I'm trying to find out too :P But iv'e found this link :)

With wetted perimeter you simple use a measure tape and starting from one bank you run the tape along the sides and base of the channel including any bumps/holes you come across.
What else can I help you with?
Why is it important to measure perimeter and area?
It is important to measure area and perimeter or perimeter and area same thing any ways it's important because if you don't you will never find your answer
What word with a Greek root means a measure of distance around a specific area?
The word "perimeter" is from the Greek words peri(around) and métron (measure).
Is acetate absorbent?
Cellulose acetate is easily wetted.
Which unit of measurement would you use to measure the perimeter of a room?
Perimeter is a length or a distance, just like depth, height, and circumference are. Any unit of length can be used to describe a perimeter. Some good ones are ... - nanometer - inch - kilometer - parsec - furlong - yard - league - mile - light-year.
What unit would you use to measure a river?
The width of a river will generally be measured in feet or meters, depending on if you use Imperial or Metric.
How does bed load influence the wetted perimeter of a river?
The greater the wetted perimeter, the more friction the water encounters with the bed and sides. This reduces the speed of the river.
Why does the rivers wetted perimeter increase as we travele downstream?
Because the Width and Depth both increase downstream. This means the wetted perimeter will also increase.
Why is the more wetted perimeter in lower course?
In the lower course of a river, the channel is typically wider and deeper due to erosion and sediment transport, resulting in a greater wetted perimeter. This increased wetted perimeter allows for more water contact with the riverbed and banks, influencing flow dynamics and habitat availability. Additionally, the flow is often slower in the lower course, which can lead to a more pronounced interaction between the water and the surrounding environment.
If a deep river is faster why doesnt the larger wetted perimeter increase friction and slow down the speed of the river?
The speed of a river is affected by the amount of friction slowing down the water and the grade or fall of the river. The amount of friction is determined by how rough the bed or wetted perimeter is, and how big the perimeter is. A wide shallow river or a very deep and narrow river with the same volume and grade will be in contact with similar areas of river bed, causing the same amount of friction. But a river with a semi circular shape in cross section and the same volume and grade will have less contact area with the river bed and will therefore have less friction and be faster. The steeper the grade of the river, the faster it will flow.
What is hydraulic mean radius?
Hydraulic Mean Radius = Cross sectional area of conduit divided by the inside (wetted) perimeter.
Does wetted perimeter decrease downstream?
No, it increases as there is more water in the channel.
What is hydraulic means?
Hydraulic Mean Radius = Cross sectional area of conduit divided by the inside (wetted) perimeter.
What is used to measure a perimeter?
to measure the perimeter we need a figure with boundaries and all the sides with dimensions
What are perimeter?
in math terms, the perimeter is the measure around the shape.
Is perimeter calculated in square feet?
Perimeter is in feet and not in square feet
Can a perimeter have 11 units?
The measure of a perimeter can be any positive number.
