  1. Mechanical Energy Field • All short term processes • Ignore influence of the Environment Load, Deformation, Velocity, Weight, Mass, Wave, Sound Foundation design Governing Laws Flow through porous media Acid rains • Darcy’s Toxic/Hazardous wastes • Hook’s Nuclear waste storage/containment • Newton’s Land slides • Law of motion Earthquakes

  2. Thermal Energy Field • Includes the influence of the Environment Hydration, Heat of Wetting, Heat of Contact, Heat of sublimation, Thermo-osmosis Freeze-thaw Governing Laws Wetting-drying cycle Fire in mines/underground • Gas law Thermal/ Desiccation cracks • Fourier’s law • Laws of Thermodynamics

  3. Basic characteristics of Thermal Energy Field Additional forces are produced when water is added to dry or partially saturated soils ---Environmental forces/stresses Heat transfer due to thermal field affects soil-water-air behavior State of matter, existing in the thermal energy field, changes as a function of change in temperature Liquid to Gas (Heat of Vaporization) Liquid to Solid (Heat of Fusion) Solid to Gas (Heat of Sublimation) Depends upon Energy input/release

  4. Electrical Energy Field • Includes the influence of the Environment Polarization, Electromotive force, Electrical conductivity Creep Viscosity Governing Laws Stress hardening & softening Aging effect • Coulomb's law Contaminant Migration • Joule’s law Site-remediation • Ohm’s laws Electro-kinetics • Ampere’s law Electro-osmosis

  5. Magnetic Energy Field • Includes the influence of the Environment Electromagnet, Ferro-magnet, Electromagnetic induction, Electromagnetic waves FDR/TDR probes Governing Laws For soil mass characterization Volumetric moisture content • Faraday's law • Lenz’s law • Bio- savart’s law • Gauss’s law

  6. Applications of Electromagnetic Field Various disciplines. X-rays are high frequency electromagnetic radiations and are used in radio astronomy, radiography in medicine and radiometry in tele-communications Laser therapy, which is an example of photo-medicine. Applications of Lasers: Laser-guided bombs Barcode readers Laser therapy

  7. Radiation Energy Field • Includes the influence of the Environment Decay process, Radioactivity, Nuclear reaction Governing Laws • Nuclear physics • Atomic physics
