WebbBaseflow is a component of streamflow composed of the delayed storage release of groundwater but also can include surface water sources such as lakes, wetlands, and snow and ice melt (Smakhtin, 2001). Webbbaseflow conditions provides valuable insights into changes in water sources, being especially important for the development of catchment management strategies, especially in light of future drought scenarios (Peralta-Tapia et al., 2015; Smakhtin, 2001).
