Catch meant area
The drainage area that supplies water to the river
Drainage Basin
Area drained by a river system
Source
Place where’s a river begins
Mouth
Where the river flows into a sea or lake
Surface runoff
Rainwater flowing over the surface
Watershed
High ground separating one drainage basin from adjacent drainage basin
Stream or river network
Single streams and rivers that are connected
Tributaries
Single river channel forming the stream network
Confluence
Point where one river in the network joins another
Interfluves
Ridges of high ground between individual channels
Overland flow
Rainwater flowing over the surface
Channel flow
Water flowing in a river channel
Throughflow
Water flowing through the soil
Permeable rocks
Rocks that allow water to seep in
Groundwater
Underground water
Groundwater flow
Water flowing through underground rocks
Impermeable rock
Rock without pore spaces or cracks through which water is able to pass
Water table
Upper surface of the groundwater
Base flow
Groundwater that seeps into a river
Geology
Rock structure
Topography
Relief
Radial pattern
Develops on a fine where streams flow outwards and downhill
Trellis pattern
Forms on inclines strata that are unequal resistant to erosion
Strata
Rock layers
