PHYSICAL PROPERTIES

Elevation difference between the highest level of the intake and the lake surface is $1,32m.$ Rectangular channel base width

is measured to be $9,45m.$ I'he part between A and B is Earth, straight, and uniform with clean, recently completed surface

with a longitudinal slope of $S_{ob},$ where the section after B $($which is closer to the town$)$ is composed of Earth, straight,

and uniform with gravel, uniform section, clean surface with a longitudinal slope of $S_{az}.$

$S01=0,0176$ and $S02=0,0021$ and $y3=0,9m,$; $($ie$.$ for $n_f$ and $n_2$ use an acceptable tigures explaining the reason

and using references where appropriate.

Design:

a$.$ Be aware that the sketch above may not indicate the correct configuration of slopes! So find out the correct slope types,

check your slope condition $($steep or mild slope$)$ and proceed for calculations accordingly,

b$.$ Find out the discharge for the open channel,

c$.$ Find out the critical depth $y_o,$

d$.$ Find out normal depths of $y_1$ and $y_2,$

e$.$ If hydraulic jump exists, give the location of the jump $($on steep slope channel or on mild slope channel$),$ total length

and, depths before and after the hydraulic jump.

f$.$ If hydraulic jump is not expected, find out total length of the gradually varied flow curve using appropriate intervals and

calculate flow depths for each interval using Direct Step Method.

g$.$ Imagine $y_3$ depth is required further down the $S_{02}.$ Set your water depth and design your channel accordingly $($i$.$e$.$ by

changing the channel width or changing the bottom elevation$).$
