WebMay 9, 2024 · The Nash–Sutcliffe model efficiency coefficient (NSE) is used to assess the predictive skill of hydrological models. It is defined as: N S E = 1 − ∑ t = 1 T ( Q o t − Q m t) 2 ∑ t = 1 T ( Q o t − Q ― o) 2 where Q ― o is the mean of observed discharges, and Q m is modeled discharge. Q o t is observed discharge at time t. [1] WebSep 23, 2024 · Moreover, NSE and the Kling-Gupta efficiency (KGE) are shown to be equivalent, at least when there are no biases, in the sense that they measure the relative magnitude of the power of noise to the power of variation of observations.
