Correlation of site volume and local resources. (A) Modeled surface drainage and sites in the hinterland of Tell Beydar (compare with streams shown in Fig. 1). (B) Log-linear relation between Strahler value and catchments area (boxes indicate quartiles, black line the median). (C) Relation between settlement density and soil type; box plots show the distribution of observed volumes for different soils (y axis), ranked with respect to the total area of the specific soil region (x axis). (D) Relation of settlement density with water availability; shown are median (lines) and quartiles (shaded areas). Units are normalized for visualization purposes.
