Group E
HW HWout =2.24m
HW100 : HWin = 2.7m > HWout =2.59m

alexyap @ 5:03 pm

group B answer

using box culvert
B=4.4m x D=1.5m

for Q 50yr HW= 2.54m
for Q 100yr HW= 2.97m

suhayati Abd Rahman @ 5:04 pm

Group E (revised)
HW HWout =2.24m
HW100 : HWin = 2.7m > HWout =2.59m

Group E
Inlet control
HW HWout2.24m
Q100 : HWin=2.7m > HWout 2.59m

Group E (revised answer as posted by suhayati)

HW HWout = 2.24m
HW100 : HWin = 2.70m > HWout = 2.59m
Therefore INLET control

Group D

Proposed box culvert 4.0m (B) x 2.0m (D)

For Q50 = 22.00m3/s ; HWi =2.6m > HWo = 1.88m (Inlet Control)
For Q50 = 25.40m3/s ; HWi =2.8m > HWo = 2.16m (Inlet Control)

HW (provided) = 2.8m < HW (required) = 3m

A.H.H.TIONG @ 5:23 pm

Group E (revised)

Hw Hwout = 2.24m
Hw100: Hwin = 2.70m > Hwout = 2.59m

Both is inlet control.

aniza @ 5:43 pm

Group E ( lastest attempt to comment)

For HW HWout=2.24m
For Q100, HWin=2.70m > HWout=2.59m
INLET controls

aniza @ 5:58 pm

Group E (try again)

For HW HWout 2.24m
For Q100, HWin 2.70m > HWout 2.59m
Both flows, INLET controls

khusairy @ 6:00 pm

group A

using twin box culvert size
B=2.1m D=1.8m Inlet Control
for Q50 HWin =2.43m > HWout=2.26m
for Q100 HWin =2.79m > HWout=2.56m

Group E(from GHD office)
Control HW < 3m
Proposed Box Culvert: 4.5m x1.5m
For Q50: HW inlet=2.37m,outlet=2.24m
For Q100: HW inlet=2.7m , outlet=2.59m
Therefore INLET CONTROL
