Resumen
Badlands are the main sediment source areas affecting
the headwaters of the Gállego and Aragón rivers in the
Central Spanish Pyrenees. These morphologies characterise
the landscape of the Inner Depression, occupying about 15
km2, which represent more than 2.5 % of the Inner
Depression, and their occurrence is mainly associated to
marly outcrops. Beguería (2005) suggested that Eocene

Badlands are the main sediment source areas affecting
the headwaters of the Gállego and Aragón rivers in the
Central Spanish Pyrenees. These morphologies characterise
the landscape of the Inner Depression, occupying about 15
km2, which represent more than 2.5 % of the Inner
Depression, and their occurrence is mainly associated to
marly outcrops. Beguería (2005) suggested that Eocene
Marls are the main sediment source in the Central Spanish
Pyrenees, since this lithology is very sensitive to weathering
and erosion processes.
Previous studies showed that the hydrological response
and sediment yield in mountain humid badland areas are
highly seasonal and are mainly controlled by regolith
development (Regüés and Gallart, 2004). Moreover, rainfall
intensity and rainfall depth are considered to be the most
important factors in determining the hydrological and
sediment response in badland areas (Mathys et al., 2005).
The aim of this work is to study the hydrological and
sediment dynamics in a small catchment with badland areas
by exploring the temporal variability of the hydrological and
sedimentological response, and the relationships between
hydrological and sedimentological variables. [--]
