Seawater intrusion and fresh groundwater hydraulics in fjord delta aquifers inferred from ground penetrating radar and resistivity profiles—Sunndalsøra and Esebotn, western Norway

A review of groundwater sustainability crisis in the Pacific Island countries: Challenges and solutions

“…(e) Pumping of saline groundwater will increase the water volume and reduce the chance of SWI in the groundwater. This technique reduces the volume of saline water underground and protects abstraction wells from upconing (Soldal et al, 1994;Sherif and Hamza, 2001;Barrett et al, 2002;Rastogi et al, 2004). (f) Forming groundwater circulation well, allows a vertical circulation flow by pumping groundwater from the aquifers through a screen in a single well and injecting back into the aquifer through different screen.…”

Comparative soft‐tissue preservation in Holocene‐age capelin concretions

“…Work by Desaulniers and Cherry (1989a) has shown that sediments in the Ottawa Valley immediately adjacent to Greens Creek are composed of marine clays with measured porewater velocities (i.e., 2 m/ year) on-par with (modeled) stagnant, diffusion-limited, concretion formation (Berner, 1968a). On the other hand, while velocities are not available from Kangerlussuaq, measurements of analogous glacial deposits from Norwegian fjords estimate an excess of 100 m/ year (Soldal et al, 1994;Soldal & Rye, 1995). These observations suggest organic matter input, decay rates, and post-depositional properties are parameters, which greatly influence the rate of concretion formation.…”

Four‐dimensional electrical conductivity monitoring of stage‐driven river water intrusion: Accounting for water table effects using a transient mesh boundary and conditional inversion constraints

“…Characterizing the spatial and temporal extent of GW‐SW mixing within an aquifer using well‐based data alone is challenging when wellbore locations are sparsely distributed. Several researchers have recently demonstrated the utility of time‐lapse ERT for remotely monitoring changes in the pore water chemistry of aquifer sediments in GW‐SW systems [ Befus et al ., ; Cardenas and Markowski , ; Cardenas et al ., ; Coscia et al ., ; Coscia et al ., ; Coscia et al ., ; Dimova et al ., ; Doetsch et al ., ; Henderson et al ., ; Johnson et al ., ; Meyerhoff et al ., ; Slater et al ., ; Soldal et al ., ; Toran et al ., ; Wallin et al ., ; Ward et al ., ; Zarroca et al ., ].
