Abstract

Planning of water structures such as dams, irrigation canals, and other water structures require a description of a hydraulic flow phenomenon that these buildings. Each flow conditions before, moderate, and after passing through each building has its characteristics or tendencies. This study aims to analyze ignition characteristics by narrowing (sudden narrowing, transition, and Radius). Measurement of flow velocity is measured using a current meter and float tool (pimping ball) to obtain data: water level, flow velocity, observation review points before and after the channel narrowing. Understanding the flow characteristics of a narrowed channel is used to consider canals’ technical design, especially irrigation channels. The analysis shows that the flow of water through the narrowing experience changes in specific energy. The maximum specific energy loss occurs in a sudden constriction type. The predicted results correlate fairly with the experimental data from this and other studies.
