Analysis of the rainfall conditions inducing torrential activity in the Portainé catchment (Eastern Pyrenees, Spain)

Application and validation of different geomatic techniques for the quantification of mass-wasting processes in a torrential catchment in the Axial Pyrenees

Analysis and Predictability of the Hydrological Response of Mountain Catchments to Heavy Rain on Snow Events: A Case Study in the Spanish Pyrenees

From June 18 to 19, 2013, the Ésera river in the Pyrenees, Northern Spain, caused widespread damage due to flooding as a result of torrential rains and sustained snowmelt. We estimate the contribution of snow melt to total discharge applying a snow energy balance to the catchment. Precipitation is derived from sparse local measurements and the WRF-ARW model over three nested domains, down to a ...

Atmospheric Patterns Leading Major Avalanche Episodes in the Eastern Pyrenees and Estimating Occurrence

The occurrence of major avalanche episodes in the Eastern Pyrenees (NE Spain) is estimated by means of the Poisson and the negative binomial distributions, assuming that they are rare events. The differences observed in their spatial distribution along the seven regions in which Eastern Pyrenees have been divided, suggests us to look for spatial variations in the relationship between extreme av...

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...

Rainfall Characteristics of the Liudaogou Catchment on the Northern Loess Plateau of China

The objectives of this study were to understand the rainfall characteristics of thewind-water erosion crisscross region on the northern Loess Plateau, China, to provide basisfor the studies on mitigation of soil erosion, estimation on surface water resources andlocal hydrological circle, etc. The Liudaogou Catchment with representative climatic andhydrologic conditions of wind-water erosion cri...
