1. Develop a rating curve for this stream at this section for use in estimating
the discharge for a known gauge reading and fit a linear regression
equation for use in estimation of stage for a known value of discharge. Use
a value of 9.375 as the gauge reading corresponding to zero discharge.
2. What is the coefficient of determination (R2) of the derived relationship?
3. Determine the stage for a discharge of 3500 cms.
4. Determine the discharge for a stage of 25 m.
