What do we mean by Surface-runoff?

Edu-fact: Using an instrument called an infiltrometer, the research team examined differences in water infiltration rates between sites that had many cicada emergence holes and nearby sites with few holes in central Indiana – one of the hotspots of Brood X emergence.
Infiltration is the process of water entry into the soil through the earth's surface.
