Comparison between the float method and the Discharge application, Mascota irrigation channel case

Abstract

     The present work makes a comparison between the Discharge application and the float method to identify which is more feasible in measuring the flow of the irrigation canal in the municipality of Mascota Jalisco. As a first point, the geolocation of the three sites to be measured on the canal was carried out using discharge, where the measurements of both methodologies were carried out. The measurements made with the discharge application were made by processing images taken from the camera of a mobile device, where the mandatory conditions taken into account for the calculation are: channel profile, width, depth and roughness; obtaining a quick measurement of the speed, flow rate and flow level; These results are stored in the cloud of the web application. In the case of the implementation of the float method, the geolocation of the three points to be measured carried out with discharge was used, identifying at each site the points A and B 10 meters away using a tape measure; to determine the depth of both points, a graduated rod was used, once having these data, the flow velocity measurement was carried out by throwing a Styrofoam ball from point A to point B using a stopwatch, making three repetitions of measurement in each site obtain the standard measurement; the aforementioned method is totally manual, it is not possible to use it if there is turbulence in the channel.
