Mapping Soil Surface Macropores Using Infrared Thermography: An Exploratory Laboratory Study

Figure 2

Top view (photographs) of the flume soil surface showing macropores of different sizes scattered in accordance with the four scenarios described in the text: (a) Scenario A; (b) Scenario B; (c) Scenario C; and (d) Scenario D. The -axis represents the downslope distance along the length of the flume and the -axis represents the distance across the width of the flume (the dashed line defines the measuring area with 0.50 × 0.30 m²). See Figure 1.
