A sub-catchment stream is a smaller water body that drains a specific area, contributing to a larger watershed or catchment. It collects runoff from rainfall, snowmelt, and other sources, channeling this water into larger rivers or lakes. These streams play a crucial role in the hydrological cycle, supporting local ecosystems and influencing water quality within the larger catchment area. Understanding sub-catchment streams is essential for effective water management and conservation efforts.
The stream's catchment.
A drainage basin/ watershed.
The land area that contributes water to a stream is known as its watershed or catchment area. This area collects rainfall and other sources of water, which then flow into the stream through surface runoff or groundwater discharge. The health and size of the watershed can significantly impact the quantity and quality of water in the stream.

Reservoirs which collect the rainwater that falls in the catchment areas.
The catchment or drainae basin is all the land from the mountain to to seashore, drained by a single river and its tributaries is called catchment area or drainage basin
Basin Or Watershed
Brisbane is located in more than one catchment, and within Brisbane are several catchment areas. Most of the Brisbane River is in the Brisbane Valley catchment. Refer to the related link below for more detail of the various catchments.
No not every river IS a catchement. Although, yes every river does have a catchment area. The catchment area is the surrounding land within a watershed in which a single river system drains.

Flow velocity..answer 2 Sometimes the rock type in a stream basin is not uniform. e,g, there could be a volcanic sill in the catchment. In this case, the harder volcanic material could cut through the bed material much faster than if it were uniform.
