Some useful information is provided as follows.

$H=E{L}_{h0}-E{L}_0-h_o$

$H=H_e+H_f+H_0$

$H_e$ : Entrances loss

$H_o$ : Exit loss

$H_f$ : Friction loss

$E{L}_0$ : Elevation at the outlet of the culvert

$E{L}_i$ : Elevation at the inlet of the culvert

$E{L}_{h0}$ : Outlet control head water elevation

Where, $h_o=$max$[TW,\frac{D+y_c}{2}]$

$E{L}_0=E{L}_i-S_{o}L$

L: Length of the culvert

$S_0$ : slope of the culvert.

FIGURE:

The following is a similar problem to your lab problems that I solved in class. However, I have changed the flow and entrance type $($see on the bold$).$ Please analyze the following culvert.

Analyze a $5ft**5ft,$ square$-$edged entrance reinforced concrete box culvert for a roadway crossing to pass a $50-$year discharge of $200cfs$ with the following site conditions

Shoulder elevation $=113\mathrm{.}5ft$

Streambed elevation at culvert face $=100ft$

Natural stream slope $=2\%$

Tailwater depth $=4ft$

Approx. Culvert length $=250ft$

Max. Upstream water surface elevation $=110ft$

Analyze the above culvert for a $45-$degree wing wall flares$-$offset entrance and $Q=300$ cfs$.$ Assume all other information are same as given in problem $1.$

Analyze the culvert problem $1$ for a size of $5ft$ by $4ft$ square$-$edged entrance. Consider all other information are same including Q$.$
