CRAHI - Centre de Recerca Aplicada en Hidrometeorologia

 

El principal objectiu del CRAHI és desenvolupar metodologies i sistemes per donar resposta científica i tècnica a les necessitats en el camp de la previsió hidrometeorològica, la gestió dels recursos i els riscos hídrometeorològics, incloent l’impacte dels efectes del canvi climàtic. Per això es combinen les observacions i el processat de dades de teledetecció amb la modelització dels processos i el disseny d'aplicacions informàtiques operacionals de previsió i alerta en temps real pel suport a la presa de decisions i la gestió de recursos i emergències.

El CRAHI orienta su actividad a dar respuesta científica y tecnológica a las necesidades en el campo de la gestión y la previsión hidrometeorológica. En particular al desarrollo de algoritmos y modelos de previsión de los procesos que controlan el ciclo del agua superficial.

The CRAHI focuses its activity on providing scientific and technological support in the area of hydrometeorological management and forecasting, particularly on developing models of the processes that drive the cycle of surface waters.

  • Implementation of hydrometeorological thresholds for regional landslide warning in Catalonia (NE Spain) 

    Palau Berastegui, Rosa Maria; Berenguer Ferrer, Marc; Hurlimann Ziegler, Marcel; Sempere Torres, Daniel (Springer, 2023-10)
    Article
    Open Access
    Soil 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 ...

    The 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 

    Ferrer Boix, Carles; Scorpio, Vittoria; Martín Vide, Juan Pedro; Núñez González, Francisco; Mora Mur, Daniel (2023-09)
    Article
    Restricted access - publisher's policy
    This 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 

    Bregoli, Francesco; Medina Iglesias, Vicente César de; Bateman Pinzón, Allen (2021-04)
    Article
    Open Access
    Time 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 

    Meléndez Landaverde, Erika Roxana; Sempere Torres, Daniel (2022-10)
    Article
    Open Access
    The 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 ...
