An extensive geophysical tool box is available with which to construct models of subsurface flow paths in complex aquifers using a combination of surface and borehole methods. These methods include electromagnetic and seismic sounding from the surfac

A simple mass-balance code allows effective modeling of conventional fluid column resistivity logs in dilution tests involving column replacement with either distilled water or dilute brine. Modeling a series of column profiles where the inflowing fo

A survey of Ozark chinquapin in northwest Arkansas showed the tree to be widespread but uncommon, locally concentrated on sandstone benches and upper slopes in karst terrain. The remains of pre-blight chinquapin trees were mapped and measured on two

Aim Chestnuts (Castanea spp.) are ecologically and economically important species. We studied the general biology, distribution and climatic limits of seven chestnut species from around the world. We provided climatic matching of Asiatic species to N

Application of the cross-borehole flow method, in which short pumping cycles in one borehole are used to induce time-transient flow in another borehole, demonstrated that a simple hydraulic model can characterize the fracture connections in the bedro

The Potsdam Sandstone of Cambrian age forms a transboundary aquifer that extends across northern New York and into southern Quebec. The Potsdam Sandstone is a gently dipping sequence of arkose, subarkose, and orthoquartzite that unconformably overlie

High-resolution flowmeter measurements such as those obtained with heat-pulse and electromagnetic flowmeters are often analyzed to produce in situ permeability profiles of heterogeneous aquifers. However, the borehole environment exerts a strong infl

Aim The character and distribution of American chestnut (Castanea dentata) populations in New England are analysed to identify the extent to which the introduced chestnut blight and historic land use practices have affected chestnut distribution and
