  • Efficient investigation on fully developed flow in a mildly curved 180° open-channel

    Turbulent flow in meandering open channels is one of the most complicated and unpredictable turbulent flows as the interaction of various forces, such as pressure gradient, centrifugal force, and wall shear stresses severely affect the flow pattern. In order to improve significance in engineering application, understanding the overall flow characteristic is the focus. This paper presents the ...

  • Measuring Wastewater Below Ground

    Measuring wastewater is one of the most difficult water management tasks that exists. While some wastewater flows are easy to access, others are very hard to measure because they are in open channel conditions and are below grade. If you need to measure below ground wastewater flow, there are a few factors that you need to consider to help you choose the right tool for the job. With a ...

  • Flood modeling and mitigation measures in an urban environment – a Case Study, Victoria, Australia - Case Study

    Introduction: Flooding on urban basins is intensifying due to rapid urbanization. Flooding primarily occurs because of drainage congestion of inland flow and/or over bank flow of rivers during severe rainfall events. Rapid urbanization is causing a major change in rainfall-runoff phenomenon and the drainage system as well. The overland flow pattern is becoming complex due to huge structural ...
