Stream habitat assessment along a transect
July 29, 2016

Stream habitat assessment along a transect

Stream habitat data is collected along a series of transects marked by tape measure and includes estimating rock size categories (for example, sand, gravel, cobble, boulders) with a guide (shown).

Bank height above water surface assessment
July 28, 2016

Bank height above water surface assessment

Bank height above the water surface is measured at each transect along a stream reach to estimate the channel and bed substrate as well as the type and size of sediment size that can be transported by the stream.
