Answer 1

Explanation:

When rainfall intensity exceeds the infiltration capacity of the soil (as shown by the infiltration capacity curve), the soil cannot absorb all the incoming water.
The excess water then accumulates on the surface and starts flowing overland — this is known as surface runoff.

Additional InformationGroundwater Recharge

Occurs when water infiltrates through the soil and percolates down to the water table.
If infiltration capacity is already exceeded, no additional water goes to groundwater — it becomes runoff instead.

Evaporation

Evapotranspiration

Combination of evaporation and plant transpiration.
Like evaporation, it’s a gradual loss of water, not an immediate response to excess rainfall.
