Circulation of Earth's Water supply.
A portion of the water sinks into the ground.
When earth can not absorb any more water the excess water turns into runoffs which run on the ground.
Infiltrated water that plants absorb and then release into the air.
Combination of evaporated water and transpired water.
Amount of water that runs off rather then sinking into the ground.
The land area that contributes to a river system.
Drainage basin of one stream is separated from another by an imaginary line.
Laminar Flow/Turbulent Flow
Laminar is very sow moving flow, and Turbulent flow is rapid and quick.
The slope of a stream channel expressed as the vertical drop of a stream over a specified distance.
The volume of water flowing past a certain point in a given time unit of time.
a solution brought to a stream by ground water.
Rivers carry most of the load suspension.
Material that is too large to be carried by suspension, they move along the bottom.
Speed as a particle falls through a still fluid.
Sediment appears to jump or skip across the stream bed.
Maximum size of particles it is capable of transporting.
Maximum load it can carry.
Solid particles of various sizes are separated.
Material deposited by a stream.
Streams that transport much of their load in suspension generally moving in sweeping bends.
Outside the meanders is a zone of active erosion.
Decreased zones of erosion.
New shorter segment.
The abandoned bend.
Channels that are interwoven.
A lower limit to how much a stream can erode.
Consists of not only of the channel but also the surrounding terrain that directly contributes water to the stream.
When a river overflows its bank during a flood.
Channels that flow in steep narrow valleys.
Channel deposits are most often composed of sand and gravel.
When a stream enters the relatively still waters of an ocean or lake, its velocity drops, abruptly.
Main channel dividing into smaller ones.
Built by successive floods over many years.
Areas behind levees are badly drained and the water cannot flow up the levee and into the river.
A tributary stream cannot enter a river because levees block the way often has to flow parallel to the river until it can breach the levee.
Typically develop where high-gradient stream leaves a narrow valley in mountainous terrain and comes out suddenly onto a broad flat plain or valley floor.
Forms where the underlying material is relatively uniform.
When streams diverge from a central area like spokes from the hub of a wheel.
Many right angle bends can be seen.
Drainage pattern, a rectangular pattern in which tributary streams are nearly parallel to one another and have an appearance of a garden trellis.
When the discharge of a stream becomes to large or to much it overflows onto its banks.
Zone Of Saturation
When the soil moisture prelocates downward until it hits a zone of open sediment filled with water.
The water within the Zone of Saturation.
The upper limit of the Zone of saturation
Area above the water table where the soil sediment and rock are not saturated.
Percentage of the total volume of rock sediment that consists of pore spaces.
Ability to transmit a fluid.
Impermeable layers that hinder or prevent water movement.
Permeable rock strata or sediments that transmit groundwater freely.
Water table intersecting the ground a natural flow of groundwater results.
The water temperature of the groundwater is 6-9 degrees hotter than the air.
Intermittent of hot springs which project water like a fountain.
A hole bored into the Zone of Saturation.
Whenever a substantial amount of water is withdrawn from a well the water table around the well is lowered.
Cone Of Depression
After a drawndown a depression in the water table is made and roughly a conical shape.
Applied to any situation in which groundwater rises in a well above the level where it was initially encountered.
Created erosion by groundwater.
Of the various dripstone features found in caverns.
Formations that develop on the floor of a cavern and reach upward toward the ceiling.
Landscaping dissolved and shaped by groundwater.
Karsts form sinkholes.. depressions in landscape.
