I am fascinated by the functioning of the natural environment, in particular by sediment dynamics in catchments. I am soil scientist and geomorphologist by training. I have explicitly worked on various timescales, ranging from days to millennia, identifying time-scale gaps between processes and their effects.
Hydrological and sediment connectivity is an emerging subject in geosciences that I work on; it is the number and length of water and sediment pathways, from source to sink, in a landscape. I am particularly interested in how connectivity changes over time and space.
Ecogeomorphology is a subject that I have started working on recently. For example in so-called ‘tigerbush’ ecosystems, that feature a banded or patchy pattern of vegetation and bare soil patches, feedbacks between vegetation, soil, hydrology and geomorphology are important; understanding these feedback is crucial for sustainable ecosystem management.
Finally, I work on land degradation processes, or, the more positive side of the coin, sustainable land use through soil and water conservation (SWC) measures and novel landscape design, for example incorporating (dis)connectivity in the landscape.
I use a range of methods, including field investigation, laboratory tests and modelling. I am experienced in the event-based soil erosion model OpenLISEM as well as in landscape evolution model LAPSUS, to which I added fluvial processes and, recently, a dynamic vegetation module.
I have extensive research experience in dryland areas such as (South-East) Spain, but also in Ethiopia and China. Furthermore, I enjoy cooperating with researchers worldwide, as well as discussing my research at international meetings and conferences.
