groundwater transport Applications

  • Data analysis and visualization tools for groundwater and solute transport

    Groundwater and Solute Transport modeling is a sub discipline of environmental sciences with unique needs. Modeling has long utilized 3D simulations, but the ability to visualize and animate the results has lagged far behind the simulation technology. EVS-PRO, MVS, and EnterVol offer professional level presentation tools worthy of the current state-of-the-art in modeling. Visualization of groundwater and solute transport modeling results can be performed with all versions of C Tech’s software except for EVS for ArcView. EVS-Pro, MVS, and EnterVol are particularly well suited for animation and visualization of earth science modeling results from third party modeling systems such as USGS MODFLOW, MT3D, GMS©, Groundwater Vistas© and Visual MODFLOW©. Both combine animation capabilities with a powerful suite of visualization tools in a fully customizable environment.

Modeling has long utilized 3D simulations, but the ability to visualize the results has lagged far behind the simulation technology. EVS-PRO and MVS have long offered professional level presentation tools worthy of the current state-of-the-art in modeling, and EnterVol now opens that door to GIS professionals around the world. Visualization of groundwater and solute transport modeling results can be performed from third party modeling systems such as USGS MODFLOW, MT3D, GMS©, Groundwater Vistas and Visual MODFLOW© using C Tech’s tools to convert these modeling outputs into EFF format. In conjunction with Lawrence Livermore National Laboratory and IT Group, C Tech performed the visualization and animation of the output from a Groundwater Vistas MODFLOW and MT3D99 simulation of a large industrial complex in the central valley area of California.  This site exhibits highly channelized flow which is evidenced by the flow paths. Note that flow in the lower aquifer crosses underneath the upper channels at about 30 degrees!

  • Separation solutions for HDD / trenchless industry

    The HDD, trenchless and underground construction industry has realized the benefits and economics of recycling drilling fluid and slurry. With increased transportation costs and more stringent environmental enforcements and overall cost containment, the need for recycling is evident in all countries and across the range of trenchless applications. From maxi and mini HDD rigs to microtunneling and pipe jacking, packaged mud recycling units and mud reclaimers are an invaluable asset. The below diagram represents a closed loop zero discharge work site.

    Airport environmental protection solutions for the deicing / fuel containment

    Stabilization and Containment of Airport Fluids. Airports take careful measures to capture, contain, and treat deicing fluid and fuel runoff. In capturing the deicing fluid, the GEOWEB system stabilizes the pavement aggregate base layer and stores the deicing fluid in the contained aggregate voids. Stormwater containment basins built with impervious liners prevent infiltration of jet fuel and other contaminants into the groundwater. The GEOWEB system covers and protects geomembranes from puncture and solar degradation.

    Monitoring of fuels in stormwater

    The Situation

    A major pipeline company has large storage tank farms throughout the Western States. The pipeline company transports, stores, blends additives, and distributes gasoline, diesel, and jet fuel to retail service stations and airports. Due to the quantity and movement of fuel at these facilities, there is always the potential for fuel spills. These facilities prevent out of compliance discharge by capturing all stormwater in storm drains, which is then sent to treatment systems prior to discharge. At some sites, groundwater from ongoing remediation is mixed with stormwater at the treatment system prior to local discharge.

  • Distributed Temperature Sensing Technology for Stream Monitoring

    Temperature is an important factor in streams ecosystems. Heat tracers have been used to characterize contaminant transport, infiltration rates and energy exchange with groundwater, the atmosphere and radiation. The dynamics of these complicated water bodies is also affected by seasonal and diurnal patterns making characterization particularly challenging. Utilizing temperature measurements that capture spatial and temporal variations at stream ecosystem interfaces provides a mechanism for detailed characterization.
