Using the Connecticut watershed example discussed in HW$1,$ we have the following data:

a$.$ For the Connecticut watershed estimate the mean annual regional PET using

equation $2$B$4\mathrm{.}2$

b$.$ Then determine a best$-$fit value of the average storage parameter $w$ in the

Budyko equation $[$equation $2\mathrm{.}12]$ by programming the equation in Excel or R$,$

adjusting the value $w$ until the calculated value of $RO$ most closely

approximates the value for your watershed.

c$.$ Estimate the elasticity of runoff to precipitation via equation $2$B$4\mathrm{.}1.$ In addition

to giving the numeric value, write a few sentences that explain in layman's

terms what this means.

d$.$ Estimate the relative change in runoff due to a temperature increase of $1C$ via

equation $2$B$4\mathrm{.}7.$
