you use a tape measure two people stand on each side one has the tape measure and throws it holding the end onto the other side someone must go in and find the middle then add it by itself then that's how wide it is
There are a few ways of doing it.
Manually, you could just use the 'dip-stick' method of dropping in a straight object, lifting it back out and then measuring the wet part of the stick.
If you wanted an electronic measurement, there are a couple of methods. The easiest is probably a hydrostatic sensor.
A hydrostatic level sensor sits on the river-bed and transmits the amount of water that is directly overhead. You would want to drop the sensor into the deepest part of the river if you were looking for the maximum depth.
You check the scale on the map say 1cm=2metres then measure in centimeters the distance and convert it into metres. Basically you need to read the scale of the map and convert the units of measure :-)
Now days its done by satellite imaging, but still not 100%.
You stick a tape measure to the bottom of the river and measure how deep it is
A ruler to plot the base line at a convienent scale. Also a protractor will be useful. It depends on it's properties.

A quality parameter is a measuring device used to measure rivers, lakes, and ground water. This device can measure the way these bodies of water change.
The basic metric unit for length is the metre. Rivers would be measure in kilometres (1,000s of metres)
One reason is so boats and cargo ships can know if they will be able to pass through the river.
Rivers have been used as a source of water, for obtaining food, for transport, as a defensive measure, as a source of hydropower to drive machinery, etc.
During the expedition, they had to use math to measure the heights of mountains, the width and depth of rivers, also various astronomical observations, they had to measure longitude and latitude almost constantly, figure out temperature, etc. :)
Rivers rhymes with livers.
there are 105 rivers in the world and those are the major rivers
yes doc rivers is austin rivers father.
rivers in India(:
There are over 400 rivers in Wisconsin.
no rivers are not
