Dr. Trenton T. Cladouhos


B.S., Geology, Stanford University, Stanford, CA, 1988
Ph.D., Geological Sciences, Cornell University, Ithaca, NY, 1993.

Dr. Cladouhos is a Project Geologist in the FracMan Technology Group. Dr. Cladouhos has performed the discrete fracture data analysis, and fluid flow modeling for a diverse set of FracMan Projects. Projects he has worked on in the nuclear waste field include the North Carolina Low Level Nuclear Waste disposal facility, and Power Reactor and Nuclear Fuel Development Corporation (PNC, Japan) fracture flow modeling. In the oil industry, he has worked on the Fractured Reservoir Discrete Feature Network Technologies research project for BDM-Oklahoma and for various confidential clients.

Dr. Cladouhos is also an adjunct professor in the Department of Geology at the University of Washington. His research there, begun while a postdoctoral research associate, involves field and theoretical study of fault gouge and breccia from extremely well-exposed fault zones in Death Valley National Park, CA. Cladouhos has taught two courses at UW: Structural Geology (Spring 1996) and Geomechanics (Winter 1997). During the Spring 1998 quarter, he will be teaching a new course on Fractured Rock Hydrogeology, along with Golder colleagues Drs. Dershowitz, Doe, and La Pointe.

Dr. Cladouhos' fields of expertise include:

  • Field study of fractures, faults, and fault zones
  • Quantitative analysis of orientation, size, spatial structure, and flow/transport properties of fractured rock from core, borehole logs, and geologic mapping
  • FracMan discrete feature network (DFN) modeling and visualization
  • DFN flow/transport and modeling
  • Kinematic and dynamic analysis of fractures and faults
