Water systems Flashcards
(30 cards)
A narrow pathway carved into sediment rock by the movement of surface water
Stream channel
Ground bordering each side of a stream that keeps the moving water confined
Stream bank
When a river or stream bed is diverted and the water flows down another channel
Stream capture
The elevation at which stream enters another stream or body of water
Base level
Curved or bend in a stream formed when a stream slope decreases water builds up into the stream channel and moving water roads away the sides of the stream bed
Meander
Triangular deposit usually made of soil and clay particles that forms where a stream enter enters a large body of water
Oxbow lake
A triangular shaped deposit of gravel sand and even smaller pieces of sediment such as silt
Alluvial fan
An area of a low flat land shaped like a triangle where a river splits and spread, spreads out into several branches before entering the sea
Delta
Process during which extreme resumes downcutting towards the base level increasing its rate of flow
Rejuvenation
Natural or human made body water that can form when a depression on land fills with water
Lake
Processed by which lakes become rich and nutrients from the surrounding watershed, resulting in a change in the kinds of organisms in the lake
Eutrophication
A low lying area of land that is saturated with water, either permanently or seasonally
Wetland
wet muddy ground too soft to support a heavy body
Bog
an area of low-lying, uncultivated ground where water collects
Swamp
a type of wetland, an area of land where water covers ground for long periods of time
March
Aver. Width (m) X aver. Depth (m) X aver. Velocity (m/s)
Discharge formula:
The discharge of sediment particles which are too heavy to be held up by the turbulent action of the flow
Bed load
The measure of the volume of stream water that flows past a particular location within a given period of time
Discharge
An elevated land area that separates one watershed from another
Divide
Potentially devastating natural occurrence in which water spills over the sides of a stream banks onto adjacent land areas
Flood
An area of low laying ground adjacent into a river formed, mainly of river, sediments, and subject to flooding
Floodplain
All of the waters on earth surface
Hydrosphere
Water flowing down slope along earth surface
Runoff
The method of transport for all particles small enough to be held up by the turbulence of a streams moving water
Suspension
