What is a reasonable interpretation for the flow event recorded by this hydrograph? 
A)there were two pulses of runoff because there were two storms 
B)the drainage basin has several distinct parts 
C)one pulse could be due to snowmelt and the other to rain 
D)all of these

Quizplus · Accepted Answer

The hydrograph shows two distinct pulses of runoff, which could be due to two separate storms or due to a combination of snowmelt and rainfall. The fact that the second pulse continues at a lower magnitude for a longer period of time suggests that the drainage basin has several distinct parts with varying runoff characteristics. Therefore, all of the given options are reasonable interpretations for the flow event recorded by this hydrograph.
