Students work in pairs on this worksheet in class after a short introductory lecture on how water reaches streams. Questions begin by addressing infiltration and the effect of surface runoff vs. groundwater flow on flooding. Students then progress to examine how humans change the amount of infiltration, and students must determine how the severity of floods can change as a result.
