“…The highest average control volume per control location over all identification strategies is achieved for Geel, the largest of the investigated catchments featuring several long collectors with considerable storage potential. This is in line with literature stating that larger catchments show higher potential for the successful application of RTC [16,17]. Figure 4 visualizes the results of the sensitivity analysis for the relative effect of the variation of parameters shown in Table 3 (RTC scenarios) and Table 4 (uncontrolled scenarios) on total CSO volume and total flood volume.…”

“…Rather unexpectedly, the smallest catchment with the lowest PASST score still shows a noteworthy reduction in excess of 20%. This discrepancy between the results of the implemented RTC strategies and the PASST screening suggests that, while screening methods such as [16,17] can give a good indication whether or not the implementation of RTC can lead to performance improvements, an exact ranking based on these methods should be avoided.…”

While real-time control (RTC) is considered an established means of performance improvement for existing urban drainage networks, practical applications are frequently only documented for large case studies, and many operators are still reluctant to adopt RTC into their own systems. The purpose of the presented study is to highlight the potential of RTC also for smaller networks by the example of five representative catchments in Flanders, Belgium, and to demonstrate a novel methodology for the automated design of control strategies. This method analyses a given sewer network for the identification of suitable existing and new control locations. The gathered information is used in a second step for the design of control algorithms according to generic control concepts documented in the literature, such as e.g., “Equal Filling Degree”. The resulting RTC strategy uses sensible default parameters, and can form a starting point for further refinement through optimization or manual tuning. With a modelled total combined sewer overflow volume reduction of 20% to 50%, the created strategies showed generally good performance for the tested catchments. The method proved to be applicable for all tested networks. Its use for the real-life implementation of RTC is currently under way for 10 other Flemish cases.

“…Various real-time control (RTC) techniques of hydraulic facilities have been classified as independent NSMs, NSMs combined with SMs (combined measures), and NSMs combined with the same type of NSMs (integrated NSMs). Most RTC techniques in urban areas are independent NSMs for urban drainage facilities [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Several studies such as combined measures have been introduced to increase the efficiency of urban drainage systems (UDSs) [1,17].…”

The frequency of inundation in urban watersheds has increased, and structural measures have been conducted to prevent flood damage. The current non-structural measures for complementing structural measures are mostly independent non-structural measures. Unlike the current non-structural measures, the new operating technique based on flood forecasting is a real-time mixed measure, which means the combination of different non-structural measures. Artificial rainfall events based on the Huff distribution were used to generate preliminary and dangerous thresholds of flood forecasting. The new operation for centralized and decentralized reservoirs was conducted by two thresholds. The new operation showed good performance in terms of flooding and resilience based on historical rainfall events in 2010 and 2011. The flooding volume in the new operation decreased from 6617 to 3368 m 3 compared to the current operation in 2010, and the flooding volume in 2011 decreased from 664 to 490 m 3 . In the 2010 event, the results of resilience were 0.831835 and 0.866566 in current and new operations, respectively. The result of resilience increased from 0.988823 to 0.993029 in the 2011 event. This suggestion can be applied to operating facilities in urban drainage systems and might provide a standard for the design process of urban drainage facilities.
