“…In recent years, comparative studies have also addressed the classification of vegetation biomes via water balance (Stephenson, 1990(Stephenson, , 2003, hydro-climatic controls on NDVI and transpiration (Thompson et al, 2011b;Voepel et al, 2011), controls on hydrologic regimes Olden et al, 2011;Sawicz et al, 2011), the relationship between available energy and soil development (Pelletier et al, 2013;Rasmussen, 2012;Rasmussen et al, 2011), the implications of different management regimes (Huntjens et al, 2011;Borowski et al, 2008) on water resources, and -in an initial sense -emergent patterns in human-hydrologic interactions (Srinivasan et al, 2012). Figure 5 illustrates three different relationships that emerge from 430 watersheds when considering patterns of hydro-climate (Budyko's curve), geomorphology (Abrahams curve) and vegetation cover (aridity -NDVI curve).…”
