  • Webinar: Linked surface and subsurface modeling

    Surface flood modeling within urbanized areas has traditionally been performed using 1-D modeling techniques, i.e. HECRAS modeling for FIRM preparations. The recent implementation of 2D surface flow modeling has allowed urbanized areas to be modeled more accurately, but lack the subsurface drainage infrastructure interface. This presentation focuses on the current modeling practice of combining ...

  • Groundwater movement and contaminant transport in the Earth’s subsurface are the focus of two 2017 Darcy lectures

    Quantifying water movement and contaminant transport in the Earth’s subsurface are the critical issues addressed during presentations offered through the 2017 Henry Darcy Distinguished Lecture Series in Groundwater Science. Earth’s subsurface is part of the “critical zone” — the layer of the planet from the tops of the trees to the bottom of groundwater. This zone is ...

  • ASTM D5777 - 00(2011)e1 standard guide for using the seismic refraction method for subsurface investigation

    This guide summarizes the equipment, field procedures, and interpretation methods used for the determination of the depth, thickness and the seismic velocity of subsurface soil and rock or engineered materials, using the seismic refraction method. Measurement of subsurface conditions by the seismic refraction method requires a seismic energy source, trigger cable (or radio link), geophones, ...

The first of ...

  • Spatial variability in a waste rock pile

    One particularly interesting aspect of numerical modeling is accounting for spatial variability in an individual material property. In the numerical modeling of any subsurface model the aspect of spatial variability of material properties is often a concern. In general, quantifying sources of uncertainty has always been challenging. The list of potential aspects of introducing uncertainty into a ...

Headquartered in Santa Rosa, Calif., gINT Software has been a leader in geotechnical and geoenvironmental products since ...

  • Impacts of groundwater on local rainfall under a changing climate

    Climate change is expected to bring hotter conditions to many important agricultural regions. This will affect rates of evaporation from the ground and may also have an impact on local rainfall patterns. A recent study suggests that the depth of groundwater may determine the susceptibility of a region to drought following changes in temperature and rainfall. Understanding the transfer of water ...

  • Sophisticated monitoring array to address mystery of uranium plume

    Scientists have been puzzled for years about why uranium contamination in groundwater continues to exceed drinking water standards in an area located at the south end of the Hanford Site. The Department of Energy wants answers to why the uranium persists. Now, an innovative system has been installed for field experiments to better understand this complex site and to support future cleanup ...
