How Does Runoff and Collection Work?

Rain falls on the ground, and runoff is like water flowing down a slide, it moves from high places to lower ones. When it rains, some water soaks into the soil, but not all of it, the rest runs off, just like when you spill juice on your table and it flows toward the edge.

Imagine you're playing with blocks in a puddle. If the ground is flat or sloped, the water will move along, gathering more water as it goes, this is collection. It’s like when you pour water into a cup from a pitcher; the water flows and gathers together.

Think of collection like a rain gutter on your house. When it rains, the water runs off the roof and goes down the gutter, collecting all that water in one place, just like how your bathtub fills up when you turn on the tap.

When runoff and collection work together, they help guide water to rivers, lakes, or even your backyard puddle!
