Environment Assignment

Question : Basic Streamgauge Data

• Provide a table of the basic gauge information
• Provide a photograph of the control weir
•  Provide an image showing the creek cross section at the streamgauge
•  Provide an image of the rating curve and answer the gauging questions.
• Make a comment of the adequacy of the rating curve based on this information.

Missing Data

•  Provide a monthly discharge timeseries plot and state the % of missing data

Annual Series Analysis

•  Provide a table of the water years in chronological order with the peak discharge for each year and the number of months of missing data for each year. Highlight the water years when the amount of missing data is unacceptable. 10 marks
• Table the Annual Series discharges, ranked in order. State the number of water years (N) included in the Annual Series, allowing for missing data.
• Tabulate the Annual Series statistics (mean and standard deviation of log(discharges) and skew) for both cases of with and without the lowest 9 floods.

Partial Series Analysis  

•  State the number of floods (K) included in Partial Series and the corresponding discharge threshold.
•  Table the Partial Series discharges, ranked in order. Show the rank, the month and the peak discharge.
• Provide a regression plot with fitted equation. Report the floods that were excluded from the regression.
• Provide a Partial Series frequency chart
• Report the design discharge estimates for the specified ARIs

RFFE design discharge estimates

•  Provide a catchment plan showing the catchment boundary and centroid for Emu Creek upstream of the streamgauge
•  State the key information to use RFFE, including the centroid and streamgauge coordinates, and catchment area.
• Table the RFFE design discharge estimates for the specified ARIs
