flow separation at the inner (convex) and outer (concave) banks of constant-width and widening open-channel bends. Earth surface processes and landforms : the journal of the British Geomorphological Research Group, 38(7), 696-716. https://doi.org/10.1002/esp.3324

There is a paucity of data and insight in the mechanisms of, and controls on flow separation and recirculation at natural sharply-curved river bends. Herein we report on successful laboratory experiments that elucidate flow structure in one constant-...

Near wake of emergent vegetation patches in shallow flow
Journal Article
Wunder, S., Trevisson, M., Heckele, C., Chagot, L., Murphy, B., McLelland, S., Moulin, F., & Eiff, O. (2018). Near wake of emergent vegetation patches in shallow flow. E3S Web of Conferences, 40, Article 02057. https://doi.org/10.1051/e3sconf/20184002057

Vegetation patches are particularly difficult to quantify in terms of flow resistance due to their complex geometry and topological behaviour under hydrodynamic loading. They not only influence the water level and mean velocities due to the drag they... Read More about Near wake of emergent vegetation patches in shallow flow.
