Análisis comparativo de tres métodos para la medición de caudales en canales abiertos

Abstract

For the execution of works and hydraulic structures such as water treatment plants, hydroelectric plants or sanitation works and sewerage networks is essential aqueduct and know the current flow or to be treated. Notwithstanding the determination of flow by conventional methods (specifically the pinwheel) it is sometimes difficult due to own stream conditions and the presence of rocks in the bed or large amounts of solids or materials of considerable size that jam the propeller equipment.

So this research raises the alternative of using other methods of flow capacity, in addition to gauging with pinwheel, also it plans to conduct gaugings tracer (NaCl or salt) and the flow capacity with floats (ping pong balls floating table).

Once gauging methods were determined to employ two monitoring points were selected: one located on the river career fucha with seventh and one in the river archbishop seventh race. For the first flow records were obtained with the methodology of pinwheel consistently similar to historical records flow; data pertaining to the District Department of Environment of Bogota. For the second site gauging, that is the river archbishop with seventh race, the same pattern was also given; flows near the historical flow records.
