WebbBaseﬂow was derived from daily streamﬂow records with a recursive digital ﬁlter method. The results showed that baseﬂow varied between 38 and 80% (0 and 331 mm/year) of total streamﬂow with an average of 60%, indicating that more than half of streamﬂow in the MORB is derived from baseﬂow.

Baseflow Separation – A Practical Approach

Webb5 nov. 2013 · The catchment-scale estimation of the base flow characteristics demonstrated encouraging performance with R2 values of 0.82 for BFI and 0.72 for k. The connection weights of the trained ANNs indicated that climatic characteristics were more important for estimating k than BFI. 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).
