WebStep IV – Corresponding to unit depth of the unit hydrograph (i.e. 1 cm), the ordinates of the runoff hydrograph are linearly interpolated to obtain the unit hydrograph ordinates. The unit hydrograph ordinates are plotted on a graph. The next step is to work out the ‘unit duration’ of this unit hydrograph by analyzing the storm rainfall data. WebDec 1, 2015 · It is observed that the CWC unit hydrograph (UH) underestimates the peak discharges both for catchments smaller than 200 km2 with steeper slope and larger than 600 km2 with flatter slope. いらすとや 女性社員 https://pferde-erholungszentrum.com
