13.6 Problem Set
- The thermal diffusivity for a particular soil is 0.43 x 10-6 m2 s-1.
- What is the damping depth for the diurnal temperature wave?
- What is the damping depth for the annual temperature wave?
- At what depth is the amplitude of the annual temperature wave only 5% of the amplitude of the annual wave at the surface?
- What is the time lag (hr) between the occurrence of the daily maximum temperature at the surface and at 30-cm depth?
