Measuring Stream Discharge Using Float Method Pdf Stream A floating body (block of wood or bottle partially filled with water) is used to measure the velocity of flow of water. the velocity is multiply by area of the channel to determine discharge and the brief procedure for discharge measurement is given below. This study explores the comparative accuracy of float based and current meter methods for measuring velocity and discharge in controlled water flow experiments. Float method – this method measures surface velocity. mean velocity is obtained using a correction factor. the basic idea is to measure the time that it takes the object to float a specified distance downstream. Briefly put, this method involves measuring the surface velocity of the water with a floating object, and then multiplying this velocity by the width and average depth of the channel. below is a form you can use to perform the calculations automatically, and below that are step by step instructions.

We demonstrate how to measure velocity with both the float method and with a velocity current meter and top setting wading rod. finally, we review the usgs measurement guidelines and explore the sources of error associated with this approach. To make observations in flowing water with the help of suspension equipment, the measuring equipment must be placed at the point of measurement in such a way that it does not cause appreciable disturbances, irrespective of the depth of water and velocity of flow. Learn water discharge measurement: volumetric, velocity area (float, current meter, adcp), & weirs. choose the right method for accuracy. Learn how to measure the velocity, discharge and cross sectional area of small streams. you will compare two methods of measuring discharge (q = av): current meter and float method.
