The objective of this study was to delineate the spatial distribution of fresh, brackish, and saline groundwater bodies, as well as brine, beneath the Judea Desert, Israel. We used the deep time domain electromagnetic (TDEM) geophysical system, Cycle‐5M, which provides the maximum exploration capability, to depths ∼1.5–2 km below land surface. The study was conducted at 21 locations at the desert plateau, where fresh groundwater flows through the upper aquifers from the replenishment area at… 

Wetland‐Scale Mapping of Preferential Fresh Groundwater Discharge to the Colorado River

A combined near-surface geophysical and direct groundwater chemical toolkit is applied to refine fresh groundwater discharge estimates to the Colorado River through a 4-km2 wetland that borders the town of Moab, Utah, USA.

Use of a time-domain electromagnetic method with geochemical tracers to explore the salinity anomalies in a small coastal aquifer in north-eastern Tunisia

The study area is a small coastal plain in north-eastern Tunisia. It is drained by an ephemeral stream network and is subject to several pollutant discharges such as oilfield brine coming from a

TDEM Soundings as a Tool to Determine Seasonal Variations of Groundwater Salinity (Villafáfila Lakes, Spain)

Interaction between groundwaters with different salinities and lakes show seasonal variations driven by changes in precipitation and evapotranspiration. In the vicinity of Villafáfila lakes, local

Detection of Saline Groundwater Bodies between the Dead Sea and the Mediterranean Sea, Israel, Using the TDEM Method and Hydrochemical Parameters

A Time Domain ElectroMagnetic (TDEM) survey coupled with hydrogeological information was carried out along the Be’er Sheva valley between the Mediterranean Sea and the Dead Sea base levels, aiming to

Assessment of the state of soils, shallow sediments and groundwater salinity in Abi, Cross River State, Nigeria

Abi area in Nigeria borders the salinity enriched Lower Benue Trough (LBT) and plans are currently underway to extend large-scale irrigation facilities under construction in the LBT to Abi area. In

Airborne and ground‐based transient electromagnetic mapping of groundwater salinity in the Machile–Zambezi Basin, southwestern Zambia

The geological and morphological evolution of the Kalahari Basin of Southern Africa has given rise to a complex hydrogeological regime that is affected by water quality issues. Among these concerns

Geophysical Characterization of Aquifers in Southeast Spain Using ERT, TDEM, and Vertical Seismic Reflection

We assess the effectiveness of complementary geophysical techniques to characterize a Jurassic dolomite confined aquifer at Loma de Ubeda, Spain. This aquifer, which is penetrated by wells in the

A magnetotelluric transect across the Dead Sea Basin: electrical properties of geological and hydrological units of the upper crust

Oblique shear directions along the left lateral strike-slip Dead Sea transform (DST) fault caused the formation of the Dead Sea Basin (DSB), one of the world’s largest pull-apart basins. The Dead



Geophysical (Time Domain Electromagnetic Model) delineation of a shallow brine beneath a freshwater lake, the Sea of Galilee, Israel

The Sea of Galilee is a freshwater lake, into which saline water emerges through onshore and offshore springs and through flux from the lake's sediments. The novel surface marine modification of the

Factors controlling the configuration of the fresh–saline water interface in the Dead Sea coastal aquifers: synthesis of TDEM surveys and numerical groundwater modeling

Abstract. TDEM (time domain electromagnetic) traverses in the Dead Sea (DS) coastal aquifer help to delineate the configuration of the interrelated fresh-water and brine bodies and the interface in

Detection of subsurface brines, freshwater bodies and the interface configuration in-between by the time domain electromagnetic method in the Dead Sea Rift, Israel

Abstract High radon fluxes in the seismically active Dead Sea Rift seem to be affected by the hydrological system and the different salinities of groundwater bodies involved. The time domain

Transient Electromagnetic Sounding for Groundwater

The feasibility of using the transient electromagnetic sounding (TS or TDEM) method for groundwater exploration can be studied by means of numerical models. As examples of its applicability to

Transient groundwater-lake interactions in a continental rift: Sea of Galilee, Israel

The Sea of Galilee, located in the northern part of the Dead Sea rift, is currently an intermediate fresh-water lake. It is postulated that during a short highstand phase of former Lake Lisan in the

Basin-scale migration of continental-rift brines: Paleohydrologic modeling of the Dead Sea basin

It was suggested that brine of the Dead Sea rift has originated from a residual product of intensively evaporated seawater that invaded the rift, precipitated halite, and later interacted through

A Joint TEM‐HLEM Geophysical Approach to Borehole Siting in Deeply Weathered Granitic Terrains

Although the results appear to indicate that the single-loop TEM method could be used independently for borehole sitting in deeply weathered granitic terrains and that the weathering profile over granite can be mapped using TEM depth soundings of appropriate observational bandwidth, it is recommended a joint electromagnetic approach for optimal well sitting.
