“…Image analysis, from spatially distributed resistances at specific time intervals, is through timelapse electrical-resistivity tomography (TLERT). TLERT's various applications have attracted many researchers: Barker and Moore (1998) for physical-model tests of groundwater flow and contamination; Kemna et al (2002), Cassiani et al (2006), and Oldenborger et al (2007) for tracertest study of aquifers; Olofsson and Lundmark (2009) for impact monitoring of roadside-soil de-icing-salt in saltwater investigation; and Ogilvy et al (2009) for study of near-coast saltwater intrusion; in each, TLERT images relate change in salinity to transport of solutes.…”

Time-lapse resistivity measurements and groundwater geochemistry were used to study salinity effect on groundwater aquifer at the ex-promontory-land of Carey Island in Malaysia. Resistivity was measured by ABEM Terrameter SAS4000 and ES10-64 electrode selector. Relationship between earth resistivity and total dissolved solids (TDS) was derived, and with resistivity images, used to identify water types: fresh (ρ e > 6.5 m), brackish (3 m < ρ e < 6.5 m), or saline (ρ e < 3 m). Long-term monitoring of the studied area's groundwater quality via measurements of its time-lapse resistivity showed salinity changes in the island's groundwater aquifers not conforming to seawater-freshwater hydraulic gradient. In some aquifers far from the coast, saline water was dominant, while in some others, freshwater 30 m thick showed groundwater potential. Land transformation is believed to have changed the island's hydrogeology, which receives saltwater pressure all the time, limiting freshwater recharge to the groundwater system. The time-lapse resistivity measurements showed active salinity changes at resistivity-image bottom moving up the image for two seasons' (wet and dry) conditions. The salinity changes are believed to have been caused by incremental tide passing through highly porous material in the active-salinity-change area. The study's results were used to plan a strategy for sustainable groundwater exploration of the island.

“…The use of these techniques has been increasingly focused on their ability to measure, albeit indirectly, changes in moisture content (e.g., Binley et al, 2002;Strobbia and Cassiani, 2007;Deiana et al, 2008;Vanderborght et al, 2013 -for reviews see Huisman et al, 2003;Cassiani et al, 2006b) and solute concentration (e.g., Binley et al, 1996;Kemna et al, 2002;Cassiani et al, 2006a;Perri et al, 2012 -for a review see Kemna et al, 2006). Geophysical inspection was coupled here to local measurements of soil saturation to be obtained by Time Domain Reflectometry (TDR) (Topp et al, 1980;Roth et al, 1990), in order to quantify relevant hydrological processes related to vegetation patterns.…”

Abstract. Land fallowing is one possible response to shortage of water for irrigation. Leaving the soil unseeded implies a change of the soil functioning that has an impact on the water cycle. The development of a soil crust in the open spaces between the patterns of grass weed affects the soil properties and the field-scale water balance. The objectives of this study are to test the potential of integrated non-invasive geophysical methods and ground-image analysis and to quantify the effect of the soil-vegetation interaction on the water balance of fallow land at the local-and plot scale.We measured repeatedly in space and time local soil saturation and vegetation cover over two small plots located in southern Sardinia, Italy, during a controlled irrigation experiment. One plot was left unseeded and the other was cultivated. The comparative analysis of ERT maps of soil moisture evidenced a considerably different hydrologic response to irrigation of the two plots. Local measurements of soil saturation and vegetation cover were repeated in space to evidence a positive feedback between weed growth and infiltration at the fallow plot. A simple bucket model captured the different soil moisture dynamics at the two plots during the infiltration experiment and was used to estimate the impact of the soil vegetation feedback on the yearly water balance at the fallow site.

“…Electrical resistivity imaging maps groundwater contamination leachate plumes, contaminant source, migration paths and depth [8]. Moreover, high-density electrical resistivity tomography (ERT) is receiving much attention for near-surface geophysical prospecting and subsurface hydrology evaluation [9][10][11][12][13]. Applications based on ERT either use the earth's resistivity to characterize the site and understand the subsurface geological structure and lithology [14,15] or utilize temporal variations of the earth's resistivity to investigate underlying physical and chemical processes [16][17][18].…”

An integrated geophysical (involving two-dimensional [2D] electrical resistivity) and petrophysical study was conducted in the Precambrian Crystalline Basement area of Iwaro-oka Akoko, southwestern Nigeria. Five 2D resistivity profiles, both around the perimeters and inside the dump, were investigated with maximum lengths of 100 m. Results of the resistivity imaging delineated the leachate plumes as low-resistivity zones, with values ranging from 3 Ω m to 55 Ω m. The coefficient of permeability ranged from 4.33 × 10 -6 to 7. 82 × 10 -3 , and the average porosity ranged from 32 Ω m to 169 Ω m, thus indicating migration of leachate plume to the groundwater due to the high coefficient of permeability and the porosity.Key words: geophysical, geochemical, coefficient of permeability, porosity, leachate IzvlečekNa območju deponije odpadkov, ki leži na ozemlju predkambrijske kristalinične podlage pri kraju Iwaro--oka akoko v jugozahodni Nigeriji so izvedli povezano geofizikalno (z uporabo dvodimenzionalne električne upornosti) in petrofizikalno prospekcijo. Na odvalu in v njegovi bližnji okolici so izmerili pet 2D upornostnih profilov dolžine do 100 m. Na podlagi podatkov upornostnih meritev je bilo mogoče omejiti območja širje-nja lužine iz deponije kot cone nizke upornosti v razponu 3 Ω m to 55 Ω m. Količnik prepustnosti in povprečna poroznost se gibljeta prvi v mejah od 4.33 × 10 -6 do 7.82 × 10 -3 in druga od 32 Ω m to 169 Ω m. Visoke vrednosti količnika prepustnosti in poroznosti nakazujejo poti, po katerih odteka lužina v podtalnico.
