Question 1: the graphic below (from zhang and guilebert, 2016) depicts a dendritic stream network (a) print out and highlight (with one colour per stream order) or label all streams of order 2 or higher in the diagram. what is the stream order of the outflow of the stream network? during the winter months, this stream network is dry, but when the winter comes, water fills each of the channels. (b) if the highest order stream has a discharge of 5 m3 s-1 in this flood season, as measured by a weir, and is observed to be 500 m across with a drop of 1 m for every 100 m of length along the river, what kind of bed-forms do you expect to see once the stream is dry again the next summer if the grain size is 0.1 mm?
