What is the definition of Throughflow in geography?

What is the definition of Throughflow in geography? The movement diagonally downslope of water through the soil, as opposed to the vertical movement known as percolation. It may follow natural percolines in the soil. Throughflow is a major factor in the hydrology of a drainage basin where the rocks underlying the soil are impermeable.

What does Throughflow mean? In hydrology, throughflow, a subtype of interflow (percolation), is the lateral unsaturated flow of water in the soil zone, typically through a highly permeable geologic unit overlying a less permeable one. Throughflow usually occurs during peak hydrologic events (such as high precipitation).

What is percolation in geography? Percolation – the gravity flow of water within the soil. Stemflow – water running down a plant stem or tree trunk. Surface Runoff – the movement of water over the surface of the land, usually when the ground is saturated or frozen or when precipitation is too intense from infiltration to occur.

What does infiltration mean in geography? Infiltration – Water soaks or filters into the soil.
Surface runoff – Water moves across the surface of the earth becoming a stream, tributary or river.
Percolation – Water moving from the soil into the spaces (pores) in the rock.

What is the difference between Throughflow and groundwater flow?

Overland flow transfers water through the basin either as sheetwash, across the surface, or in tiny channels called rills. Beneath the surface, water is transferred via throughflow, which is the movement of water through the lower soil towards rivers, and groundwater flow. Groundwater flow is typically very slow.

What is the process of runoff?

Runoff occurs when there is more water than land can absorb. The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds. Glaciers, snow, and rain all contribute to this natural runoff. Runoff also occurs naturally as soil is eroded and carried to various bodies of water.

What is the definition of water table?

The water table is an underground boundary between the soil surface and the area where groundwater saturates spaces between sediments and cracks in rock.

What happens during percolation?

Infiltration and percolation

Do we drink groundwater?

Groundwater supplies drinking water for 51% of the total U.S. population and 99% of the rural population. Groundwater helps grow our food. 64% of groundwater is used for irrigation to grow crops. Groundwater is a source of recharge for lakes, rivers, and wetlands.

What is the start of a river called?

the source
The start of a river is called the source and the end is called the mouth. Many rivers and streams will join together before they reach the mouth of the river. The smaller rivers and streams are called tributaries.

What is an example of infiltration?

Infiltration is the process by which water on the ground surface enters the soil.
If the precipitation rate exceeds the infiltration rate, runoff will usually occur unless there is some physical barrier.
It is related to the saturated hydraulic conductivity of the near-surface soil.

What do u mean by infiltration?

1 : to cause (as a liquid) to permeate something by penetrating its pores or interstices infiltrate tissue with a local anesthetic. 2 : to pass into or through (a substance) by filtering or permeating. intransitive verb. : to enter, permeate, or pass through a substance or area.

What is the importance of infiltration?

Infiltration is extremely important, because it determines not only the amount of water that will enter a soil, but also the entrainment of the “passenger” chemicals (nutrients and pollutants) dissolved in it. FIGURE 13.1. Wet fronts for a sandy loam soil.

What causes Throughflow?

Throughflow is the sporadic horizontal flow of water within the soil layer (Figure 8m-1).
It normally takes place when the soil is completely saturated with water.
Water usually enters the surface sediments as precipitation.
This water then percolates into the soil layer.

What causes groundwater to flow?

Groundwater is transported through aquifers because of two main reasons: gravity and pressure. In unconfined aquifers, which we concentrate on because they are more likely to be contaminated, water always flows from high points to low points because of gravity.

What are the three main components of the water cycle?

The water cycle is often taught as a simple circular cycle of evaporation, condensation, and precipitation.

What are the 2 types of runoff?

Runoff may be classified according to speed of appearance after rainfall or melting snow as direct runoff or base runoff, and according to source as surface runoff, storm interflow, or groundwater runoff. 2. The sum of total discharges described in (1), above, during a specified period of time.

What is an example of a runoff?

Runoff is defined as excess water draining away from land or buildings. The overflow of water that drains off of your driveway is an example of runoff. Dissolved chemicals, etc, included in such water. The runoff of nitrates is poisoning the lake.

What is interflow runoff?

Interflow. Interflow, also known as subsurface runoff is relatively rapid flow toward the stream channel that occurs below the surface. It occurs more rapidly than baseflow, but typically more slowly than surface runoff.

What is the best definition of a water table?

Water table, also called groundwater table, upper level of an underground surface in which the soil or rocks are permanently saturated with water. The water table separates the groundwater zone that lies below it from the capillary fringe, or zone of aeration, that lies above it.
