Sentence examples for using the classical hydrograph from inspiring English sources

Twelve variables were separated using the classical hydrograph separation method.

and by using the classical inequality (7.23).

This method involves using the unit hydrograph of the US Army Corps Engineers (2000).

This model is based on the average unit hydrograph obtained from rainfall runoff data for small agricultural watersheds in the United States, and the unit hydrograph of the watershed is calculated through using the dimensionless hydrograph in TR-20 (Chow et al. 1988; Nourani et al. 2009).

The 1996 Arás basin flood was modelled using the unit hydrograph method, with most reliable results (217 m3 s−1) obtained using a semidistributed basin model.

Results obtained by using the geomorphologic unit hydrograph theory (GIUH) are also included for illustration purposes.

According to the results of the study done by Singh (1976), the derived unit hydrographs using the least squares method may not have a unit volume and some unit hydrographs ordinates may be negative.

Wooding (1965) determined the geomorphology-based runoff hydrograph using the kinematic wave theory for flow on a catchment and along the stream, assuming the rainfall of constant intensity and finite duration.

The results indicated that surface runoff hydrographs computed using the derived IUH equation were in satisfactory agreement with the observed hydrographs.

We assessed the performance using the Nash-Sutcliffe (NS), bias, mean monthly hydrograph and flow duration curve (FDC).

Further, DSRO hydrographs computed using the GGIUH model at two map scales (viz. 1 50,000 and 1 250,000) were found to yield comparable performance indicating suitability of using lower map scale to estimate the DSRO hydrographs.
