Abstract

Accurate water measurement is one of the key factors for reduction of agricultural water consumption, distribution integrity and delivery management in irrigation networks. In recent years, there has been a significant advance in flow measurement devices, but the usage of these devices is limited due to the high cost, special maintenance conditions and the need for skill expertise. Water structure used in this study is a new form of flow measurement flume that installed along the channel and has cylindrical and conical shape walls. The crest matches the channel's floor thus in this measuring structure, the control section happens only by transversal constriction. The new flumes are simple in shape and easily applicable in irrigation networks and they have not sedimentation problem. The amount of energy loss and consequently the upstream backwater in this structure is low. This structure controls the flow by creating critical flow in constriction section and will be able to measure flow discharge. In this study, the flow characteristics through the cylindrical and conical flumes have been studied theoretically and experimentally, and several equations have been developed for flow discharge estimation in rectangular open channels.
