True or False? Stream discharge is defined as the quantity of water flowing past a specific channel location per unit time.
True
True or False? For the same discharge, gradient, and channel cross-section, a stream with a boulder-strewn bed would be more turbulent than one with a sandy bed
True
True or False? Alluvium refers to stream deposits, mainly sand and gravel.
True
True or False? The lowest base level for most streams is lake level.
False
True or False? A stream flowing out from a lake cannot downcut below the water surface elevation of the lake.
False
Match each stream drainage pattern below with an appropriate name for it.
