Quizplus · Accepted Answer

A hydrograph plots the discharge (volume of water passing a point per unit time) on the y-axis and time on the x-axis. Therefore, the correct answer is C, which represents discharge vs. time. None of the other choices represent parameters commonly plotted in a hydrograph.
