Details of Earth's shallow subsurface—a key component of the critical zone (CZ)—are
largely obscured because making direct observations with sufficient density to capture …

Groundwater exploration is the most promising way to overcome water scarcity in hyper-arid
regions around the world. Due to the scarcity of hydrogeological information in these …

Interactions between groundwater (GW) and surface water (SW) have important implications
for water quantity, water quality, and ecological health. The subsurface region proximal to …

We present a fast and efficient algorithm for simulation of a three-dimensional (3D) transient
electromagnetic (TEM) response using a modified shift-and-invert Krylov subspace method …

Subject to frequent channel avulsions due to the increased frequency of floods, rise of base
level, and/or sediment overloading, anastomosing rivers are sensitive to external (climatic or …

The structural depression that occupies the Okavango Basin in southern Africa comprises a
depo‐centre within the intracratonic Kalahari Basin where sediments of the Cenozoic …

Airborne electromagnetic (AEM) data can be inverted to recover models of the electrical
resistivity of the subsurface; these, in turn, can be transformed to obtain models of sediment …

Abstract The Okavango Delta of northern Botswana is one of the world's largest inland
deltas or megafans. To obtain information on the character of sediments and basement …

Fifty transient electromagnetic (TEM) and 15 audio-magnetotelluric (AMT) soundings were
carried out in the west central part of Portugal over an area of approximately 40 km 2 to …

Abstract The Okavango Delta in northern Botswana is an endorheic ecosystem formed by
150,000 islands surrounded by a flood plain. The vegetation of these islands displays an …
