Here's the thing:
The diagram clearly shows that as urbanization increases, so does the amount of runoff. This makes sense because when natural land is replaced with impervious surfaces like parking lots and buildings, the water can't soak into the ground as easily. Instead, it runs off into streams and rivers.
So, the relationship between runoff and land development is a **direct** one. The more land that's developed, the more runoff you'll see.
