1. Runoff:
* Surface runoff: This is the most common fate for water that doesn't percolate. It flows over the surface of the land, carrying sediment and pollutants, and eventually reaches a stream, river, lake, or ocean.
* Subsurface runoff: This occurs when water flows horizontally through the soil, but doesn't percolate deeply. It can also reach a stream, river, or lake.
2. Evaporation:
* Water can evaporate directly from the surface of the land, returning to the atmosphere. This is especially common in hot, dry climates.
3. Transpiration:
* Plants absorb water from the soil and release it into the atmosphere through their leaves. This is called transpiration.
4. Interception:
* Water can be intercepted by vegetation before it reaches the ground. Leaves and branches of trees and plants can hold water, which then evaporates.
5. Infiltration:
* Even if water doesn't percolate deeply, it can still infiltrate the soil to some extent. This can contribute to soil moisture and support plant growth.
The fate of water that doesn't percolate depends on several factors, including:
* Soil type: Sandy soils allow water to percolate easily, while clay soils are more resistant.
* Slope: Steeper slopes promote runoff, while gentler slopes allow more time for infiltration.
* Vegetation: Plants help to slow down runoff and promote infiltration.
* Climate: Rainfall intensity and frequency, as well as temperature and humidity, influence evaporation and transpiration.
It's important to note that the amount of water that percolates, runs off, evaporates, or is transpired can vary significantly depending on these factors.
