At Lindsey Road? May 1" 2016 b) Why is there a difference in the discharge at the two locations? c) What impacts do humans have on the amount and rate of runoll? Removing . of vegetation and soit,grading the land Surface and constructing drainage networks increase Yun off wormes 5) The gage height and discharge of Fourche Creek at University Ave, which was measured by the USGS, are listed on Table 8.1. Rank the data in order from highest to lowest peak stage. Assign cach measured point a ranking, called the magnitude number (M). The highest stage (gage height) is given a magnitude number of 1, and lower stages are numbered in increasing M for the duration of the record.
