Witryna3 lut 2016 · It depends on the context. For example, researchers at USGS feel 0.5 and above represents a good fit for streamflow conditions at a site in Minnesota.Also note that since the Nash–Sutcliffe efficiency coefficient is sensitive to extreme values (peak flow), it is important that you carefully consider any large outliers. http://www.nilim.go.jp/lab/rcg/newhp/history/pdf/setsumei.pdf

Models can be used for this purpose but require soil parameters at the field scale. This paper aims to estimate effective soil parameters by combining: (i) a surface flow-infiltration model, namely CALHY; (ii) an automatic fitting …
