What is a Percoline?

A hollow at the base of a hillslope where water (soil moisture) seeps out onto the ground surface and becomes overland flow. Also known as a seepage line. From: percoline in A Dictionary of Environment and Conservation »

What is the definition of 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 Throughflow mean in geography?

Beneath the surface, water is transferred via throughflow, which is the movement of water through the lower soil towards rivers, and groundwater flow.

What is soil water storage in geography?

Soil storage: water is stored around and between soil particles in what is called the pedosphere, or soil layer.

What is the output of a river system?

The final release of the water in a drainage basin is known as its output. Typically, rivers flowing into the sea will be the main output of a drainage basin. Some water will also be lost via evapotranspiration.

What is called percolation?

Percolation is the process of a liquid slowly passing through a filter. It’s how coffee is usually made. Percolation comes from the Latin word percolare, which means “to strain through.” Percolation happens when liquid is strained through a filter, like when someone makes coffee.

What is percolation in soil science?

Percolation in soil is simply the movement of the water through the soil and a soil percolation test is the means to measuring this movement. It is related to both saturation and water that drains away from roots too rapidly.

What’s the difference between throughflow and groundwater flow?

Rates of water movement via throughflow are usually low. Some of this water flows horizontally as throughflow. Water continuing to flow downward eventually reaches a permanent store of water known as the groundwater. The movement of groundwater horizontally is called groundwater flow.

What is Stemflow in geography?

Stemflow. the flow of intercepted water down the trunk or stem of a plant. Runoff/overland flow. the draining away of water from the surface of an area of land.

What is a store in geography?

It is a closed system, but made up of interlinked subsystems which are open and have inputs and outputs. It is made up of two main component: stores. function as sources (adding carbon to the atmosphere) and sinks (removing carbon from the atmosphere)

What is a drainage basin geography?

Drainage basins refer to the area of land drained by a major river and its tributaries. All rivers flow from the source (often in the mountains) to the mouth (the sea). The drainage basin is regarded as a closed system because water never leaves. Instead, it is recycled from one state to another.
