(2019-07-15)Fluvial channel networks are observed to grow in unchannelized areas of low relief despite the low potential energy for erosion in these areas of low slope. Under these low slope conditions significant channel growth only ...
Linkages between fluid flow paths, reactive gases, and chemical weathering across a shale bedrock hillslope (2019-07-15)While the vadose zone is hypothesized to be an active region of solute generation, direct observations to verify this is lacking. Here, we report an integrated approach to characterize chemical weathering reactions in the ...
Uranium isotopes as indicators of uranium immobilization and remobilization in contaminated aquifer settings (2018-08-27)Tracking U immobilization through U(VI) reduction and mobilization induced by U(IV) oxidation using U concentrations alone is challenging, as groundwater transport, aquifer heterogeneity, and U(VI) adsorption can complicate ...
Archives of climate variability on Kiritimati: lacustrine, aeolian and remote sensing perspectives (2018-12-06)Sedimentary archives from tropical Pacific islands, together with records of modern hydrological processes, can provide information on past changes in tropical hydroclimate and test island landscape sensitivity to changes ...
Predition of compressive strength from point-load and moisture content indices of highly anisotropic, coal-bearing strata of the Illinois Basin (1983)
