39. Students simulate precipitation on the surface of the “developed” undergroundwater model. What happens to the rainwater that falls on buildings and roads?
104. Trail Point #6: Human Impact on River Basin Productivity At the “eroding bend” location, students will observe and discuss the ways humans have changed and developed the land. Analyze the absorbent and non-absorbent features of the area. What are the implications of resurfaced areas on the groundwater system? What are the consequences for habitats and the organisms that live there? Without sufficient absorbent features, runoff and flooding will cause erosion, and the groundwater system will not store enough water to replenish habitats. Experience the Concept on the Trail
