WebUnit Hydrograph Flow in cumec Flood hydrograph minus base flow is Direct Runoff Hydrograph (DRH). DRH is a consequence of rainfall excess of 6.23cm. UH, by definition, is a result of 1cm rainfall excess. Therefore, UH ordinates are derived here by dividing DRH ordinates by 6.23cm. Here, base flow is uniform all through flood hydrograph period. shower attachment for sink tapsWebhydrographs that may be added together, forming one irregularly shaped unit hydrograph.
