Figure 7 Scatter plots of the first derivative of hourly temperature with time (dT/dt) against the second derivative of hourly temperature with depth (d2T/dz2). The total debris thickness of debris was 0.38 m for the monsoon season and 0.40 m for the winter season at the AWS site. The time period for the assessment of the derivatives: September 24 to October 3 2013 for (a) monsoon, and December 1 to 4 2013 for (b) winter. The slope of the best fitting line gives an approximation of the thermal diffusivity
