According to the geomorphological instantaneous unit
hydrograph (GIUH) theory (Rigon et al.
Observed flood
hydrographs at Chashma and Taunsa are shown in Figure 1.
Although the annual
hydrograph of the Yukon River (Brabets et al., 2000) and fluvial processes affecting sediment regimes (Gordon et al., 2004) are subject to a degree of natural variability, the observed changes in the annual
hydrograph and sediment regimes may be linked to climate change in several ways.
[Q.sub.P]: Unit
hydrograph peak discharge for one millimeter of runoff (cubic meters per second)
The
hydrograph obtained using the model for the period 2006-2012 is compared to the measured
hydrograph in Figures 5-11.

Hydrograph and Partial Area Runoff Generation, Water Resour Res, 26(1), 1990, pp.
The first step in the process was to carry out the variogram analysis which describes the spatial structure among samples for each variable in each state of the
hydrograph. Based on the variogram parameters, in situ data was then spatially interpolated using the ordinary kriging method (Burrough and McDonnell, 1998).
The Santa Barbara Urban
Hydrograph (SBUH) methodology is common software used to estimate runoff generated from storm events.
A similar approach was used by Boughton (1985); however, our analysis uses a longer period of record, corrected catchment areas and
hydrograph interpretation.
Flood routing is the process of determining the time-varying flows, stages, and storage for the system in response to an inflow
hydrograph.
