Upland Rootzone Soil Water Deficit Regulates Streamflow in a Catchment Dominated by North American Tallgrass Prairie

Autor: Andres Patrignani, Nathaniel Parker, Sofia Cominelli

Publikováno v: Water; Volume 14; Issue 5; Pages: 759

Intermittent tallgrass prairie streams depend on surface runoff and are highly susceptible to hydrological disturbances such as droughts. The objective of this study was to investigate the timing of intermittent streamflow pulses and upstream rootzon
