How to Calculate Weight of a Rock Hunker
Having established the width of the river, the next job is to find it's depth at regular intervals across it's width. The number of readings taken will depend upon the width of the river and the amount of detail you require. For most rivers intervals of 50cm are a good compromise between excessive work and Ö... River cross profiles show you a cross-section of a riverís channel and valley at certain points in the riverís course. The cross profile of a river changes as it moves from the upper to lower course as a result of changes in the riverís energy and the processes that the river carries out.

I've developed a formula for the average width of a polygon and put it into a Python/ArcPy function. My formula is derived from (but substantially extends) the most straightforward notion of average width that I've seen discussed elsewhere; that is, the diameter of a circle having the same area as your polygon.... How how many measurements you chose to take will depend on the variability of the channel depth and the width of the river channel. Divide width measurement by 10. e.g. `"Width" = 1.20m` so `"width"/10 = 0.12m or 12cm` Use this interval to measure at 9 equally spaced points across the channel. With a metre rule measure from the water surface to the river bed. To ensure accuracy, turn the metre
18/05/2014†∑ In this video I demonstrate how to measure the cross section of a stream using some measuring tape and a metre ruler. Filmed in New Zealand. Check out Ö how to turn bullet points into a paragraph 18/06/2007†∑ The discharge of a river can be estimated by taking the area of a cross-section of the river and multiplying it by the river's average velocity.
How do you calculate river discharge? Yahoo Answers
Average depth. Depth of the deep end @ 8'. Depth of the shallow end 3'. Add the two together and divide by 2 = average. Ken Depth of the deep end @ 8'. Depth of the shallow end 3'. how to use ugg leather care kit We can work out the dimensions of the middle section because we know the path around the edge is 2m wide. The width of the whole shape is 16m the width of the path across the whole shape is 4m (2m on the left of the shape and 2m on the right). 16m - 4m = 12m

How To Work Out The Width Of A River
Size, shape, orientation and slope of the block of land. Got a particular house style or design in mind? Itís not normally a problem on bigger plots, but in suburban and urban areas, the width and depth of the plot will determine what sort of house you can build.
- 5/03/2008†∑ Best Answer: You have to know two things: The area of the flow and the speed of the flow. To get the area you have to measure the depth and width of the river at a particular cross-section perpendicular to the flow direction.
- The river-bottom tracking capability of the ADCP acoustic beams or a Global Positioning System (GPS) is used to track the progress of the ADCP across the channel and provide channel-width measurements. Using the depth and width measurements for calculating the area and the velocity measurements, the discharge is computed by the ADCP using discharge = area ? velocity, similar to the
- If the width of the river is X meters wide, then how much time does it take the boat to travel shore to shore? What distance downstream does the boat reach the opposite shore? The first of these three questions was answered above; the resultant velocity of the boat can be determined using the Pythagorean theorem (magnitude) and a trigonometric function (direction).
- To work out the size and width you will require, please follow these steps: Measure the length of your foot by standing on a flat surface with your full weight on your foot, then measure the distance from the back of your heel to the tip of your longest toe.
