What is interception storage?
Interception Storage: The ability of vegetation surfaces to collect and retain Precipitation, capacity will be highest at the onset of rainfall when the vegetation is dry, when water is held by surface tension.
What is interception in water cycle?
In hydrologic sciences: Interception. When precipitation reaches the surface in vegetated areas, a certain percentage of it is retained on or intercepted by the vegetation. Rainfall that is not intercepted is referred to as throughfall.
Is interception a store or flow?
Stores include puddles, rivers, lakes (surface storage), glaciers, soil storage and groundwater storage along with water stored on vegetation (interception) following precipitation. Transfers or flows include percolation, overland flow, infiltration, stemflow, throughflow and overland flow.
How is interception storage measured?
Interception storage was calculated as the difference between the total water applied and the net water collected, correcting for water retained by the equipment. A graph of interception storage capacity (8) and the average height times percent cover of the grass showed little difference between the three species.
What is the difference between transpiration and interception?
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 geography GCSE?
This is known as precipitation . Stores: How water is stored or held for a period of time within the drainage basin system – interception (by vegetation), soil moisture, surface storage (lakes), groundwater.
How does interception affect the drainage basin?
Interception is another important factor controlling flows and stores within the drainage basin. It is basically when plants trap water or stop it from reaching the ground during a rainfall event.
What does interception look like?
An interception is when you have a house larger than 30 degrees AND it is engulfing an entire sign. A sign is totally enclosed in a house, and, as a result, they do not appear at the beginning of any house. An interception is NOT when you have two signs in one house–every chart has that naturally.
What affects interception?
Interception varies with the species, its age and density of stands. About 10 to 20% of precipitation occurring in the growing season is intercepted. It is lost substantially by way of evaporation from leaves. In dense tall vegetation interception is quite substantial.
What is interception loss?
Interception loss is that portion. of the precipitation which is returned to the. atmosphere through evaporation from plant. surfaces or is absorbed into the plant.
What is interception in geography?
Interception is the part of the rainfall that is intercepted by the earth’s surface and which subsequently evaporates. In this definition the earth’s surface includes everything that becomes wet after a rainfall event and that dries out soon after. It includes: vegetation, soil surface, litter, build-up surface, etc.
