Figure 1: Maps of the (a) location of the study region, (b) digital elevation model, (c) soil type, and (d) land use land cover.
Figure 2: Schematic illustration of the re-infiltration scheme.
Figure 3. Parameter sensitivity with metrics indicated in Table 2.
Figure 4: Map of binary flood detection comparison. FP: False Positives; FN: False Negatives; TP: True Positives.
Figure 5: Spatial distribution of differences of (a) maximum depth, (b) initial inundation timings, and (c) inundation durations along with respective sample distributions (red line represents the mean value of the distribution). Temporal evolution of (d) soil moisture (%) and (e) surface water volume. The difference of surface water volume in (e) is plotted in the shaded area.
Figure 6: Simulated and observed time series of surface water height at five USGS stream gauges.
Figure 7: Maps of maximum surface water depth for (a) on re-infiltration and (b) off re-infiltration with differences against High Water Marks (HWMs). (c) histogram of water depth difference. Maps of two examples, (d) and (e), with the difference larger than 1 meter between the simulation and USGS HWMs.
Figure 8: Basin aggregated distribution of (a) maximum depth differences, (b) initial inundation timing differences, and (c) inundation duration differences. Time series of basin-average (a) soil moisture and (b) surface water volume. The vertical dashed line indicates the mean value of all samples.
