“…It has suitable numerical solutions for the flow characteristics of physical problems such as steady and unsteady flow, laminar flow, and turbulence and achieves the best in terms of calculation speed, stability, and accuracy, so as to reveal its comprehensive performance. Daal-Rombouts et al combined lab experiments and field measurements to demonstrate that the complex hydraulic behavior, including a flow regime change, can be precisely simulated [15]. A similar conclusion is obtained by Dufresne et al [10], who employed particle image velocimetry and acoustic Doppler velocimetry to measure the flow field, and compared to the simulated results.…”

The confluence overflow facility with transverse weir is adopted in China to reduce the occurrence of overflow. Under normal conditions, most of the facilities do not overflow. The study on the hydraulic structure without overflow is helpful to improve the pollutant interception efficiency. In addition, the weir height equation for different intercepting pipe diameters was required. Full scale experiments and simulation studies were carried out, and the reliability of the simulation results was verified by experiments. The simulation describes the hydraulic structure and shows that the backflow area appears on the side of the chamber away from the interceptor and at the inlet of the pipe. The results show that when the ratio of weir height to pipe diameter is less than 1.2, the closure pipe is non pressure closure, when the ratio is from 1.2 to 1.75, it becomes half pressure, and when the ratio is greater than 1.75, it is converted to pressure. The increased rate of intercepting flow with the rise of weir height would change under the effect of different flow characteristics. Based on the experimental data distribution and the hydraulic characteristic, the weir height equation was deduced for the pipe diameter of 0.4 m. Other pipe diameter simulations showed that this equation was also applicable.

“…The high temporal and spatial variability of pollution flow would require RTC to distinguish between highly polluted and less polluted flows. Pilot studies show promising results using conductivity and turbidity sensors as real-time surrogates for pollution potential . Such information coupled with RTC, in the near future, would allow stormwater discharge to be managed on the basis of the impact potential on the receiving water body. MPC is an advanced RTC technique, in which the optimization is based not only on the knowledge of the current state of the system but also on its forecast state.…”

The promise of collecting and utilizing large amounts of data has never been greater in the history of urban water management (UWM). This paper reviews several data-driven approaches which play a key role in bringing forward a sea change. It critically investigates whether data-driven UWM offers a promising foundation for addressing current challenges and supporting fundamental changes in UWM. We discuss the examples of better rain-data management, urban pluvial flood-risk management and forecasting, drinking water and sewer network operation and management, integrated design and management, increasing water productivity, wastewater-based epidemiology and on-site water and wastewater treatment. The accumulated evidence from literature points toward a future UWM that offers significant potential benefits thanks to increased collection and utilization of data. The findings show that data-driven UWM allows us to develop and apply novel methods, to optimize the efficiency of the current network-based approach, and to extend functionality of today's systems. However, generic challenges related to data-driven approaches (e.g., data processing, data availability, data quality, data costs) and the specific challenges of data-driven UWM need to be addressed, namely data access and ownership, current engineering practices and the difficulty of assessing the cost benefits of data-driven UWM.
