Graph 1: Abundant open farmland allows for infiltration of water into the ground, Flooding in a rural area
Graph 2: Flooding in an urban area,### Step 1: Understand the Problem
The task is to label each graph with the scenario it most likely represents. The graphs show the relationship between rainfall and streamflow over time. The scenarios to choose from are:
- Abundant open farmland allows for infiltration of water into the ground.
- Flooding in an urban area.
- This setting is more likely to produce flash floods.
- Concrete surfaces mean water flows to the stream over a short time.
Graph 1 shows a sharp increase in streamflow immediately after the rainfall, followed by a rapid decrease. This indicates that the water quickly reaches the stream and then rapidly decreases, which is typical in urban areas with concrete surfaces where water cannot infiltrate the ground.
Graph 2 shows a more gradual increase and decrease in streamflow, indicating that the water infiltrates the ground before reaching the stream. This is typical in areas with abundant open farmland where water can infiltrate the ground.
- Graph 1: "Flooding in an urban area" and "Concrete surfaces mean water flows to the stream over a short time."
- Graph 2: "Abundant open farmland allows for infiltration of water into the ground."
- Graph 1: Flooding in an urban area, Concrete surfaces mean water flows to the stream over a short time.
- Graph 2: Abundant open farmland allows for infiltration of water into the ground.
