Spatial Combination Modeling Framework of Saturation-Excess and Infiltration-Excess Runoff for Semihumid Watersheds

Figure 2

The spatial distribution of tension water capacity represented in XAJ model. is the tension water capacity at a certain point, is the maximum value of within a watershed, is the portion of the watershed area having tension water capacity smaller than , is the value of the vertical axis corresponding to , is the precipitation, is the runoff, is the antecedent soil moisture content prior to an event, and is the change in the soil moisture content.
