Lesson 1: Introduction to Hydrogeology Flashcards
A colorless transparent, odorless tasteless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.
Water
Another nickname of the earth because
71% of the Earth’s surface is covered with water with an average of 3,500 meters depth
Blue planet
Percentage of fresh water supply around the globe
2.56%
Percentage of fresh water stored in glacial ice.
68.75% or 1.76%
Percentage of freshwater stored in groundwater and subsurface water.
30.07% or 0.77%
Percentage of fresh water stored in surface water, soil moisture, and atmosphere.
1.18%
Percentage of saline water around the globe.
97.44%
Percentage of saline groundwater around the globe.
0.94%
Study of occurrence, distribution, movement, and chemistry of all waters
Hydrology
Study of the interrelationship of geologic materials and processes with water.
Hydrogeology
An engineering field dealing with subsurface fluid hydrology.
Geohydrology
High amount of electrically charged atom or dissolved ions in the water.
Salinity
Low amount of charged atoms.
Freshwater
A precipitation that is temporarily stored as ice, snow, water puddles
Depression storage
Water that flows in the land surface to the gullies.
Overland flow
Water entering or seeping in the subsurface.
Infiltration
Soil pores contain both air and water.
Vadose Zone or Zone of aeration
It is located on the top of the vadose zone. Roots can even reach this zone.
Belt of Vadose Zone
Lateral flow of water in the vadose zone.
Interflow
Excess water in the vadose zone are pulled down by gravity.
Gravity drainage
It is the lowest point of vadose zone where water saturation approached by 100%.
Capillary Fringe
The top zone of saturation.
Water table
It is the water saturation zone. It seeps into rock and soil layer and discharge as a spring, lake, ocean, and river.
Groundwater
Water deep in the crust.
Magmatic water
