Flow Measurements in Open Channels Using Integrating-Floats

The flow measurements have increased importance in the last decades due to shortage of water resources resulting from climate changes that request high control available needed for different uses. classical technique open channel measurement by integrating-float method was measuring locations when there were no modern devices reasons, such as cost devices. So, use techniques taken place solve problem. present study examines integrating float and defines parameters affecting acceleration floating spheres flowing analyzed using experimental measurements. investigated theoretically, well many tests a fixed floor laboratory flume conducted. Different sizes solid plastic with weights used floats measure velocities then discharge computation. results indicate is feasible accurate low velocity channels. It desirable small specific gravity closer unity get more results. measured estimated discharges compared obtained some other common techniques. Good agreement between techniques, an error less than 2.5%.
