Numeric modeling of the physical and hydrodynamic processes of the Magdalena River’s mouth (Colombia).
Probabilistic model for the navigability risk at the Magdalena River (Colombia).
A multi year global database of meandering rivers.
A new classification scheme of meandering rivers, which would potentially complement the Brice (1975) scheme.

A methodology to estimate soil erosion rates in developing countries at country scale.
This study proposes a RUSLE-based method to estimate soil erosion rates at country scale for developing countries, which commonly exhibit temporal and spatial limitations in ground-based measurements of the fundamental parameters describing such model.
The method we proposed mainly uses up-to-date publicly available datasets. A paper that is under review elaborates on the preprocessing of such data, focuses on the R and C factor of the RUSLE model because they are critical parameters for the model in developing countries, and suggests the use of the sediment delivery ratio as a proxy parameter to validate the RUSLE
model. This video shows our preliminary results.
Environmental cost of soil erosion in Peru.
The environmental cost associated to both onsite and offsite soil nutrients loss triggered by soil erosion was estimated for two large basins in Peru. A paper related to this study is in preparation.
