What is interception and transpiration?
We conclude that interception mainly works as an intensifier of the local hydrological cycle during wet spells and wet seasons. On the other hand, transpiration remains active during dry spells and dry seasons and is transported over much larger distances downwind, where it can act as a significant source of moisture.
What is interception in plants?
Not all of the precipitation which falls to a watershed reaches the soil surface to become available for plant growth, stream flow, or groundwater recharge. Interception is the process by which falling precipitation interacts with the vegetation covering a watershed.
Is interception a store in the water cycle?
Water can also be temporarily stored via interception. This refers to the storage of water on leaf and plant stems. Dense foliage may result in little water reaching the ground, since it often evaporates from the leaves.
What is the rainfall interception?
Introduction. Rainfall interception is the fraction of rain that falls onto vegetation but never reaches the ground, instead evaporating from the wet canopy.
Which type of plants has the highest interception loss?
A different characteristic revealed in it is the issue of leaf area. The highest interception rate in cashew was 51.03 while in Pinus for example has highest interception rate of 76.66%. This reveals the effect of leaf area on interception loss per event.
What are the main components of interception?
Interception
- gross rainfall measured above the canopy or in openings in a forest.
- throughfall: water that falls between plants,
- drippage: of water from the plants to the grounds, and.
- stemflow: flow of water down stems and trunks.
What is infiltration How does it occur?
Infiltration occurs when surface water enters the soil. This process is similar to pouring water onto a sponge. The sponge soaks up the water until it can hold no more. At this point, the soil becomes saturated, but the excess water has to go somewhere.
What is the difference between infiltration and interception?
The highest level of interception occurs when it snows on conifer forests and hardwood forests that have not yet lost their leaves. Infiltration is the physical process involving movement of water through the boundary area where the atmosphere interfaces with the soil.
What is depression storage?
Depression storage refers to small low points in undulating terrain that can store precipitation that otherwise would become runoff. The precipitation stored in these depressions is then either removed through infiltration into the ground or by evaporation.
What is secondary interception?
secondary interception occurs in stratified forest communities where water drips from the canopy and is intercepted by lower plants.
What are the 3 main components of interception?
There are three Main Components of Interception:
- Interception Loss.
- Throughfall.
- Stemflow.
How is water intercepted in the water cycle?
The feedback you provide will help us show you more relevant content in the future. Interception, also known as canopy interception, is the process by which the precipitation is caught by the leaves and branches of trees and vegetation (the canopy). The volume of water caught by the canopy is referred to as interception.
What does interception mean in the hydrosphere?
THIS IS A DIRECTORY PAGE. Britannica does not currently have an article on this topic. In hydrosphere: Distribution of precipitation This process is termed interception and may result in little water reaching the ground because the water may be directly evaporated from plant surfaces back into the atmosphere.
Where does water interception occur in the forest?
Interception (water) It occurs in the canopy (i.e. canopy interception ), and in the forest floor or litter layer (i.e. forest floor interception ). Because of evaporation, interception of liquid water generally leads to loss of that precipitation for the drainage basin, except for cases such as fog interception,…
How much does interception affect the water balance?
Interception can amount up to 15-50% of precipitation, which is a significant part of the water balance. One can distinguish many types of interception, which can also interplay with each other. For example canopy, forest floor, fog, snow, and urban interception. This study we focus on canopy and forest floor interception.
