Perform a complete series analysis on the Athi River data in Table $4.$Determine the mean monthly discharge. If the average demand for Konza Citysupply is $0\mathrm{.}25$ m$3/$s$,$ and the regulatory agency will permit a withdrawal of $5\%$of the flow, will the Athi River provide a safe yield?

b$.)$ In continuing the evaluation of the athi river as a water supply for Konza city above perform an annual minimal extreme value analysis on the data in table $4.$ Determine the recurrence interval of monthly flow that fails to meet an average demand of $0\mathrm{.}31$ m$3/$s$.$ Also determine the discharge of the mean monthly annual minimum flow.

c$.)$ Using the data in table $4.$ Determine the storage required to meet Konza City demand of $0\mathrm{.}25$ m$3/$s for the period from August $1994$ through January $1997$
