Lagrangian-Hamiltonian formalism for cocontact systems
(American Institute of Mathematical Sciences, 2023)
Article
Open AccessIn this paper we present a unified Lagrangian–Hamiltonian geometric formalism to describe time-dependent contact mechanical systems, based on the one first introduced by K. Kamimura and later formalized by R. Skinner and ... -
A user experience evaluation of a mobile application for disseminating site-specific impact-based flood warnings: the A4alerts app
(John Wiley & sons, 2023-11-10)
Article
Open AccessPeople-centred early warning systems must ensure that their warnings are timely, actionable and get to the largest number of exposed individuals in the shortest time possible. Due to the increased access to high-bandwidth ... -
Sediment transport capacity in a gravel-bed river with a sandy tributary
(2023-11-30)
Article
Open AccessBedload transport in a river is a deeply analyzed problem, with many methodologies available in the literature. However, most of the existing methods were developed for reaches of rivers rather than for confluences and are ... -
Implementation of hydrometeorological thresholds for regional landslide warning in Catalonia (NE Spain)
(Springer, 2023-10)
Article
Open AccessSoil moisture plays a vital role in slope stability. As water infiltrates into the soil, shear strength decreases eventually leading to failure. However, most of the existing regional-scale landslide early warning systems ... -
Simulation of flash floods in ungauged basins using post-event surveys and numerical modelling
(John Wiley & sons, 2015-12-01)
Article
Restricted access - publisher's policyThe hydrological and hydraulic processes of the flash flood that affected Atrani village (Amalfi Coast of Southern Italy) on 9 September 2010 are analysed using post-flood surveys and numerical modelling. Observations in ... -
Massive incision and outcropping of bedrock in a former braided river attributed to mining and training
(2023-09)
Article
Restricted access - publisher's policyThis research analyses multiple anthropogenic pressures in the Bernesga River, a gravel-bed river in Northwestern Iberian Peninsula. Among the causes of river incision in Bernesga River are extensive mining during the ... -
The energy transfer from granular landslides to water bodies explained by a data-driven, physics-based numerical model
(2021-04)
Article
Open AccessTime trends and their statistical significance for daily minimum, Tmin, and maximum, Tmax, temperatures recorded at the Fabra Observatory (Barcelona) along 102 years (1917–2018) permit to analyse the evolution of every one ... -
Design and evaluation of a community and impact-based site-specific early warning system (SS-EWS): the SS-EWS framework
(2025-03)
Article
Open AccessThe recent extreme rainfall events in Spain such as the storm Gloria have highlighted the gaps in emergency communication, particularly the disconnect between the available impact-based early warning systems (IBEWSs) and ... -
Coupling between downstream variations of channel width and local pool–riffle bed topography
(2023-01-04)
Article
Open AccessA potential control of downstream channel width variations on the structure and planform of pool–riffle sequence local bed topography is a key to the dynamics of gravel bed rivers. How established pool–riffle sequences ... -
Efectes de les extraccions de material al·luvial sobre el riu i la costa. L’exemple de la Tordera
(2023-01-23)
Article
Open AccessAquest article presenta la síntesi actualitzada de la recerca que s’ha dut a terme a la Tordera des de 2005. S’hi fa un resum dels impactes més importants que ha sofert el riu, principalment de les grans extraccions de ... -
Large wood debris that clogged bridges followed by a sudden release: the 2019 flash flood in Catalonia
(Elsevier, 2023-06)
Article
Open AccessThe aim is the reconstruction of the October 2019 flash flood, that was documented through extensive field work: rainfall (300 mm in just a few hours), flood marks, times of flood passage and witnesses' snapshots and ... -
Compound flood impact forecasting: integrating fluvial and flash flood impact assessments into a unified system
(2022-02)
Article
Open AccessFloods can arise from a variety of physical processes. Although numerous risk assessment approaches stress the importance of taking into account the possible combinations of flood types (i.e. compound floods), this awareness ...
