Combining of MASW and GPR Imaging and Hydrogeological Surveys for the Groundwat...
Alcalá, Francisco Javier; Martínez-Pagán, Pedro; Paz, Maria Catarina; Navarro, Manuel; Pérez-Cuevas, Jaruselsky; Domingo, FranciscoThis paper conceptualizes and evaluates the groundwater resource in a coastal urban area hydrologically influenced by peri-urban irrigation agriculture. Adra town in southern Spain was the case study chosen to evaluate the groundwater resource contributed from the northern steep urban sector (NSUS) to the southern flat urban sector (SFUS), which belongs to the Adra River Delta Groundwater Body (ARDGB). The meth...
Ground penetrating radar attenuation expressions in shallow groundwater research
Paz, Maria Catarina; Alcalá, Francisco Javier; Ribeiro, LuísThe electromagnetic-wave attenuation coefficient determines the overall resolution and effective penetration depth of ground penetrating radar (GPR) surveys. Despite this relevance to the design of proper GPR surveys, the attenuation expressions are rarely used in the applied shallow groundwater research (SGR) literature. This work examines the status of the attenuation expressions in SGR. For this, 73 GPR case...
Integrated MASW and ERT Imaging for Geological Definition of an Unconfined Allu...
Paz, Maria Catarina; Alcalá, Francisco Javier; Medeiros, Ana; Martínez-Pagán, Pedro; Pérez-Cuevas, Jaruselsky; Ribeiro, LuísThis paper integrates multichannel analysis of surface waves (MASW) and time-lapse electrical resistivity tomography (ERT) to define aquifer geometry and identify transient groundwater features of the Cascalheira Stream Basin Holocene alluvial aquifer (aquifer H), which contributes to the Santo André Lagoon, part of a coastal groundwater-dependent ecosystem (GDE), located in southwest Portugal. MASW measures sh...
