Part (I) of this study presented field and laboratory experimental data on soil characteristics and hydraulic parameters that are related to water infiltration in rice paddy fields. Part (II) includes a series of numerical simulations that are based on the in situ data, which three-dimensional finite element computer model for simulating density dependent flow and transport (FEMWATER) produced ...

Groundwater models are being constructed to evaluate the impact of increased development on two adjacent sandy barrier islands on the northern Gulf coast of Florida, USA. To characterize the hydrostratigraphy and seasonal variability we are conducting resistivity and electromagnetic profiles across the freshwater lens and seepage meter and well sampling of freshwater fluxes and heads. The islan...

UNLABELLED Marine methane seeps are globally distributed geologic features in which reduced fluids, including methane, are advected upward from the subsurface. As a result of alkalinity generation during sulfate-coupled methane oxidation, authigenic carbonates form slabs, nodules, and extensive pavements. These carbonates shape the landscape within methane seeps, persist long after methane flux...
