From Plot to Regional Scales: Interactions of Slope and 1 Catchment Hydrological and Geomorphic Processes in the 2 Spanish Pyrenees

19 The hydrological and geomorphic effects of land use/land cover changes, 20 particularly those associated with vegetation regrowth after farmland abandonment were 21 investigated in the Central Spanish Pyrenees. The main focus was to assess the 22 interactions among slope, catchment, basin, and fluvial channel processes over a range 23 of spatial scales. In recent centuries most Mediterranean...

Recent Variations of Snowpack Depth in the Central Spanish Pyrenees

The evolution of snow depth in the central Spanish Pyrenees was analyzed using measurements from 106 snow stakes over a period of 14 yr (1985–1999). Relationships were considered between the regional series of snow depths at the end of winter and in the middle of spring with respect to precipitation and temperature in previous months. Both variables explained a large percentage of the interannu...

Mobility of Natural Radionuclides and Selected Major and Trace Elements along a Soil Toposequence in the Central Spanish Pyrenees

Natural gamma-emitting radionuclides (U, Ra, Th, Pb) and selected major and trace elements (Ca, K, Mg, Na, Fe, Al, Mn, Pb, Ba, Zn, Sr, Li, Co, Ni, Cu, Cr, Cd) were determined in a soil toposequence along a mountain slope of the Tertiary Flysch landscapes in the Central Spanish Pyrenees. A variety of basic properties were also measured from the soil profiles. Mean radioisotope activities (Bq kg ...

Runoff generation in an intensively disturbed, abandoned farmland catchment, Central Spanish Pyrenees

This paper studies the hydrological response to rainstorm events of a small experimental catchment in the Central Spanish Pyrenees. The Arnás catchment was cultivated until 40 years ago, and then abandoned and affected by plant recolonisation, especially shrubs. A rainfall of a few mm is enough to produce a sudden increase in discharge, due most probably to the steep gradients and the small siz...

Comparison of δ(13)C and δ(18)O from cellulose, whole wood, and resin-free whole wood from an old high elevation Pinus uncinata in the Spanish central Pyrenees.

δ(13)C and δ(18)O values from sapwood of a single Pinus uncinata tree, from a high elevation site in the Spanish Pyrenees, were determined to evaluate the differences between whole wood and resin-free whole wood. This issue is addressed for the first time with P. uncinata over a 38-year long period. Results are also compared with published isotope values of α-cellulose samples from the same tre...
