Laboratory Experiment and Numerical Analysis on the Precursory Hydraulic Process of Rainfall-Induced Slope Failure

Figure 9

Change in comprehensive water flow across boundaries (i.e., slope surface) over time. (a) Individual nodal flow. (b) Total runoff flow. The group of line plots are from the rainfall flux boundary nodes, whereas the group of “line and symbol” plots are from the seepage face boundary nodes (refer to Figure 5 for the two boundary section). On a color spectrum from blue to yellow, the darkest blue line indicates a node at the highest elevation, whereas the brightest yellow line indicates a node at the lowest elevation. The color spectrum is applied to the two groups of plots independently.
