(2010b) first recognized a rising limb
of a minor positive excursion, which they named the ELKHORN excursion.
The hydrograph shape with a steep rising limb and concave recession limb is quite typical to vegetated small catchments.
The peak discharges increased higher in C3 than C1 after the removal of forest canopy as the hydrograph response also showed the faster response and shorter stormflow duration in C3 with sharp rising limb and recession compared with C1 with comparatively less steep rising limb and longer stormflow duration with the effect of forest canopy cover.
The rising limbs of the hydrographs for both catchments were very steep and the recession limbs depended on the rainfall intensity, especially during large storm events.
2004) while others reported that DOC typically peaked prior to the peak in discharge on the rising limb of the snowmelt hydrograph in forested mountainous catchments of Colorado (Hornberger et al.
Sampling intervals ranged from 5-10 h and were calculated based on historical discharge data to collect samples at a higher temporal resolution on the rising limb and peak of the hydrograph than the falling limb.
The time to peak is defined as the time between the start of the rising limb and the peak in discharge (Poor & McDonnell 2007).
For Storms 1 and 2, [Mg.sup.2+], [Cl.sup.-] and S[O.sub.4.sup.2] concentrations showed a quick decrease in concentration on the rising limb of the hydrograph with a progressive return to pre-event concentration levels on the falling limb of the hydrograph.
At the beginning of falling limb in ST-3 (time elapsed 60-70 minutes or between T60 - T70) the transport rate was 3.19 gr/s/m or more than 100 % higher from 1.58 gr/s/m observed during the similar level of discharge at the end of rising limb (time elapsed 50-60 minutes or between T50 - T60).
The transport rates measured at the same level of discharges during the falling limb were always higher than those in the rising limb. Overall, the average transport rate during 60 minutes of the rising limb (time elapsed T0 - T60) was 0.18 gr/s/m and this increased to 0.32 gr/s/m during the same period of falling limb (time elapsed T60 - T120).
These grains started to appear in transport at time elapsed 30 minutes of the rising limb (see Table 3).
The hydrograph's remaining vertices were connected to the origin of the rising limb
and a terminal point on the falling limb.
