Figure 3. Placement of measurements: (a) Schematic to show positions of marking rods and water content testing devices; (b) positioning rods and the marking string.
Figure 4. Development of slope failure with the rainfall process: (a) 3 min; (b) 10 min; (c) 19 min; (c) 23 min and (e) 30 min. Slopes were reinforced with large (left) and small (right) geocells.
Figure 5. Final appearance of the slope at the cease of rainfall under different rainfall intensities and slope ratios. Slopes were reinforced with large (left) and small (right) geocells.
Figure 6. Final appearance of the slope at the cease of rainfall. The left slope on the picture was reinforced using small geocell without wheat straw; the right model was the bare soil slope.
Figure 7. Development of soil erosion for small and large geocell reinforced slopes at different slope ratios: (a) 1:1.5 and (b) 1:2.0.
Figure 8. Slope displacement under different rainfall intensities and slope ratios.
Figure 9. Variation of the soil water content with time for (a) small and (b) large geocell reinforced slopes.
