1
Q
What are storm hydrographs?
A
show river discharge around the time of storm event, only covering a short period of time.
2
Q
What is peak discharge?
A
the highest point on the graph, when river discharge is greatest
3
Q
What is lag time?
A
delay between peak rainfall and peak discharge
4
Q
What is rising limb?
A
part of the graph up to peak discharge. Increase in river discharge
5
Q
What is falling limb?
A
part of the graph after peak discharge. Decrease in river discharge
