Overview An excel file with the assignment data is provided on MyPlace. It is called CL935 Tutorial 3 Assignment Data. It contains daily river flow data for the years 1952-1955. This is real data from an upland catchment in Scotland (the River Tromie in the Spey catchment). The river is heavily modified with a hydro dam on the upper reaches. It is also home to wild Atlantic salmon which have a high economic value and are protected species. The BFI programme is also provided on MyPlace, you can use this to perform the hydrograph separation required for the analysis section. Using the data, prepare a report as outlined below. Report outline Report structure should follow this format: Introduction Methodology Analysis (Answer part A and B below) Discussion (follow discussion guidance below) Conclusion References Submission details Individual assignment each student to submit their own report. Submission of the Tutorial Exercise will be via MyPlace due on Friday 13th October2017 at 23:59 pm BST. Report should not exceed 1500 words, excluding title page, graphs, figures and references. PART A (manual exercise do not use BFI programme) 1. Using the assignment data provided, plot the river discharge on a graph (i.e discharge vs time) What months do the river flows appear highest? Why? 2. Adjust the primary horizontal axis to zoom into the time period 01/01/54 01/04/54 and indicate where you think the baseflow is. 3. Adjust the primary horizontal axis to zoom into the time period 01/11/54 - 01/02/55 and indicate where you think the baseflow is. 4. Of the above time periods (from 2 and 3), when do you think the river is less dependent on receiving water from baseflow? Why? PART B (use BFI programme) 5. Determine the BaseFlow Index of the assignment data using the BFI programme worksheet.
6 What is the BFI for each year? Would you consider this river to be highly dependent on groundwater? Indicate which year the Baseflow is more important for the aquatic life in the river and why? 6. Adjust the primary hortizontal axis to zoom into the time period 01/01/54 01/04/54 does this compare to where you indicated the baseline in Part A (2)? 7. Adjust the primary hortizontal axis to zoom into the time period 01/11/54 - 01/02/55 does this compare to where you indicated the baseline in Part A (3)? 8. Identify the rising limb, recession limb, peak, runoff, and base flow for either 6 or 7 Tip: Reduce the size of the series points in order to view the baseflow and discharge lines more clearly (Format data series points). Discussion General discussion: Do you think hydrograph separation is a valuable tool? Bas your answer on the analysis you have just carried out AND additionally make reference to one academic journal. Impact of assumptions: What assumptions has the method made? And what impact could this have?

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
