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] find tfsa roomWebSep 2, 2024 · Two of the most widely used metrics are Nash-Sutcliffe efficiency ( NSE) and the Kling-Gupta efficiency ( KGE ).
