Hydrology part 1
What is the definition of stemflow?
The flow of intercepted water down the trunk or stem of a plant.
What is the definition of Aquifer?
A body of rock or sediment that stores groundwater.
Definition of phreatic zone?
Saturated zone below the water table.
What is the definition of river regime?
The seasonal variations in the discharge of a river.
What is the definition of Endorheic drainage basins?
Watersheds which do not drain to the sea.
What is the definition of lithosphere?
The rigid outer part of the Earth, consisting of the crust and upper mantle.
What is the definition of permeable?
(of a material or membrane) allowing liquids or gases to pass through it.
Definition of antecedent conditions?
Conditions prior to an event.
Definition of base level?
The lowest point to which a stream can erode
(usually sea level).
What is the definition of dendritic drainage pattern?
A stream system that resembles the pattern of a branching tree.
What is the definition of throughfall?
Water that reaches the ground either directly or after being intercepted by vegetation.
What is the definition of impermeable?
(of a material or membrane) not allowing liquids or gases to pass through it.
Definition of urbanisation?
The growth and expansion of urban areas.
Definition of open system?
A system in which matter can enter from or escape to the surroundings.
What is the definition of rectangular drainage pattern?
A drainage pattern characterized by numerous right angle bends that develops on jointed or fractured bedrock.
What is the definition of throughflow?
Water flowing through the soil layer parallel to the surface (this still moves downhill generally.
What is the definition of river discharge?
The volume of water which flows through a certain area at a given time. It is usually measured in cubic meters per second.
Definition of long profile (of a river)?
Shows gradient changes of a river over different courses.
Definition of closed system?
A system in which no matter is allowed to enter or leave.
What is the definition of radial drainage pattern?
A system of streams running all directions away from a central elevated structure, such as a volcano.
What is the definition of interception?
As precipitation approaches the surface, some of the rainfall will strike plant leaves, branches and other objects that protrude from the ground surface.
An abbreviation of cubic meters per second-which is a measure of the discharge of a river.
Definition of gradient?
A rate of inclination; a slope.
Definition of groundwater recharge?
A process by which water percolates through the soil and works its way into an aquifer.
What is the definition of trellised drainage pattern?
Tributaries join at high angles, often approaching right angles, which is common in areas with rocks of different strengths (resistance to erosion) and in areas with regular series of folds.
