  • Impact of Dam Operations on Hyporheic Exchange in Riparian Zone of Regulated River

    Abstract: Dam operations commonly cause large, frequent fluctuations in river stage, which persist for long distances downstream. The stage fluctuations force river water into and out of the hanks, defining lateral hyporheic exchange paths. To evaluate the penetration distance and rates ot dam-induced hyporheic exchange, we monitored water-table elevation, temperature. and specific ...

  • In Situ Thermal Treatment for Soil, Sediment, and Sludge

    The main advantage of in situ thermal treatment is that it allows soil to be treated without being excavated and transported, resulting in significant cost savings. However, in situ treatment generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in soil and aquifer characteristics and because the efficacy of the process is ...

  • Extraterrestrial hydrogeology

    Subsurface water processes are common for planetary bodies in the solar system and are highly probable for exoplanets (planets outside the solar system). For many solar system objects, the subsurface water exists as ice. For Earth and Mars, subsurface saturated zones have occurred throughout their planetary histories. Earth is mostly clement with the recharge of most groundwater reservoirs from ...

  • In Situ Biological Treatment for Ground Water, Surface Water, and Leachate

    The main advantage of in situ treatment is that it allows ground water to be treated without being brought to the surface, resulting in significant cost savings. In situ treatment, however, generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in aquifer characteristics and because the efficacy of the process is more ...

  • Water Cycle

    The sun, which drives the water cycle, heats water in oceans and seas. Water evaporates as water vapor into the air. Ice and snow can sublimate directly into water vapor. Evapotranspiration is water transpired from plants and evaporated from the soil. Rising air currents take the vapor up into the atmosphere where cooler temperatures cause it to condense into clouds. Air currents move water vapor ...

  • Properties and Behavior of Halogenated SVOCs

    An important consideration when evaluating a remedy is whether the compound is halogenated or nonhalogenated. A halogenated compound is one onto which a halogen ion(e.g., fluorine, chlorine, bromine, or iodine) has been attached. The nature of the halogen bond and the halogen itself can significantly affect performance of a technology or require more extensive treatment than for nonhalogenated ...

  • Dynamics of Hyporheic Flow and Heat Transport Across a Bed-to-Bank Continuum in Large Regulated River

    [i] The lower Colorado River (LCR) near Austin, Texas is heavily regulated for hydropowcr generation. Daily water releases from a dam located 23 km upstream of our study site in the LCR caused the stage to fluctuate by more than 1.5 m about a mean depth of 1.3 m. As a result, the river switches from gaining to losing over a dam storage-release cycle, driving exchange between river water and ...
