Assume location is SUNY Poly, Oneida County, NY$.$

Determine the Time of concentration using TR$-55$ Worksheet $3$ for the following drainage areas:

$1.$ Hydraulic path as described below:

Sheet $($overland$)$ flow: average grass, $100\text{'}$ long, $3\mathrm{.}5\%$ average slope

Shallow concentrated flow: $200\text{'}$ long, $3\mathrm{.}5\%$ average slope

Triangular Swale: $500\text{'}$ long, $2\mathrm{.}0\%$ average slopes $(8\text{'}$ wide, $1\text{'}$ deep midway, n$=\mathrm{.}025)$

$2-$Figure $10-22$ Drainage Basin $($sheet$,$ shallow concentrated and channel flow$).$ Assume channel is trapezoidal w$/4\text{'}$ flat bottom and $3($H$)$:$1($V$)$ side slopes.merial,
