Journal Article
Vitale, A. J., García, M. H., Fernández, R., Vitale, A., Parker, G., & Garcia, M. (in press). Hydraulic resistance in mixed bedrock-alluvial meandering channels. Journal of Hydraulic Research, 1-16. https://doi.org/10.1080/00221686.2020.1780489

We present an experimental analysis of hydraulic roughness variations due to changes in alluvial cover in a mixed bedrock-alluvial meandering channel with larger bedrock roughness than alluvial roughness. Three sets of experiments were conducted in a... Read More about Hydraulic resistance in mixed bedrock-alluvial meandering channels.

Experiments on patterns of alluvial cover and bedrock erosion in a meandering channel (2019)
Journal Article
Fernández, R., Parker, G., & Stark, C. P. (in press). Experiments on patterns of alluvial cover and bedrock erosion in a meandering channel. Earth surface dynamics ESURF ; an interactive open access journal of the European Geosciences Union, 7(4), 949-968. https://doi.org/10.5194/esurf-7-949-2019

In bedrock rivers, erosion by abrasion is driven by sediment particles that strike bare bedrock while traveling downstream with the flow. If the sediment particles settle and form an alluvial cover, this mode of erosion is impeded by the protection o...

Input-variable sensitivity assessment for sediment transport relations (2017)
Journal Article
Fernández, R., & Garcia, M. H. (2017). Input-variable sensitivity assessment for sediment transport relations. Water Resources Research, 53(9), 8105-8119. https://doi.org/10.1002/2016wr020249

A methodology to assess input‐variable sensitivity for sediment transport relations is presented. The Mean Value First Order Second Moment Method (MVFOSM) is applied to two bed load transport equations showing that it may be used to rank all input va...
