Darcy's Law is one of the most essential concepts in hydrogeology. Before moving on to more complex problems, students must first thoroughly understand the basic principles of one-dimensional fluid flow through saturated porous media that are embodied in Darcy’s Law. We believe that the best way for students to learn these principles is through experimentation. In this paper, we introduce an ex...

Darcy’s Law is the fundamental equation describing the flow of fluid through porous media including groundwater. It forms the quantitative basis of many science and engineering disciplines including hydrology, hydrogeology, soil science, civil engineering, petroleum engineering and chemical engineering. The year 2006 marked the 150th anniversary of the publication of Henry Darcy’s most famous t...

Heterogeneous granular sediments—sands and gravels —form the most important water-supply aquifers in many areas of North America. In the past 60 years many such aquifers have become contaminated with nonaqueous phase liquids (NAPLs) and the dissolved phases associated with them. These include glacial outwash deposits in New England, Ohio, and Ontario, the floodplain alluvium along the Columbia ...

Geothermal projects in the Upper Rhine Graben aim to harness thermal anomalies that have arisen due to hydrothermal circulation within the granitic basement and the overlying Permo-Triassic sedimentary units. We present here a systematic microstructural, mineralogical, and petrophysical characterisation of the lowermost unit of this Permo-Triassic sedimentary succession—the Buntsandstein—sample...

Water and contaminants obviously do move through the so-called impermeable glacial tills in Ohio. This study was conducted to illustrate the extensive presence of fractures in the till and to quantify the differences in hydraulic conductivity and physical and chemical properties between the fractureaffected zones and the till matrix. In situ measurements of the saturated hydraulic conductivity ...

Geometry of the pore space is a fundamental control on flow in carbonates over reservoir exploitation time scales. Fluid properties and pressure gradients are temporally variable and can be changed by use of effective reservoir production, workover, and stimulation procedures. The geometry of the porous medium largely remains constant except if significant pressure variations deform or fracture...

There is enormous global interest in forest restoration, with governments around the world making high profile and ambitious commitments (Fagan et al., 2020). Carbon sequestration an important driver of this policy interest, but it widely recognized that restoration needs to be considered as part a landscape approach which aims improve both ecological functioning livelihoods local people (Chazd...
