Solution Steps

Step 1: Analyze Graph 1

Graph 1 shows a longer, less intense peak in streamflow after the rainstorm. This suggests that water is being absorbed by the ground and slowly released into the stream over time.

Step 2: Analyze Graph 2

Graph 2 shows a shorter, more intense peak in streamflow. This indicates a rapid influx of water into the stream after the rainstorm, with less water absorbed by the surroundings.

Step 3: Match graphs with scenarios
  • Graph 1: "Abundant open farmland allows for infiltration of water into the ground" and "Flooding in a rural area" both describe scenarios where water is absorbed by the ground, leading to a slower rise in streamflow.
  • Graph 2: "Flooding in an urban area" and "Concrete surfaces mean water flows directly to the stream or river after a storm" and "This setting is more likely to produce flash floods" all describe scenarios with impermeable surfaces, leading to rapid runoff and a sharp rise in streamflow.

Final Answer:

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.
Step 2: Analyze Graph 1

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.

Step 3: Analyze Graph 2

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.

Step 4: Match Scenarios to Graphs
  • 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."
Final Answer
  • 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.
