Managed Aquifer Recharge At Llobregat Valley (Ne Spain)
Field trip leaders:
- Sara Figueras (Institut Cartogràfic i Geològic de Catalunya)
- Victòria Colomer (Agència Catalana de l’Aigua)
- Morning: Visit to Water Museum and explanation of the evolution of water supply infrastructures. Visit to the recharge system of Sant Vicent dels Horts where many hydrological geochemical and geophysical surveys have been conducted.
- Afternoon: Return to Barcelona visiting the waste water treatment plant and the hydraulic barrier against saltwater intrusion in El Prat de Llobregat Delta. The trip will end in the F.C. Barcelona Camp Nou stadium to know the engineering system for grass irrigation and a geophysics survey carried out as a contribution on the seismic hazard studies done in Barcelona city.
|09:00||Departure from “Palau de Congressos de Catalunya”|
Guided visit to a contemporary museum devoted to water, intended to promote knowledge and values through a living, learning and leisure experience. In this site, we will know the history of Barcelona water supply and the history about the exploitation of Llobregat aquifers.
SANT VICENÇ DELS HORTS PONDS
Visit of an artificial aquifer recharge system located in the low Llobregat Delta. The system, is one of the pioneer zones in Spain and was designed to receive water from the Llobregat River and reused water from El Prat de Llobregat treatment plant. It includes recharge wells and decantation and infiltration ponds. Since 2009 the ponds have been exploited and operated. The geophysical studies conducted in the area have been useful to evaluate the relation between the electrical resistivity and the hydraulic parameters besides to monitor the non-saturated to saturated soil process after the beginning of the infiltration.
|14:00||LUNCH at Sant Vicenç dels Horts|
|15:30||EL PRAT DE LLOBREGAT TREATMENT PLANT
This plant is one of the largest in Europe, traits wastewater from 2 Mhab and 100 Mm3/y. After a biological treatment with removal nutrients in addition to ultrafiltration and osmosis processes, reclaimed water can be injected into the aquifer through a hydraulic barrier to prevent the saline intrusion. In this site, environmental uses of water, engineering of the treatment plant and geophysical studies in the injection and control wells will be presented.
|17:00||ENVIRONMENTAL AND ENGINEERING GEOPHYSICS ON THE CAMP NOU STADIUM, FUTBOL CLUB BARCELONA
The visit of this site focuses to two parts:
At the end of this site, you can visit the Camp Nou installation.
