Conference report
Open AccessEn la presente contribución se describen los sistemas de auscultación de cuatro tipos de movimientos de ladera (corriente de derrubios, deslizamiento profundo, deslizamiento superficial y desprendimiento). El énfasis se ... -
Correlation between the rainfall, sediment recharge, and triggering of torrential flows in the Rebaixader catchment (Pyrenees, Spain)
(2018-10)
Article
Restricted access - publisher's policyThe debris flow (DF) and debris flood (DFD) activity in the Rebaixader catchment (Spanish Pyrenees) is analyzed in this study. The research is focused on how precipitation leads to the triggering of torrential floods and ... -
Critical rainfall conditions for the initiation of torrential flows: results from the Rebaixader catchment (Central Pyrenees)
(Elsevier, 2016-10)
Article
Open AccessTorrential flows like debris flows or debris floods are fast movements formed by a mix of water and different amounts of unsorted solid material. They generally occur in steep torrents and pose high risk in mountainous ... -
Debris-flow early warning system at regional scale using weather radar and susceptibility mapping
(Association of Environmental & Engineering Geologists (AEG), 2019)
Conference lecture
Open AccessRisk mitigation for debris flows at regional scale is a challenge. Early warning systems are helpful in depicting the time and the location of future debris flows so that emergency responders can act in advance before the ... -
Debris-flow forecasting at regional scale by combining susceptibility mapping and radar rainfall
(2015-03-13)
Article
Open AccessThis work presents a technique for debris-flow (DF) forecasting able to be used in the framework of DF early warning systems at regional scale. The developed system is applied at subbasin scale and is based on the concepts ... -
Debris-flow monitoring at the Rebaixader torrent, Central Pyrenees, Spain: results on initiation, volume and dynamic behaviour
(Springer, 2014)
Conference report
Restricted access - publisher's policyThe sophisticated monitoring system installed in the Rebaixader catchment incorporates a total of 6 different stations: four stations recording information on the initiation mechanisms (two meteorological stations and two ... -
Debris-flow monitoring for the set-up of a warning and alarm system: experiences from the pyrenees
(2016-08)
Article
Restricted access - publisher's policyDebris-flow monitoring sites provide many important inputs on their mechanics and strongly improved the understanding on this hazardous process. Monitoring data are the basis for future early warning systems (EWS) and alarm ... -
Debris-flow susceptibility analysis using fluvio-morphological parameters and data mining: application to the Central-Eastern Pyrenees
(2013-06)
Article
Restricted access - publisher's policyBased on debris-flow inventories and using a geographical information system, the susceptibility models presented here take into account fluvio-morphologic parameters, gathered for every first-order catchment. Data mining ... -
