Data Analysis assignment—physical template in streamsStream EcologySpring term 2015Name ______________________________________________The River Lively is located in the continental United States. A geomorphic study was donerecently to describe the geomorphology and flood-plain vegetation. Some of the data that werecollected are presented here. Please use the figures and photos to answer the followingquestions for two valley segments—A and B. Be as clear and concise as possible.1.How would you classify each of these valley segments—A and B? Use theclassification system that was presented in class and define the criteria you use, basedon the data that are provided. Why do you think it is useful to classify valley segments?2. How do the selected reaches compare in terms of the extent of lateral channel migrationand secondary and/or backwater channels? What are the key valley characteristics thatseem to be associated with the development of these channel types?3. Just looking at the hydrograph from water year 1935, how would you characterize theflow regime in this river? What additional insight do you gain in looking at thehydrograph for water year 1965? Do you see any evidence of the 1965 peak-flow eventin the subsequent channel conditions, looking at the plots that show characteristics fordifferent time periods? What processes do you suppose might have been enhanced?4. Floodplain deposition requires floodplain inundation. The frequency of floodplaininundation may be decreasing in the River Lively due to channel incision and leveeconstruction. Would you expect downstream sediment loads in the river to increase ordecrease as a result? Why?
